Methodological systems of building agricultural soil quality criteria in China

The study on agricultural soil quality criteria is of great importance to the protection of agricultural soil resources, the safety of agricultural products and human health. In order to promote the systematic research on agricultural soil quality criteria at the national level, it is firstly impending to theoretically explore methodological systems of building-up agricultural soil quality criteria in China. Thus, on the basis of the researching progresses in soil-environmental criteria at home and abroad, including three main methods of establishing soil quality criteria, methodological systems of building-up agricultural soil quality criteria in China were in-depth discussed. Solutions to the application of basic methods, the selection of ecological receptors, the determination of assessment indexes and classificatory problems of soil types for deriving-up soil quality criteria in China were given and put forward. At last, researching directions on agricultural soil quality criteria with a particular emphasis on the methodologies and technical tips were also suggested.
