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。

摘  要:
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.
