文摘Any ecosystem is commonly composed of organism and environmental system. Vegetation is primary producer and key factor of biological system,while water and soil are leading factors of environmental system. How to conform to and use nature,protect the integrity and continuity of the ecosystem,play ecological service function of the system,protect and improve eco-environment needs grasping key factor of ecosystem or principal contradiction,namely water,soil and vegetation.
