【正文】 earch that the soil pollutes the evaluation in the soil bring of risk valuation USE PA drew up in 1989 a kind of according to a little bit particular of, made use of mathematics model fixed amount to turn the calculating risk evaluation method, this method related to the revelation, a quantity reflection of the pollutant and farm crop to reflect to relate to all quantity of etc. to turn to evaluate by carry on the Ⅲ 39。.The evaluation method of the ANZECC adoption is similar to USEPA, the biggest dissimilarity lie in, it think because lack valid, the data of science, the fixed amount turn of carry on what the risk evaluation is to can39。t carry out, only ability according to uninfluenced reflection level of the inquisition level and the protection ecosystems of the environment and health, draw up the risk of a half fixed amount evaluation Theelen think if exceeded to the mankind and the risk of the ecosystem system to define in advance biggest to is tolerant of the risk degree, the soil pollution of the so particular location is to can39。t accept of, or say that is insecure old . the Ronald makes use of the pollution of the in proper order ratings method evaluation heavy metals to soil old, B. the Antonio studied the polluting evaluation degree ∞ J of the soil recent years, the USEPA starts adopt to receive especially card Luo the method( the monte carlo) carries on the polluting risk evaluation of the soil heavy metals, is in some revelation evaluations particularly, pass to imitate the condition that a series choose random but evaluate each risk parameter, receive especially card Luo the analysis can produce a latent risk all the rate estimate, this evaluation method pares the traditional evaluation method to even have the advantage. our country soil heavy metalses pollute the research dynamic state of evaluation longFor long time, because of lacking the enough understanding to the bane that soil pollute, result in our country soil the pollution aggravates increasingly, in recent years soil safety and the healthy problem of the farm crops that aim at the soil heavy metals pollution and bring from here, the local scholar carried on a great deal of thorough research, putting forward a series of soil heavy metals pollution evaluation of related standard, means and method.Some scholars of our country return to contact the soil background together critical content of soil evaluation and analysises that carries on the soil pollution for the standard, the critical value of soil also calls it as the environment quantity basis, it mainly carries on the establishment through the geochemistry method and the ecosystem environment effect critical content of the soil pollutant is apply in the soil heavy metals extensively in the polluting ratings evaluation, the such as the leaf namely with the background of the soil be worth and critical value for basic parameter, convert the migratory regulation in the farmland soil according to the pollutant and to the farm crop, the healthy risk that etc. may result in of of person is divided into the soil environment quantity 5 Class, carry on the evaluation to the environment quantity of the farmland soil.The our country promulgate the People39。s Republic of China soil environment quantity standard in 1995( GBl5618?1995), That standard is divided into the soil environment quantity according to the soil applied function and the protection targets 3, carried on the demarcation of the xrated standard at the same promulgation implement of this standard provided the new basis for the ratings that the our country soil pollute and some scholar namely took the soil environment quantity standard as the standard to open the exhibition research work of the homologous soil pollution ratings evaluation, such as WU2 ZHI4 FENG according to the national soil environment quantity standard of second class standard to Guangzhou long the seedling soil environment quality carried on most analysis, get homologous evaluation have in addition with sweep the soil to check against some content as evaluation in the district standard, but because of everyplace the area soil in the chemical element content difference very big, use this kind of method be the evaluation result of, can reflect the district only opposite in sweep the basic condition of the area, evaluate the result and did not be able to pare sex, so work physically medium application less.The our country soil heavy metals pollution evaluation method of in the selection, adopt the singleitem pollution index number and prehensive pollution index numbers generally two kinds of to evaluate the soil of pollution condition. in acquiring the foundations of the singleitem pollution index number, often in prehensive pollution index number of the pollution index number type calculation soil of Luo of plum, it can with outstanding the functions that pollute the heavier pollutant, thus acquire total environment quantity condition in addition to the pollution index number method, in recent years, the domestic research concerning the soil heavy metals pollution evaluation method increases gradually, main beneficial with 71 value ratings method Ⅲs that the grade point means to pollute the degree 1, because the r value ratings method evaluation the soil quantity is too rough, can evaluate an at all point pollution Class only, can39。t pursue a row misty mathematics theories and gray system theories for someone immediately after in produced misty mathematics prehensive evaluation method Ⅲ o and gray to gather a method mo from here in the soil heavy metals pollution evaluation, lead this 2 kinds of methods carries on the improvement, into the total inclined rate gray gathers a method and breadth area grays to gather a method etc., in addition, our country the in mon use evaluation method still has the basis analysis method, the diagram theory to gather a method, the contamination rate metho
