洞庭湖湖滩小型兽类种群暴发与群落演替的分析和启示
Analysis and Implications of Population Outbreaks and Community Succession of Small Mammals on the Beaches of Dongting Lake
摘要
Abstract
The beaches of Dongting Lake are a special habitat type.Due to fluctuating water levels,the small mammals inhabiting the lake beaches are forced to move out during the flood seasons and naturally return after the water recedes,forming a distinct community that differs from those in surrounding habitats.Specifically,the Yangtze vole(Alexandromys fortis)exists as the overwhelmingly dominant species on the lake beaches.Before the 1970s,there were no large-scale outbreaks of voles.However,between the 1970s and the 1990s,the vole population exploded and caused disasters,and in 2007,a severe vole outbreak escalated into a disas-ter.Research indicates that this event resulted from the coincidence of a peak year in vole population fluc-tuation with human activities that favored their population growth.After the implementation of the Three Gorges Project,other small mammals from surrounding habitats extensively invaded the lake beaches,espe-cially large numbers of Apodemus agrarius,reflecting the subversive impact of human social and economic activities on the succession of animal communities.Therefore,the community succession and population de-velopment of small mammals in the Dongting Lake beach habitat exemplify the social-economic-natural complex ecosystem theory.关键词
