土壤生态研究的展望

Prospects for soil ecological study.

土壤生态研究是从生态学的观点出发,在对土壤的本质属性和独特运动规律作出更好揭示的基础上,阐明土壤作为陆地生态系统和整个生物圈中的中心环节的独特作用和功能,研究建立高生产力和洁净的陆地生态系统所需的优化土壤条件并拟定相应的有效措施,以更好地发挥土壤的生产潜力和改善人类的生存环境。其主要研究内容应包括:土壤肥力与状态因子的关系;土壤库在物质和能量的流动与转化中的作用;土壤生产力;土壤相对平衡地位的建立与保持以及方法学问题。

Soil ecological study is from the viewpoint of ecology and on the basis of further revealing the essential attribution of soil and its unique development patterns, to expound the distinctive role and function of soil as the key link of terrestrial ecosystem and whole biosphere, to study the optimum soil condition needed for constructing a terrestrial ecosystem with high productivity and little trouble with pollution, and to work out corresponding effective measures. The aim of these is to further give full play to soil's productive potentiality and improve mankind's existence environment. The main contents of soil ecological study should include: relationship of soil fertility with state factors; role of soil pool in matter flow and energy transformation; soil productivity; establishment and maintenance of relative equilibrium position of soil and problems of methodology.
