摘要：在对黄河上游四川段水源涵养功能及修复潜力评估的基础上,利用形态学空间格局分析法(MSPA)识别黄河上游四川段生态源地,运用最小累积阻力模型识别生态廊道.结果表明:整个研究区水源涵养能力由南至北逐渐降低,水源涵养修复潜力等级高的区域主要分布在研究区域北部;MSPA识别的核心区主要位于若尔盖县和石渠县,占总面积的44.04%,形成由3个等级的生态源地和3个等级的生态廊道组成的黄河上游四川段生态安全格局;整个生态网络均集中于研究区中北部,东西部和南部生态网络分布较少.基于生态网络进行生态安全格局的构建,可为黄河上游四川段水源涵养生态修复布局提供重要依据.
Based on the assessment of the water conservation service function and its restoration potential in the upper reaches of the Yellow River(Sichuan section),the Morphological Spatial Pattern Analysis method(MSPA)was utilized to identify the ecological source areas in the upper reaches of the Yellow River in Sichuan.The Minimal Cumulative Resistance model was applied to recognize ecological corridors.The results indicate that the water conservation capacity of the entire study area gradually decreased from south to north,the areas with high potential for water conservation restoration were mainly in the northern part of the study area.The core area identified by MSPA was mainly located in Ruoergai county and Shiqu county,accounting for 44.04%of the total study area.The ecological security pattern of the upper Yellow River in Sichuan consisted of three levels of ecological source area and three levels of ecological corridor.The entire ecological network was concentrated in the central and northern parts of the region,Ecological networks in the east,west and south were rather sparse.The ecological security patterns derived from ecological network provide important guide for the layout for water conservation ecological restoration in Sichuan section of the upper Yellow River.
