三江源国家公园黄河源园区与周边社区生态风险治理研究——以玛多县为例

RESEA RCH ON ECOLOGICAL RISK MANAGEMENT OF THE THREE-RIVER-SOURCE NATIONAL PA RK AND IT'S SURROUNDING COMMUNITIES BY THE CASE OF MADUO COUNTY

生态风险是人类活动对生态环境造成的破坏,危害可持续发展与社会经济健康运行。以地处三江源国家公园黄河源园区腹地的玛多县为研究对象,利用PSR模型构建生态风险评价体系,结果显示:在2014~2021年期间,该地区的生态风险指数呈现先升高后持续下降的特点,由2014年的3.10上升至2016年的3.67到达峰值,随后逐年下降,至2021年生态风险指数降至0.67。分析发现,生态风险的持续下降与政策驱动关系紧密。对此,提出发挥党在生态风险治理中的核心地位、构建生态绩效考评机制、大力发展集约畜牧业村镇集体经济、加快生态风险治理多元主体转型的政策建议.

Ecological risk is the destruction of ecological environment caused by human activities,which endangers sustainable development and the healthy operation of social economy.Takingmaduo County,located in the hinterland ofhuangheyuan National Park,as the research object,the PSRmodel was used to buildan ecological risk assessment system.The results showed that during 2014 to 2021,the ecological risk index of this area increased first and then continued to decline.From 3.10 in 2014 to 3.67 in 2016;Then,the ecological risk index dropped to 0.67 by 2021.It is found that the continuous decline of ecological risk is closely related to policy driving.In this regard,the paper puts forward some policy suggestions to give full play to the Party's core position in ecological riskmanagement,construct ecological performance evaluationmechanism,vigorously develop the collective economy of intensive animal husbandry villages and towns,and accelerate the transformation ofmultiple subjects in ecological risk management.
