摘要
On the basis of discussing the positions and functions of soil and water in terrestrial ecosystem,the concept of soil and water ecology is put forward.It is thought that the integral concept of inseparability between vegetation and soil,water is an important feature of soil and water ecology.Meanwhile,a new definition for soil and water ecological conservation is given,and it is divided into four types:ecological,natural,production and construction.At the height of soil and water ecology,it is an active,organic and holistic concept of soil and water conservation,and is deepening and development of the cognitive view on soil and water conservation to understand and control soil and water loss from the source and linkage of elements,which will make soil and water ecological conservation enter a new era.
