防治土壤污染 守護(hù)沃土良田

文/吳平

“日月麗乎天，百谷草木麗乎土”，土壤承載著人類與萬物的生存繁衍。然而長(zhǎng)期以來，經(jīng)濟(jì)社會(huì)快速發(fā)展，土壤污染卻一直困擾我國(guó)。土壤本身的特性決定了其污染易、修復(fù)難，投入大、見效慢?？梢灶A(yù)見，土壤污染防控必然是我國(guó)政府向污染“宣戰(zhàn)”的重要一役，既是持久戰(zhàn)又是攻堅(jiān)戰(zhàn)。

As the old saying goes that “the sun and the moon run in the sky and the plants grow in the soil”,it shows that soil carries the survival and reproduction of human beings and all things on earth.However,for a long time,with the rapid development of economy and society,the country is still haunted by soil pollution.Characteristics of the soil itself determine it easy to cause pollution and difficult to restore,which costs large input but is slow to take effect.It is foreseeable that the prevention and control of soil pollution will inevitably become an important campaign of the Chinese government to “declare war” against pollution.It will not only be a protracted war but also a tough fight.

對(duì)于嚴(yán)重污染的土壤修復(fù)進(jìn)度緩慢

The process is slow to restore the heavily polluted soil

我國(guó)土壤環(huán)境狀況總體不容樂觀，耕地和工礦用地污染較為嚴(yán)重，污染物以重金屬等無機(jī)物為主。根據(jù)《全國(guó)土壤污染狀況調(diào)查公報(bào)》，從總體格局上看，全國(guó)土壤總超標(biāo)率達(dá)16.1%；從污染物構(gòu)成看，鎘、鎳、砷分別以7.0%、4.8%、2.7%的點(diǎn)位超標(biāo)率成為最主要的污染物，滴滴涕、多環(huán)芳烴等污染物點(diǎn)位超標(biāo)率也相對(duì)較高。隨著資源能源消耗和人為活動(dòng)強(qiáng)度的持續(xù)增加，土壤環(huán)境保護(hù)面臨的壓力持續(xù)增加。

China’s soil environmental conditions in general are not optimistic,arable land and industrial and mining land are heavily polluted and the pollutants are mainly the heavy metals and other inorganic substances.According to theBulletin on National Soil Pollution Survey,it can be seen from the overall pattern that the total over-standard rate of soil in the country reached up to 16.1%.From the composition of pollutants,cadmium,nickel and arsenic became the major pollutants with the respective point over-standard rate of 7.0%,4.8% and 2.7%.In addition,the point over-standard rate of DDT,PAH and other pollutants were also relatively high.With the resources and energy consumption and the intensity of human activities continue to increase,soil environmental protection also faces the increasing pressure.

在土壤環(huán)境狀況不容樂觀的條件下，修復(fù)工作任重道遠(yuǎn)。當(dāng)前，土壤修復(fù)已得到各級(jí)政府的重視，在國(guó)務(wù)院頒布“土十條”的基礎(chǔ)上，福建、安徽等20個(gè)省區(qū)市已公布地方版“土十條”，在分解細(xì)化國(guó)家標(biāo)準(zhǔn)之外，突出地方土壤環(huán)境特色：如黑龍江、吉林將黑土地列為治理重點(diǎn)之一。然而，當(dāng)前我國(guó)土壤修復(fù)能力仍然受到技術(shù)和資金的制約。技術(shù)方面，與大氣污染和水污染治理不同，土壤修復(fù)耗時(shí)長(zhǎng)、耗力大，處理過程更復(fù)雜，此外，土壤類型多樣，受體（生物、水體、空氣、人體等）類型眾多，導(dǎo)致土壤修復(fù)技術(shù)也比較復(fù)雜。目前，我國(guó)不少土壤修復(fù)技術(shù)仍停留在實(shí)驗(yàn)室水平，尚沒有形成行之有效的技術(shù)體系，關(guān)鍵設(shè)備仍須進(jìn)口。資金方面，當(dāng)前土壤修復(fù)資金主要依賴政府部門和土地開發(fā)商，而排污企業(yè)等造成土壤污染的主體由于產(chǎn)權(quán)不明、規(guī)模有限等原因難以提供足夠的資金，“誰污染，誰治理”的原則并未得到有效遵從，致使我國(guó)土壤修復(fù)能力難以快速提高，增量污染問題依然嚴(yán)峻，“毒地”現(xiàn)象屢見不鮮。

