污染土壤生态修复研究进展（Advances in ecological remediation of contaminated soil）

污染土壤生态修复研究进展（Advances in ecological remediation of contaminated soil） Abstract: the research progress of ecological remediation of contaminated soil is introduced, analyzes the basic principle of ecological remediation of contaminated soil, the content and characteristics of repair repair, finally pointed out the prospect of ecological remediation of contaminated soils. Key words: contaminated soil; ecological restoration; heavy metal pollution; organic pollution Soil is the material base for human survival, and it is an indispensable and nonrenewable natural resource for human beings [1]. With the continuous infiltration of oil, city garbage, industrial waste, pesticides, fertilizers, soil pollution in China is becoming more and more serious, sustainable development has been a serious threat to the survival of the human environment and agriculture, become the water pollution, air pollution, noise pollution and solid waste pollution after the pollution problem has been one of the social widespread attention. According to incomplete statistics, at present, Chinas farmland contaminated by various pollutants has aboutHm2, accounting for about 10% of the total cultivated land area in the country, which seriously threatens human life and health. It is necessary to strengthen the cultivation of soil fertility, control soil pollution and clean soil pollution. In recent years, the ecological remediation technology of soil pollution has become a very active research topic both at home and abroad. Compared with the traditional physical remediation and chemical remediation, ecological remediation has the characteristics of high efficiency, no two pollution and simple operation. It has been gradually recognized by all of us, [2]. In this paper, the ecological remediation technology of contaminated soil was introduced comprehensively, in order to provide a useful reference for scientific researchers devoted to this field. 1 basic principles of ecological remediation of
