【摘要】 通过对被保护物种生存环境的分析是探知该物种灭绝和种群数量下降的重要手段.2002年9月间,作者在参加南陵县野生扬子鳄栖息地生境的考察工作的基础上,以安徽省南陵县野生扬子鳄生存环境作为对象,对野生扬子鳄的生存的环境因素进行分析评价.结果表明,影响野生扬子鳄生存环境质量的主要因素为食物、隐蔽条件和水体以及人的活动.在安徽省南陵县二个官方指定的保护点中长乐点尽管食物、隐蔽条件和水三大生境基本要素都较为理想,但因为没有足够的栖息地因此这里并不适合野生扬子鳄种群的生存.比较而言,如对楂林点野生扬子鳄的生存环境进行一定的人工修饰,此地应该有着较为合适的生存环境.更多还原

【Abstract】 The survival environment analysis to protected species is the important means to detect the population decline and extinction reasons. A field survey on wild Chinese Alligator habitat was conducted in Nanling County, Anhui Province in September 2002. This paper analysed the survival environmental factors of the wild Chinese Alligator in Nanling County, Anhui Province. The results showed that the food ,concealment, water and human actions are the important factors. Changle point in Nanling County, Anhui Province has ideal survival environmental factors. But it too small for Chinese Alligator population. comparatively Zhalin point is the good place for Chinese Alligator.更多还原