Under the circumstance that the soil environment conditions are not optimistic,there is a long way to go for soil restoration.At present,soil restoration has received attention from the governments at all levels.Based on the10-Chapter Soil Pollution Action Planissued by the State Council,the local10-Chapter Soil Pollution Action Planhas been published in 20 provinces,autonomous regions and municipalities such as Fujian,Anhui and so on,which highlighted the local characteristics of the soil environment in addition to decomposition and refining of the national standard.For example,Heilongjiang and Jilin list the black soil as one of the governance emphases.However,the current soil restoration capacity in China is still subject to technical and financial constraints.When it comes to technology,unlike governance of air pollution and water pol-lution,soil restoration is time-consuming and labor-intensive,and the process is more complicated.Plus the diverse soil types and numerous receptor (organism,water,air,human body,etc.) types,so the soil restoration technology is also complex.At present,many soil restoration technologies in China are still at the laboratory level and there is no effective technical system at present,as a result of which the key equipment still need to rely on imports.With regard to funds,the current soil restoration funds rely on government departments and land developers,but it is difficult for polluting enterprises and other subjects causing soil pollution to provide sufficient funds due to unclear property rights,limited scale and other reasons,and the principle of “whoever causes pollution is responsible for its treatment” is implemented with difficulty and is hard to be pushed forward,resulting in China’s soil restoration capacity is difficult to gain rapid increase,still grim incremental pollution and common phenomenon of “toxic soil”.

制度短板是重要的制約因素

System shortcomings restrict soil restoration

“看得見的污染，看不見的制度”。當(dāng)前土壤污染防治除技術(shù)性障礙之外，還存在一些制度空白，這些空白成為提升土壤污染防治工作的瓶頸。只有彌補(bǔ)制度缺失，才能為治理開門引路、保駕護(hù)航。

“Pollution is visible while system is invisible”.At present,there are some gaps in the system in addition to technical difficulties for prevention and control of soil pollution,resulting in the bottleneck for enhancing prevention and control of soil pollution.Therefore,only by making up for the lack of system can we lead the way and escort for governance.

一是污染底數(shù)不清，現(xiàn)有數(shù)據(jù)較為粗糙。土壤污染的“家底”是所有防治工作的前提和基礎(chǔ)。我國(guó)尚未建立起按照污染程度進(jìn)行分類的農(nóng)用地清單和污染地塊清單，監(jiān)管依據(jù)不足。盡管《全國(guó)土壤污染狀況調(diào)查公報(bào)》公布了一些土壤污染檢測(cè)數(shù)據(jù)，但是調(diào)查點(diǎn)位設(shè)置較為稀疏，數(shù)據(jù)難以準(zhǔn)確代表土壤污染的分布和狀況，部分地區(qū)甚至缺乏監(jiān)測(cè)點(diǎn)位和人員配置。因此，亟須以農(nóng)用地和重點(diǎn)行業(yè)的企業(yè)用地為重心開展土壤污染狀況的詳細(xì)測(cè)查。

Firstly,pollution is incomputable and the existing data is not accurate.To have a clear understanding of soil pollution is the prerequisite and basis for all prevention and control.Since China has not yet established the farmland list and polluted land list to be classified by degree of pollution,supervision basis is insufficient.Bulletin on National Soil Pollution Surveyreleased some test data of soil pollution,but the survey point is set to be more sparse,making the data difficult to accurately reflect the distribution and status of soil pollution,and even lack monitoring points and staffing in some areas.Therefore,we are in the urgent need to carry out a detailed survey on soil pollution with the focus on farmland and land for enterprises in major industries.

