Understanding sustainability of soil and water resources in a critical zone perspective

Soil and water resources are fundamental for human beings.Understanding the status and the evolution of regional water and soil resources is the prerequisite for their sustainable management.China is severely constrained by water and soil resources which are subject to soil forming processes under different natural factors such as climate and relief,and also influenced by diversified landuse histories and intensities.Quality and security of water and soil resources are therefore influenced by both natural and anthropogenic processes.
