复杂地貌区域国土开发受生态环境因素影响较单一地貌地区更复杂，其境内生态敏感区类型较多，且空间分布比较杂乱，不同生态敏感区之间又相互影响。文章选择山、水、林、田、城互为镶嵌的广西钦州市作为案例城市，以小流域为评价单元，建立集“地”、“水”、“绿”三位于一体的评价体系，在遥感和GIS技术的支持下，将单因子定性分级和多因子空间叠加模型相结合，对整个区域的生态敏感区进行综合评价及分区。从研究结果来看，这种评价技术能够较好地反映这些生态敏感区的综合分异规律，有助于当地政府在区域开发中制定更为科学的生态安全防范对策。

Eco-sensitivity evaluation is the basis for land development and has practical significance to the establishment of environmentally-friendly economic and social development models. Compared to simple geomorphic regions, complex geomorphic regions are limited by a higher number of eco-sensitivity factors under a land exploitation context. Further still, these factors have complicated spatial characteristics and affect each other. Based on published data, we focused on the city of Qinzhou in Guangxi Zhuang Autonomous Region, China and developed an eco-sensitivity assessment system spanning land ecology, water ecology and plant ecology. A systematic comprehensive assessment of all watersheds was done using qualitative classification, spatial quantitative modeling, remote sensing and GIS technology. We were able to group Qinzhou’s 273 watersheds into three types: high sensitivity areas, medium sensitivity areas and low sensitivity areas. We propose a limit on land exploitation activities in high sensitivity areas and an ecological security network. The methods utilized here can help determine eco-sensitivity characteristics in complex geomorphic regions and with this knowledge governments wil be able to develop robust scientiifc policy to protect regional ecological security.
