摘要：

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.
