摘要

目的

构建克里雅河流域的生态安全格局，为当地的生态安全格局优化、生态修复和生态保护体系的建立提供科学依据。

方法

以克里雅河流域作为研究对象，运用InVEST模型，对水源涵养、土壤保持、生境质量和碳储量等生态功能服务重要性进行量化评估；构建生态敏感性评价体系，评估研究区生态敏感性，以此确定生态源地的位置。借助最小累积阻力模型（MCR）构建生态阻力面，并借助ArcGIS软件识别生态廊道，最终构建研究区生态安全格局。

结果

克里雅河流域生态源地总2块，总面积为4 610.47 hm

，位于研究区中、南部林地、草地聚集分布的区域；生态廊道在促进物种活动，保持水土以及提升生物多样性等方面发挥着重要作用。生态廊道共3条，其长度分别为582.75，113.43和65.11 km。

结论

对于克里雅河流域生态环境而言，防沙治沙，以林养林极为重要。应合理支配水资源，选择适合防沙治沙的植物进行种植，建设沙漠绿洲并创造经济价值，为研究区生态修复提供经济支撑。

Abstract

Objective

The ecological security pattern （ESP） of the Keriya River basin was constructed to provide a scientific basis for optimizing ecological security， restoring ecosystems， and establishing ecological protection systems in the region.

Methods

Taking the Keriya River basin as a study area， the InVEST model was employed to quantitatively evaluate the importance of key ecosystem services， including water conservation， soil retention， habitat quality， and carbon storage. An ecological sensitivity evaluation system was developed to assess regional ecological sensitivity and identify ecological sources. A minimum cumulative resistance model was used to construct an ecological resistance surface， and ArcGIS software was applied to delineate ecological corridors， ultimately forming the ESP of the basin.

Results

The Keriya River basin contains two ecological sources， with a total area of 4 610.47 hm²， located in the forested and grassland regions in the central and southern parts of the basin. Three ecological corridors， with lengths of 582.75， 113.43， and 65.11 km， were identified. These corridors are crucial for facilitating species movement， conserving soil and water， and enhancing biodiversity.

Conclusion

Desertification control and sustainable forest management are paramount for the ecological environment of the Keriya River basin. Rational water resource allocation， the selection of vegetation suited for sand fixation， and development of economically valuable desert oases are essential to support ecological restoration and provide financial sustainability for the region.