二是制度體系尚待完善，法治保障仍須加強(qiáng)。當(dāng)前，我國(guó)的土壤污染法律體系還未建立，相關(guān)規(guī)定分散于其他環(huán)境污染法律法規(guī)中，法律缺位致使法律責(zé)任、主體等方面的認(rèn)定存在難度，從而加大了有關(guān)土壤污染違法案件的處理難度；此外，目前我國(guó)較少采用經(jīng)濟(jì)手段，如引導(dǎo)市場(chǎng)行為的鼓勵(lì)政策。美國(guó)在土壤污染的管理方面，以《環(huán)境應(yīng)對(duì)、賠償和責(zé)任綜合法》為基礎(chǔ)建立了超級(jí)基金場(chǎng)地管理制度，包括責(zé)任追究、修復(fù)響應(yīng)和污染賠償，有力地震懾了污染行為人，反過來起到了污染防治的效果。由于監(jiān)管未實(shí)現(xiàn)完全的有法可依，加上各地土壤環(huán)境監(jiān)測(cè)、監(jiān)督執(zhí)法、風(fēng)險(xiǎn)預(yù)警體系建設(shè)嚴(yán)重滯后，難以對(duì)土壤環(huán)境實(shí)施有效監(jiān)控。

Secondly,the system has yet to be improved and the law guarantee needs to be strengthened.At present,China’s soil pollution legal system has not yet been established,and relevant provisions are scattered in other environmental pollution laws and regulations.Legal system can prevent soil pollution violations,however,the current lack of legal absence makes it difficult for identifying legal responsibilities and subjects and so on,exacerbating the difficulty of dealing with cases in relation to soil pollution violations.At the same time,the law can also provide for the means of pollution control,and now less economic means is adopted in China,such as incentives to guide the market behavior.In the aspect of management of soil pollution,the United States has established a superfund site management system based onEnvironmental Response,Compensation and Responsibility Law,which includes accountability,restoration response and pollution compensation,serving as a strong deterrent to the polluters,which also becomes effective in pollution prevention and control in turn.In addition,due to legal basis is not fully realized,plus the seriously lagging soil environment monitoring,supervision and law enforcement and construction of risk early warning system in various places,it is difficult to exercise effective monitoring of soil environment within the area under administration.

三是標(biāo)準(zhǔn)規(guī)范精細(xì)度低，技術(shù)體系亟待完善?，F(xiàn)行的土壤環(huán)境標(biāo)準(zhǔn)不健全，使得目前土壤環(huán)境污染評(píng)價(jià)與分區(qū)都缺乏適當(dāng)?shù)囊罁?jù)。目前執(zhí)行的《土壤環(huán)境質(zhì)量標(biāo)準(zhǔn)》（1995）粗略且針對(duì)性弱，雖然2014年環(huán)保部發(fā)布了建設(shè)用地土壤環(huán)境調(diào)查、監(jiān)測(cè)、評(píng)估、修復(fù)系列標(biāo)準(zhǔn)作為補(bǔ)充，但總體上看還存在諸多問題。一是土壤標(biāo)準(zhǔn)制定過于要求統(tǒng)一，并未充分考慮我國(guó)土壤類型復(fù)雜的現(xiàn)實(shí)情況，沒有因地制宜；二是污染物項(xiàng)目較少，尤其是有機(jī)污染物種類偏少；三是重金屬污染物指標(biāo)雖注重總量控制，但土壤污染主要是由有效態(tài)構(gòu)成，總量控制情況不能準(zhǔn)確地反映土壤受到的實(shí)際影響；四是現(xiàn)行標(biāo)準(zhǔn)的制定未充分考慮土壤對(duì)生物受體的毒性效應(yīng)。

Thirdly,the standard specification is not refined and the technical sys-tem needs to be improved.The existing soil environmental standard is not sound,making the current soil environmental pollution assessment and zoning lack appropriate basis.The existingSoil Environment Quality Standard(1995) is rough and less pertinent.Although the Ministry of Environmental Protection issued a series of standards for soil environment survey,monitoring,evaluation and restoration in construction land as a supplement,there are still many problems on the whole.First,too much emphasis is placed on establishment of soil standard and the reality of complex soil types in China is not fully taken into account,which fails to achieve adjusting measures to local conditions.Second,there are less pollutant projects,especially there are less types of organic pollutants.Third,heavy metal pollutant indicators focus on the total quantity control,but the soil pollution is mainly composed of the effective state,so the total quantity control cannot accurately reflect the actual impact of the soil.Fourth,establishment of the existing standard does not fully consider the toxic effect of soil on the biological receptors.

