摘 要 ：利用多样性指数和种群动态相结合 ,建立竞争指数对小红珠绢蝶东灵山种群的濒危机制进行分析。结果表明 ,小红珠绢蝶的竞争指数在不同年份的下降过程中有不同的变化。以此为依据可以准确地判断出对该种群动态影响的环境因子。这一方法有很高的普适性 ,可应用于昆虫种群的保护生物学研究。

Abstract:Study on dangerous species‘ biology and population ecology is still a very important subject in biodiversity conservation research. However, there are few studies on internal mechanism between the protected species and the components of community, especially the synchronization of dangerous species population dynamics and fluctuation of concomitant species diversity. Caughley presented the common distinguish method and protect procedure of descending population (1994). He reported that the study of a descen...
