Abstract:

Soil erosion has caused the a ttention of the whole world, and the paradigm of soil erosion control is the hotspot in the research of water and soil conservation. This paper introduces the process of the paradigm in science research and the effect on soil erosion control. And same time, the relationship between paradigm of soil erosion control and ecological paradigm was discussed. It also showed that ecological theory has important effect on soil erosion science, and ecological factor has to be considered in the research of soil and water loss control. There is an interactive relationship between process of soil erosion and ecology, which is coupling relationship in supplement each other. Some theories in ecology, such as natural equilibrium theory, systemic nonequilibrium theory and hierarchical patch dynamics theory have profound effect on the development of soil erosion science, and been put in practice in to some extent. Ecological environment balance theory must be emphasized on the research of soil erosion control.

Key words: agroforestry, ecology, paradigm, soil erosion
