        论述了新世纪中国土壤学的社会需求,提出食物安全仍然是土壤学要关注的首要问题。食物安全所包括的数量安全、质量安全、经济安全和生态安全都与土壤质量和土壤利用直接相关。提出了我国土壤学在今后要关注和试图解决的几个科学问题:(1)土壤质量新概念的建立;(2)土壤圈与其它圈层的物质和能量交换理论;(3)可变电荷土壤特性;(4)土壤高强度利用与环境协调理论。

        Social demand and development of soil science in China in 21st century is briefly demonstrated in this paper. Food Security including quantity, quality, economy, and ecology security for food production is believed to be closely related to soil quality and soil utilization. Chinese soil scientists should pay more attention to the following aspects to promote the development of soil science:(1)new concept of soil quality; (2) theory on exchange of matter and energy between pedosphere and atmosphere, hydrosphere, lithosphere, and biosphere;(3)Characteristics of variable charge soils; (4) Theory on intensive use of soil and environmental production.
