Abstract:

In order to research the dynamic stability of Quercus aliena var. acuteserrata community in Xiaolong national nature reserve, as well as the different natural conditions and the relationship between communities, based on the implementation of ‘Tianbao project’, the author investigated the species diversity and stability of the quercus aliena var. acuteserrata community. The conclusions were as followed: (1) Patrick abundance index R was 10.6, Shannon-Wiener index H′ was 1.4222, Pielou index Jsw was 0.5450, Simpson index C was 0.413; (2) Through the comparison between herbs layer, shrub layer and the tree layer: for the diversity index, the shrub layer was greater than the herb layer, while was larger than the tree layer; for the uniformity index, the herbs layer was larger than the shrub layer, while was larger than the tree layer; (3) Within the region, the diversity index was decreasing with the increasing elevation, but the abundance index changes; (4) The Quercus aliena var. acuteserrata community, which was built with Quercus aliena var. acuteserrata species, which belonged to be stable. Compared with the earlier studies, the results proved that the implementation of ‘Tianbao project’ was scientific and effective. The survey provided the basic data for the delimitation in the Quercus aliena var. acuteserrata areas of Xiaolong mountain and regional environmental management.
