摘　　要：鉴于高原山地的特殊地理环境及社会经济条件的限制,高原山地区域目前面临着城市快速扩张、生态保护压力大等挑战。以高原山地地区的云南省镇沅彝族哈尼族拉祜族自治县为例,结合生态系统服务功能重要性评估和形态学空间格局分析,从功能性和结构性2个方面综合确定生态源地,并利用电路理论原理构建生态廊道,进一步识别生态夹点和生态障碍点,构建生态网络,最后根据各乡镇发展现状提出针对性建议。结果表明:镇沅县拥有生态源地21个,形成生态廊道38条,共识别出夹点区域23.31 km^(2)以及障碍点区域40.00 km^(2)。生态源地及廊道多分布在镇沅县西部,而东部存在明显的断层现象。最后基于各乡镇发展现状条件与发展愿景,综合构建了镇沅县“四区、一轴、六脉、多廊道、多节点”的生态网络体系,并提出各乡镇未来发展重点及方向。In view of the special geographical environment and socio-economic conditions of the plateau mountainous area,the plateau mountainous area is currently facing challenges such as rapid urban expansion and high pressure on ecological protection.Taking Zhenyuan Yi and Hani and Lahu Autonomous County of Yunnan Province in the plateau mountainous area as a case study,this study integrates ecosystem service importance assessment with morphological spatial pattern analysis to comprehensively identify ecological sources from both functional and structural perspectives,and construct ecological corridors using circuit theory.Furthermore,identify ecological pinch points and ecological obstacle points,build an ecological network,and finally put forward targeted suggestions based on the development status of each township.The results show that Zhenyuan County contains 21 ecological sources and 38 ecological corridors.A total of 23.31 km^(2)of the pinch area and 40.00 km^(2)of the obstacle area are identified.The ecological sources and corridors are mostly distributed in the west of Zhenyuan County,while there are obvious faults in the east.Finally,based on the development status and development vision of each township,the ecological network system of'four districts,one axis,multiple corridors and multiple nodes'in Zhenyuan County was comprehensively constructed,and the future development focus and direction of each township were proposed.
