摘要: 目前生态网络构建研究中存在多种生态源地识别方法。深入研究不同生态源地识别方法对构建具有可对比性的生态网络结果、影响及其适用性具有重要意义。本文以渭河流域为例,基于遥感生态指数、生态系统服务、形态学空间格局分析、生境质量4种生态源地识别方法及其不同组合方式(共计15种)提取生态源地,并采用秩和比法对不同生态源地识别方法构建的生态网络进行评价。结果表明,利用不同生态源地识别方法构建渭河流域生态网络时:①基于生境质量识别的生态源地数量最多,而综合4种方法所识别的生态源地面积最大;②基于生态系统服务+生境质量的方法识别的生态廊道数量最多,而基于生境质量方法生成的生态廊道的总长度最长;③基于生态系统服务+生境质量的方法构建的生态网络表现最优。本文为构建统一的、可对比的生态网络结果提供了方法论基础。

Abstract: Currently, there are various methods for identifying ecological sources in ecological network construction research.In-depth research on different ecological sources identification methods is of great significance for constructing comparable ecological network results, as well as understanding their impact and applicability.This study takes the Weihe River basin as an example, utilizing four ecological sources identification methods—remote sensing ecological index, ecosystem services, morphological spatial pattern analysis and habitat quality—along with their various combination approaches (totaling 15 methods)to extract ecological sources.The rank sum ratio method is employed to evaluate the ecological networks constructed using different ecological source identification methods.The results indicate that when constructing ecological networks in the Weihe River basin using different ecological sources identification methods:①The method based on habitat quality identifies the largest number of ecological sources, while the method combining all four methods identifies the largest ecological sources area;②The method based on ecosystem services+habitat quality identifies the largest number of ecological corridors, while the method based on habitat quality generates the longest total length of ecological corridors;③The ecological network constructed using the ecosystem services+habitat quality method performs the best.This study provides a methodological foundation for constructing a unified and comparable ecological network.

Key words: ecological source, remote sensing ecological index, ecosystem services, habitat quality, Weihe River basin
