宁夏罗山国家级自然保护区兽类区系和生态分布

摘要

2010年10月至2011年12月，采用样线调查法和访问调查法对罗山自然保护区的兽类进行了综合科学调查，同时结合有关资料，对该地兽类区系特征及生态分布进行了研究。共调查到罗山有兽类36种，隶属6目14科31属，其中啮齿目种数最多，有15种，占保护区兽类总种数41．67％。根据区系特征，罗山36种兽类动物中，古北界种类25种，东洋界种类3种，广布种类8种。根据中国动物地理区划，可以看到罗山兽类动物含华北区的跨区区型有3（）种，复计比重达83．33％，说明罗山兽类动物区系和华北区区系关系更为紧密。罗山兽类生态分布分析表明，生境类型中山地荒漠草地分布的种类最多，有26种，占保护区兽类动物的72．22％。%A comprehensive scientific investigation was conducted on the mammals in Luoshan National Nature Reserve using line transect method mad survey method during October, 2010 to December,2Oll.The fauna characteristics and ecological distribution of mammals in the area were researched based on the investigation and relevant data. A total of 36 species belonging to 6 orders,14 families and 31 genera were recorded. Among the mammals, the dominant groups are Rodentia(15 species,41.67% of the total). Among 36 species of the mammals in the Lushan area, 25 species belong to the Palearetie realm,3 species (8.33%) belong to the Orienial realm and 8 species (22.22%) are widely distributed species. According to the animal fauna of China, among the mammals in the Luoshan area, 30 species are North China cross zone type, the proportion of repeat counting reaches 83.33%. it shows that the fauna composition of mammals in Ningxia Luoshan area is more closely related to North China fauna. The analysis on ecological distribution of the mammals in Luoshan area shows the highest mammals species number is in mountain desert grassland (26 species),accounting for 72.22% of the mammals in Luoshan National Nature Reserve as far known.
