江苏省溧水县土壤环境污染预警预测方法探讨

Discussions on prediction and precaution methods for soil environment pollution in Lishui County,Jiangsu Province

介绍了溧水县土壤环境质量的现状。溧水县主要有黄砂土、栗色土、岗黄土、黄岗土、马肝土、板浆白土、青泥条、青泥土等8种土壤类型。通过地球化学调查和对溧水县土壤的系统采样,获得了反映土壤质量的地球化学数据。通过对土壤中污染物富集历史的研究,揭示了土壤污染物的演化趋势。通过寻找零污染的历史时间结合现代土壤地球化学调查数据,建立了土壤重金属污染预警预测的数学模型。提出了影响土壤质量的关键因子和土壤污染的影响因素,得出了工业是影响土壤质量的主要因子,土壤污染在不断加速的结论。

The present soil environmental conditions in Lishui County are presented in the text. There are eight soil sorts in Lishui County. Through geochemical investigation and a systematic sampling of soils,the concerned geochemical data on the quality of soils are obtained. And the evolution trend for the soil pollutants are made known through a study of the concentration history of the pollutants in soil. The study demonstrates that the soil pollution courses may fall into two stages of acceleration and uniformity. Through the search after the historical time of nil-pollution and in combination with modern geochemical investigation data,a mathematic model of precaution and prediction on heavy metal pollution of soils and a precaution and prediction mode on soil environment are established. The key factors affecting the soil quality and the infective factors for the soil pollution are raised in the text and it is concluded that the industrial activities are the major factors affecting the soil quality and the pollution of soil is an accelerated course.
