生态边缘效应与生态平衡变化方向

摘要/Abstract

关键词: 土地利用方式, 赤红壤, 土壤微生物, 土壤酶活性, 土壤肥力

Abstract: Human activities produce inany ecosystems which form new edges with original ones.On the other hand, the edge effects also change the quality of ecosystems. The new edge effects will show positive or negative ecological effect on the original ecosystems, which is named as edge effect directivity.Therefoe that human activities can affect the change directions of ecosystem quality with edge effects. It is important to study to the edge effect and the change direction of ecosystem balance,so as to regulate and control the ecosystems wisely.

Key words: land use type, lateritic red soil, soil microbe, soil enzyme activity, soil fertility.
