基于功能性连接度的相关理论,以长沙市宁乡县中心城区为研究区域,以灰椋鸟Sturnus cineraceus为城区鸟类的指示物种,采用连接度指数IIC、PC对研究区域现有林地网络的功能性连接度进行分析,并选取11个核心林地斑块和15个重要林地斑块,11条核心飞行廊道和16条重要飞行廊道;再利用最小累积阻力模型对林地斑块及斑块间的连线进行分析,识别出不利于灰椋鸟进行生态扩散过程的林地斑块及飞行廊道:核心林地斑块中斑块31、斑块43受中度干扰,核心飞行廊道中廊道50-42、廊道28-3处于中度阻碍状态,在今后进行城市生态格局规划时需对其进行优化。

The habitat fragmentation of current urban ecological structure and the disturbance on native species are increasingly severe along with urban development. Therefore,it is obviously significant to analyze and integrate the urban ecological network by testing the functional connectivity of special species which can provide theoretical basis for the solution to the fragmentation of landscape space type and enrichment of landscape space heterogeneity,as well as technical guidance and reference basis for the optimization of landscape space pattern. Moreover,these can also contribute to the underst...
