| 摘 要： | 运用遥感/GIS技术,选择土地利用类型、高程、坡度、植被覆盖、所在流域与丹江口水库距离等5个因子,采用因子加权叠加法,对十堰市规划区生态敏感性进行分析. 按敏感度的高低将规划区划分为高敏感区、中敏感区、低敏感区和不敏感区4级,并提出分区保护与发展的建议,为规划区城乡建设和生态环境保护提供重要支撑和依据.

| Abstract: | With GIS technology and a factor-weighted superposition method, eco-sensitivity in the Shiyan planning area is analyzed based on five selected factors, including land use pattern, elevation, gradient, NDVI, and distance between the river basin and the Danjiangkou reservoir. In the evaluation, the whole area is divided into 4 zones. Advice for each of the zones is provided for environmental protection and urban-rural construction. |
