摘  要：
2005年10月,采用铗日法对四川九顶山自然保护区的小型兽类进行了调查,共捕获小型兽类12种112只。根据植被状况把保护区的小型兽类划分为4个群落类型。通过各种小型兽类捕获率和所占总数比例分析出各群落内的优势种,利用相关分析得出个群落间的相似性;根据Shannon-Wiener指数分析了群落的多样性和均匀性,得出以下结论:保护区内的小型兽类中,社鼠、四川短尾鼩和龙姬鼠为群落中的优势物种;在人工林,人工+次生混交林以及次生天然林中,小型兽类物种相对丰富,而在海拔较高的高山灌丛中相对较少;人工+次生混交林的多样性最高,次生天然林的均匀度最高,这两种生境群落的相似度最高,反映出该区域的植被恢复较好,人工与天然林混交的造林方式也能较好的维持当地的生物多样性。

摘  要：
In October 2005,an investigation was made on small mammals in Jiudingshan Nature Reserve,Sichuan Province.112 individuals were captured,belonging to 12 species.According to the conditions of the Reserve,we divided the small mammals into four community types.By calculating the capture rate and the proportion of the captured,we can find out the dominant species of various communities,and correlation analysis could show the similarity between the communities;the Shannon-Wiener index would show the community diversity and uniformity.At last we drew the following conclusions: among the small mammals in the Reserve,Apodemus draco,Niviventer confucianus and Anourosorex squamipes were the dominant species in the community;in the artificial forest,artificial and secondary mixed forest and secondary natural forests,small mammal species were relatively abundant,however,were relatively scarce in shrubs in higher altitudes.The artificial and secondary mixed forest had the highest diversity index,and the secondary natural forest had the maximum uniformity.These two kinds of communities had the highest similarity among the four,which reflected that the restoration of vegetation in this region was well,and the pattern of artificial and natural mixed forest could be a better way to maintain local biodiversity.
