六盘山自然保护区两栖动物栖息地的重要性评判

The importance assessment of the habitat for ampibians in Liupanshan mountain nature reserve

根据2011—2014年进行的宁夏六盘山国家级自然保护区生态监测得到的该地区两栖爬行动物种类和数量数据,运用综合模糊评判法对保护区内的5个监测点进行了两栖爬行动物栖息地的重要性评价.评判中隶属度的确定采用最佳因子值法,并分春夏两个最佳因子值进行评判.结果表明,夏季各监测点重要性比春季高,因此夏季是管理的重点;无论春季还是夏季,在种类的多样性和物种的濒危保护价值方面,小南川监测点相较于其他监测点其重要性(0.764和0.966)最高,应给予重点管理;老龙潭、二龙河的结果相近,重要程度次之,可持有较高程度的管理水平;冶家村春季物种数量和多样性均较高,应给予一般水平的管理,凉殿峡的夏季物种多样性较高,但也只需一般水平的管理.

Based on the date of species and population,the ampibians habitat in Liupan mountain nature reserve of Ningxia province from 2011—2014is assessed in 5 wetland in the nature reserve by fuzzy synthetic method.The fuzzy membership function value is measured from the best value of factors.We deal with the date in two values,one is the maximum of springtide date,another is the maximum of summer date.The results are as follows：The amphibian habitat is more important in summer than that in springtide in all 5wetland,so springtide is a key period of the management of habitat.The Small south river wetland is the most important habitat of all both in springtide and summer,they are 0.764and0.966.In springtide for other wetland like Old drogon pool site and Two drogons river site,the results are similar,and positioned in the second most important habitat where equal attentions are required for management.In springtide,both the population and diversity of Yejia village site are high.In summer,the diversity of Cool palace canyon site is high.Routine management is enough.
