In this paper,the references between Genetic Soil Classification of China(GSCC) and the Chinese Soil Taxonomy(CST) for GSCC-Semi-Luvisols were conducted,and their quantitative and spatial distribution characteristics within CST were studied,based on the 1∶1 M Soil Database of China,which consists of 1∶1 M digital soil map,soils profiles attribution database and soil reference system of China.

Derivation and verification of soil hydrodynamic parameters in cinnamon soil;

In this paper, a series of laboratory experiments, including batch equilibrium experiment, soil column leaching experiment and soil degradation experiment, have been adopted to scrutinize the transport behaviors of five Pyrethroids includes cypermethrin, decamethrin, .

Based on analysis of the characteristics of the tea garden soil in the limestone region in Chizhou City and in line with the Catalogue of the Chinese Soil Taxonomy, the soils in this region are divided into three orders: Luvisols, Ferrisols and Cambisols, thus clarifying the misunderstandings about cultivation of tea in the limestone region.

2 soil profiles of them belonged to black Lithologic Isohumisols group, l soil profile to cab-Udic Luvisols group, and 5 soil profiles to cab-Udic Cambisols group.
