水电规划对四川宁南俱乐河流域两栖爬行动物的影响及对策

On Influence of Hydropower Planning on Amphibians and Reptiles in Ningnan County of Sichuan Jule River and its and Countermeasures

四川宁南县俱乐河流域近期被国家批准进行水电规划,为此我们对该流域的两栖爬行动物作了专项调查。采用线路统计法,统计与分析采集的数据。结果表明,该流域共发现两栖爬行动物3目14科26种,其中两栖类动物有2目9科14种,爬行类动物1目5科12种;该流域内两栖爬行动物均为东洋界种类的分布,分布类型以喜马拉雅-横断山区型为主。根据流域两栖类栖息的生态特点,其生态环境划分为流水、静水、陆地(含陆地-流水、陆地-静水)等,分布的种类较为均衡;爬行类栖息的生态环境划分为林地、灌草丛、田地等,其中灌草丛生态类型是该流域爬行类主要的分布区域。该文预测分析了该流域水电规划对两栖爬行动物的影响,提出了相应的保护对策。

A survey of amphibians and reptiles of Jule River in Ningnan County, Sichuaaa Province, owing to the recently State - approved hydropower planning, by using the line statistics and data on the basis of statistics and analy- sis, has been conducted. The results show, there exist 3 sections, 14 branches, and 26 species of amphibians and rep- tiles in this area, among which amphibians are 2 sections, 9 branches, and 14 species, and reptiles 1 section, 5branches, and 12 species, with the distribution of Indomalaya and its pattern of Himalaya - Hengduan Mountains. As to the eco - characteristics of amphibians, their distribution is balanced by classifying the eco - environments as run- ning water, still water, and lands including land - running water, land -still water） ; and forest land, shrubs, grasses and farmland for reptiles, and shrubs and grasses are the major. This paper forecasts the effects of hydropower planning to amphibians and reptiles in this area. outs forward relevant countermeasures.
