广西5个自然保护区两栖动物多样性分析

为分析广西5个自然保护区两栖动物的多样化程度，监测保护区的生态环境质量，根据广西5个自然保护区的两栖动物名录，通过物种组成比较并运用G-F指数进行科属阶元的多样性测度分析，结果表明：元宝山、猫儿山、岑王老山、弄岗、龙滩自然保护区的两栖动物G指数（DG）、F指数（DF）、G-F 指数（DG-F）分别为2.8144、3.9577、0.2889、2.8521、3.9831、0.2840、2.5709、3.5835、0.2826、2.5383、3.4516、0.2469，2.2481、2.2691、0.0093、较好地反映出广西5个自然保护区的两栖动物的科属阶元的多样性程度，为保护区的生物多样性保护与建设提供了依据。

Diversity of amphibian in 5 nature reserves in Guangxi

In order to further analyze the diversification of amphibian in 5 natural reserves in Guangxi and monitor the ecological environment of the conservation, based on the list of amphibian in the 5 natural reserves in Guangxi, family, genus and species of amphibian were analyzed by Sorenson index and G-F index. The result showed that, the G-index (DG), F-index (DF) and G-F index (DG-F) in Yuanbaoshan Natural Reserve, Maoershan Natural Reserve, Cenwanglaoshan Natural Reserve, Nonggang Natural Reserve and Longtan Natural Reserve were 2.8144, 3.9577, 0.2889; 2.8521, 3.9831, 0.2840; 2.5709, 3.5835, 0.2826; 2.5383, 3.4516, 0.2469, 2.2481, 2.2691, 0.0093, respectively. The results well reflect the family and genus diversity of amphibian in the 5 natural reserves in Guangxi, and provide basis for biological diversity conservation and construction in the 5 natural reserves.
