徐州石灰岩山地不同经营强度人工林群落的植物多样性研究
Species biodiversity of plantation communities under different management intensity in the limestone hill region of Xuzhou city
摘要
Abstract
Oriental arborvitae (Platycladus orientalis Franco) plantation communities in Quanshan nature reserve, a typical limestone hill region in Xuzhou city, were surveyed with stratification method. Species biodiversity of plantation communities under three different management intensities were calculated, using Patrick,Simpson, Shannon-wiener and Pielou indexes. Results showed that the region with high strength management has the highest plant diversity. The dominant species had naturally converted from oriental arborvitae community with an importance value of 23.59 to black locust (Robinia pseudoacacia Linn. ) community, of which importance value was 44.28. In contrast, the lower plant diversity was found in Yunlongshan community with middle management intensity, and the lowest occurred in Xiaotaishan community with weak management intensity. In addition, the plant diversities in different stratification took on an increasing trend from top and ground layers to middle layer for each community.关键词
