Abstract

With the advance of biodiversity and landscape research，the studies on edge effect has enter a new phase since the concept of edge effect came into being，and the study on the response of creature to edge effect has become a hot research topic too. Grasshopper as one group of the important insects，the study on the edge effect would help us to grasp their distribution patterns precisely and hence offer some of basic theory on the analysis on grasshoppersedge response and its intensity . Four types of edge zones：farmland-grassland，farmland-shrub，farmland-road，and grassland-road，were selected and analyzed based on ecological characteristics of the North-Luo River Valley of Yanan using the Shannon-Wiener biodiversity index（H），Pielou index（J），Simpson index（C）and species quantity. Results showed that both species quantity（25 species） and H of 2.574 5 for the grassland-road treatment were highest. Edge effects with four edges for the farmland-shrub treatment was below 1 （0.916 0）；whereas the other three treatments had positive effects（＞ 1）. Thus，for effective grasshopper prevention and control，edge effects should be considered as an important factor so as to combine different types of grasshoppers to different edge types.［Ch，1 fig. 2 tab. 20 ref.］
