生态环境敏感的库区山地城市空间发展格局——以三峡库区山地城市云阳县城总体规划为例

Space development pattern of mountainous city in the sensitive eco-environment of Three Gorges Reservoir Region:A case of general planning of Yunyang county

以典型的库区山地城市云阳县城为例,运用景观生态学理论,根据山地生态系统特征,选取自然和社会文化等方面因素的评价因子,划分敏感等级;利用层次分析法,结合GIS空间分析技术,综合判定云阳县城生态环境敏感区类型、特征及其空间分布。立足保护城市内外的河川、分水岭、林地、陡坡、冲沟、滑坡等不适于城市建设的生态环境敏感区,有机整合自然生态环境敏感区与人工生态绿化区,构建了生态敏感区的健康有序、人地关系和谐、可持续发展的山地城镇空间格局。

Three Gorges Reservoir region is classified into different eco-environmental grades via the example of Yunyang county. Natural and social cultural factors are selected ation factors based on the theory of landscape ecology and the characteristics of the mountai system. The eco-environmental sensitive area types, characteristics and spatial distribution sensitive as evalu- nous eco- are com- prehensively evaluated by using the analytic hierarchy process and the GIS spatial analysis techno- logy. To protect the sensitive and unfit-for-construction eco-regions as rivers, watershed, forest lands, steep slopes, ditches and landslides and to integrate organically the eco-environmental sensi- tive area and artificial ecological green area, a reasonable and orderly mountainous town spatial pat- tern of harmonious man-land relationship is constructed for ecoenvironmental sensitive areas.
