中文摘要:
      [目的]评价河南省淅川县是丹江口水库核心水源区生态安全状况,旨在为保障南水北调中线工程功效长久发挥提出相应的调控措施。[方法]以淅川县各乡镇为评价单元,利用改进"PSR"模型、层次分析法和GIS技术,进行淅川县生态安全时空演变规律研究,并运用主成分分析法研究了淅川县生态安全主要驱动因子。[结果]①淅川县生态安全状况虽有波动但整体好转。与2000年相比,2015年中警和预警状态的乡镇各减少了3个,而较安全状态的乡镇增加为6个。②淅川县生态安全空间格局呈东北、西南等级较高,西北、东南等级较低的态势。③通过驱动力分析发现淅川县生态安全等级提升的主要原因为积极的环境治理响应。[结论]生态安全的良性转变需通过积极引导人类活动,多筹举措共同作用促进区域生态安全和社会经济的可持续发展。
英文摘要:
      [Objective] To evaluate the eco-security status in Xichuan County of He'nan Province, the core water source area of Danjiangkou reservoir, in order to put forward corresponding control measures to ensure the long-term performance of the middle route of south-to-north water diversion project. [Methods] Based on the improved PSR(presure-state-response) model, AHP (analytic hierarchy process) and GIS technology, the temporal and spatial evolution of ecological security in Xichuan County was evaluated. The main driving factors of ecological security in Xichuan County was analyzed by principal component analysis. [Results] ① The eco-security situation of Xichuan County fluctuated, but overall improved. Compared with 2000, the towns with medium and primary warning were reduced by 3, while the towns with the relatively safe increased by 6 in 2015. ② The spatial pattern of eco-security in Xichuan County was higher in the northeast and southwest, but lower in the northwest and southeast. ③ According to the driving force analysis, it was found that the main reason for the improvement of eco-security level in Xichuan County was the positive response of environmental governance. [Conclusion] The benign transformation of ecological security needs to promote regional eco-security and sustainable socio-economic development by actively guiding human activities and multi-raising measures.
