PROTECTION AND USE OF SOIL RESOURCES AND CONSTRUCTION OF AGRICULTURAL ECOLOGY

Xu Qi, (Institute of Soil science, Academia Sinica, Nanjing)  
Soils that grow in different natural environment have different soil fertili-ty. From soil fertility evolutive mechanism, this paper expounds that if cropping system andsafeguardings are not rational, soil resources will degenerate. This paper also analyses the im-portance of our agricultural ecological construction, its content and its devolopmental direc-tion.
