摘要
通过研究崇礼区生态敏感性,探究崇礼区生态系统内部环境对于人类活动干扰的敏感程度.利用地理信息系统(GIS)技术对崇礼区生态环境进行分析,选取高程、坡度、坡向、水域缓冲区、植被覆盖率和土地利用类型 6 个评价指标,运用层次分析法、熵值法、综合赋权法和GIS空间分析法,构建指标体系并进行生态敏感性综合评价,得出崇礼区敏感性主要集中在不敏感和轻度敏感区域的结果.在未来发展中崇礼区需要针对不同的生态敏感性分区提出不同的保护和利用策略,同时需要发挥区域内的生态环境优势,扬长避短,实现崇礼区土地资源合理利用及生态与社会及经济的高质量发展.
Abstract
Through the study of the ecological sensitivity of Chongli District,this research aims to ex-plore the degree of sensitivity of the internal environment of the Chongli District ecosystem to hu-man activities,providing an important theoretical basis for the optimization and construction of the ecological environment in Chongli District.Utilizing Geographic Information System(GIS)technol-ogy,an analysis of the ecological environment in Chongli District is conducted.Six evaluation indi-cators,including elevation,slope,aspect,water buffer zone,vegetation coverage,and land use type,are selected.The Analytic Hierarchy Process(AHP),Entropy Method,Comprehensive Weighting Method,and GIS spatial analysis method are employed to construct an indicator system and con-duct a comprehensive evaluation of ecological sensitivity.The results indicate that the sensitivity in Chongli District is mainly concentrated in non-sensitive and mildly sensitive areas.In future de-velopment,Chongli District needs to propose different protection and utilization strategies for dif-ferent ecological sensitivity zones,while leveraging the advantages of the regional ecological envi-ronment to achieve sustainable and high-quality development of land resources,ecology,society,and economy in Chongli District.
