摘　　要：由于生态敏感性评价能够预测生态环境遭到干扰和破坏的程度,可为区域土地资源合理利用和生态环境保护提供依据。以长沙县湘丰村为研究对象,从地形地貌、生境资源和人类活动3个方面筛选8项影响因子并进行综合赋权,采用加权叠加法对长沙县湘丰村进行了综合生态敏感性分析并探究了其生态建设策略。结果表明:研究区整体生态敏感性较高,土地利用类型和植被覆盖度是其主要的敏感因素;高敏感区、较高敏感区、中度敏感区、较低敏感区和低敏感区分别占总面积的22.94%、23.27%、17.02%、19.19%、17.57%。该研究结果可为湘丰村土地资源合理开发利用提供科学依据,促进区域生态保护和经济发展双赢。The ecological sensitivity assessment can predict the extent of disturbance and damage to the ecological environment and provide a basis for the rational use of land resources and ecological environmental protection in the region.Taking Xiangfeng Village in Changsha County as the research object,eight impact factors were selected from topography and landform,habitat resources and human activities and assigned comprehensive weights,and the weighted superposition method was used to conduct a comprehensive ecological sensitivity analysis of Xiangfeng Village in Changsha County and explore its ecological construction strategy.The results of the study show that the overall ecological sensitivity of the study area is high,with land use types and vegetation cover being the main sensitive factors;22.94%,23.27%,17.02%,19.19%and 17.57%of the total area is highly sensitive,more sensitive,moderately sensitive,less sensitive and less sensitive respectively.The results of this study are intended to provide a scientific basis for the rational development and use of land resources in Xiangfeng Village,and to promote a win-win situation for both ecological protection and economic development in the region.
