The basic principle of bioremediation that for special contaminated site different treatment techniques were selected on three factors which are decrease the toxicity of pollutants and increase the bioavailibility of pollutants and the bioactivity of microorganisms.

This provides a method for extracting energy from organic matter,and helps to promote the bioremediation of organic contaminants.

This paper reviews the sources of laccase,including animal,microorganisms and plants especially those originated from Rhus vernicifera trees and other related plants in China,the stabilization and immobilization of enzymes,its green chemical applications on bioremediation,lignin biodegradation/biosynthesis and other various aspects.

Eco-environmental fragility in Guizhou Karst mountain region and its ecological rehabilitation.;

This article puts forward an agricultural ecological renovation strategy for using polluted cropland in high efficiency.

From the perspective of contrasting the economic and environmental construction between district of inner city and the rural -urban fringe,combining a case from Qingshui River in Chengdu city,it probes the importance of ecological renovation of small watershed in rural-urban fringe.

Investigation of the characteristics of multi-phase rupture destructive action and emulation on the regulating structures at mountain ous rivers;

Due to their advantages,the permeable regulating structures are used gradually for river regulation now.

On the basis of analyzing the characteristics of incoming flow and sand,pattern of sediment deposition and feature of obstructing navigation of Chishui River,It s proposed that the width of the silting-up reach be restricted by means of regulating structures,reef explosion and dredging,which was proved from model test.
