该文对南充市金城山不同生境中小型兽类群落结构和多样性进行了初步研究。在4种不同生境类型中共捕获小型兽类标本528只，共12种。采用Shannon-Wiener多样性指数、均匀性指数、生态优势度指数和物种数对4种生境中捕获的小兽进行了分析，结果表明，4种不同生境的小型兽类群落Shannon-Wiener多样性指数在0.5704～1.0198；均匀性指数在0.3301～0.6337；Simpson生态优势度指数在0.433～0.738。不同生境条件的差异对小型兽类群落物种组成和多样性有一定的限制作用，而人类活动干扰对其也有较大影响。

The diversity and species component of small mammal communities were measured with trap-day method in Jincheng mountain of Nanchong city. A total of 528 individuals were captured and twelve spe?cies of small mammals were recorded. The results of analysis on diversity of small mammal communities showed that Shannon-Wiener diversity index was 0.570 4~1.019 8;evenness index was 0.330 1~0.633 7;Simpson dominance index was 0.433~0.738. The diversity and species component of small mammal commu?nities were determined by the difference of habitats and affected by human activities.
