摘要：

以PSR（压力-状态-响应）模型为基础，开展了阿尔金山自然保护区草地生态安全量化研究。结果表明：阿尔金山保护区内高寒草甸、高寒垫状植被、高寒荒漠、高寒草原的生态安全大小分别为3.105，2.805，2.474和1.942，分别处于很安全、基本安全、基本安全和较危险状态。保护区全区草地生态安全整体处于较安全状态，试验区生态安全程度最高，缓冲区生态安全程度最小。

Abstract:

In this study, we analyzed the status of eco-security of Altun Mountain nature reserve applying the multi-index comprehensive assessment method on the basis of PSR (pressure-state-response) model. The results indicated that eco-security index of different ecosystems was 3.105, 2.805, 2.474 and 1.942, respectively, in the order of alpine meadow >alpine cushion-like vegetation >alpine desert >alpine grassland. They were defined in highly safe, basically safe, and slightly dangerous status. On the whole, the eco-security of nature reserve situated basically safe status. The proportion of safe areas was larger in the experimental zone than that of core area, and it was the lowest in buffer zone.

Key words: Eco-security assessment, Functional zone, Grassland ecosystem, Altun Mountain National Nature Reserve, PSR model
