Abstract:
Neighbor diversity and interspecific association of Quercus mongolica were studied through point sample method. With the increase of plots number, species richness and Shannon-Wiener (H') diversity index increased. At last they came close to fixed value. LS value (average number of neighboring species) was first introduced in this article. Different sits had different PC value (value of interspecific association). According to PC value and LS value, accompany tree and shrub species of Quercus mongolica were determined. The similar environmental requirement and mutualism were the main reason why they live together. The result of interspecific association between Quercus mongolica and other species in 4 locations was analyzed. The reason why the differences existed was that Quercus mongolica studied was in different succession stages.
