Soil-ecosystem has done much with the stability of agriculture,recently the facts influencing the function of soil-ecosystem were not restricting in polluting from physical or chemical sources,the GM technic applying in agriculture not only made the pumping harvest in agriculture,but produced the more serrious harm: transgenic bio-pollution.

Progress of transgene crop gene floating and it s gene pollution;

s: In this paper, the possible influence of genetic pollution on ecological and environmental safety was discussed, and the serious of genetic pollution also analyzed from different point of view.

At the time biosafety of genetic engineering has aroused more and more concern,organic agriculture,as a new industry,is inevitable exposed to the impact of geneflow and gene contamination.

Because in modern transgenic technology the benefit side coexists with the danger side,more than 70 countries (including the People s Republic of China) signed "The Protocol of Biosafety" in order to prevent the endanger of gene contamination,and to protect the diversity of biology.

Influences of genetically modified organisms on biodiversity;

Commentary on the legal system supervision to environment caused by genetically modified organisms under the ecological civilization background;

Development status of genetically modified organisms were reviewed,potential biological safety problems of genetically modified organisms were introduced,their possible hazards and risk were appraised,and some countermeasures are provided to solve the potential safety problems to develop genetically modified organisms in China.
