摘要/Abstract

摘要： 城市增长边界通过充分考虑地区生态约束条件,可以有效控制城市无序蔓延,是统筹区域生态保护与城市开发建设的重要规划理念.如何通过生态本底条件确定城市建设开发的优先位置、规避建设开发生态风险一直是城市增长边界划定的核心内容.本研究以济宁市太白湖新区为例,引入有序加权平均算法完成生态适宜性评价结果的情景识别,并借助地表温度反演、雨洪淹没模型等算法进行生态风险空间识别.适宜性评价结果表明: 适宜建设区占太白湖新区全境面积的25.3%,不宜建设区占20.4%,其余区域为限制建设区.规避风险控制区域后,弹性城市增长边界在近期共占地2975 hm²,在远期占地6754 hm²,而最终刚性城市增长边界共占地9405 hm².作为一种新的方法,生态适宜性情景算法和风险情景模拟的应用可以为城市增长边界识别提供更有效的定量支撑.

Abstract: Urban growth boundary, with full consideration of regional ecological constraints, can effectively control the unordered urban sprawl. Thus, urban growth boundary is a significant planning concept integrating regional ecological protection and urban construction. Finding the preferential position for urban construction, as well as controlling the ecological risk, has always been the core content of urban growth boundary delimitation. This study selected Taibai Lake New District in Jining City as a case area, and analyzed the scenario of ecological suitability by ordered weighted ave-raging algorithm. Surface temperature retrieval and rain flooding simulation were used to identify the spatial ecological risk. In the result of ecological suitability, the suitable construction zone accounted for 25.3% of the total area, the unsuitable construction zone accounted for 20.4%, and the other area was in the limit construction zone. Excluding the ecological risk control region, the flexible urban growth boundary covered 2975 hm² in near term, and covered 6754 hm² in long term. The final inflexible urban growth boundary covered 9405 hm². As a new method, the scenario algorithms of ordered weighted averaging and ecological risk modeling could provide effective support in urban growth boundary identification.