政策與市場(chǎng)雙重助力

Soil restoration requires the double assistance of policy and market

防治土壤污染，完善制度先行。首先，結(jié)合“土十條”，加快土壤污染防治立法。堅(jiān)持“保護(hù)優(yōu)先、預(yù)防為主、防治結(jié)合”的方針和“分類、分區(qū)、分目標(biāo)管理”的原則，建立符合中國(guó)國(guó)情的土壤污染防治體系。在防治體系中重點(diǎn)要設(shè)立公平合理的責(zé)任認(rèn)定原則，并根據(jù)不同的法律責(zé)任主體規(guī)定相應(yīng)的法律責(zé)任，誰污染，誰負(fù)責(zé)。其次，盡快修訂《土壤環(huán)境質(zhì)量標(biāo)準(zhǔn)》等相關(guān)標(biāo)準(zhǔn)。再次，創(chuàng)新監(jiān)管模式，提升監(jiān)管能力。

Firstly,system improvement shall go ahead for prevention and control of soil pollution.First of all,we must combine with the implementation of the10-Chapter Soil Pollution Action Planto speed up legislation for prevention and control of soil pollution.We shall adhere to the policy of“protection first,prevention orientation,prevention and treatment combination” and the principle of “classification,zoning,sub-target management” to establish the system for prevention and control of soil pollution that is in line with China’s national conditions.In the prevention and control system,we shall set up the principle of fair and reasonable responsibility,and stipulate the corresponding legal responsibility according to the different legal liability subjects,and practice the principle of “whoever causes the pollution shoulders the responsibility”.Second,we shall amendSoil Environment Quality Standardand other standards as soon as possible.Third,we shall bring new ideas to supervision mode to enhance supervision capacity.

制定市場(chǎng)規(guī)則，刺激修復(fù)活力。土壤修復(fù)要善于利用經(jīng)濟(jì)手段，重點(diǎn)在于制定市場(chǎng)規(guī)則、引導(dǎo)資源配置。在投融資、稅收、補(bǔ)貼等方面，扶持跨區(qū)域、區(qū)域內(nèi)環(huán)保設(shè)施統(tǒng)一規(guī)劃、統(tǒng)一建設(shè)、統(tǒng)一運(yùn)營(yíng)，實(shí)現(xiàn)環(huán)?；A(chǔ)設(shè)施一體化管理。通過政府和社會(huì)資本合作（PPP）模式，加大政府購(gòu)買服務(wù)力度，帶動(dòng)更多社會(huì)資本參與污染協(xié)同治理。發(fā)揮政策性和開發(fā)性金融機(jī)構(gòu)的引導(dǎo)作用，為跨區(qū)域、多介質(zhì)協(xié)同治理的重大污染防治項(xiàng)目提供支持。

Secondly,we shall make market rules to stimulate the restoration vitality.Soil restoration also requires good at utilizing of economic means,focusing on the development of market rules to guide allocation of resources.When it comes to investment and financing,taxation and subsidies,we shall support the unified planning,construction and operation for environmental protection facilities in the region and achieve integrated management of environmental protection infrastructure.We shall increase government’s procurement of services through the government and social capital cooperation (PPP) mode to mobilize more social capital to participate in synergistic governance of the pollution.In addition,we shall play the guiding role of policy and development financial institutions to provide support for major pollution prevention and control projects for cross-regional and multi-media co-governance.

呼喚可實(shí)踐、符合現(xiàn)狀需求的新技術(shù)。我國(guó)污染土壤修復(fù)技術(shù)的研發(fā)應(yīng)該為解決農(nóng)田、工業(yè)場(chǎng)地、礦區(qū)及周邊土壤污染以及生態(tài)敏感的濕地土壤污染等問題提供技術(shù)支持，這就要求研發(fā)出能應(yīng)用于不同土壤類型與條件、不同土地利用方式和不同污染類型與程度的土壤修復(fù)技術(shù)。

Thirdly,we shall call for the practical new technology that is in line with the current needs.China’s research and development of polluted soil restoration technology shall provide technical support for solving problems such as soil pollution in farmland,soil pollution in industrial sites,soil pollution in mining areas and surroundings and soil pollution in ecologically sensitive wetland,which requires research and development to apply to different soil types and conditions,different soil utilization modes and the soil restoration technology with different pollution types and degrees.
