摘要
城镇建设适宜性评价是资源环境承载能力和国土开发适宜性评价的重要内容,也是国土空间规划和管理工作的基础。以东南沿海火山岩区具有代表性的福建省宁德市为例,基于“双评价”指南构建了城镇建设适宜性评价体系,对城镇建设的适宜性及潜力进行评价分析,进而对城市未来发展方向及格局提出建议。宁德市城镇建设适宜区面积2682.88 km^(2),占全区陆地面积的19.98%;城镇建设不适宜区面积5979.06 km^(2),占全区陆地面积的44.53%。火山岩区受典型地貌影响,城镇建设适宜区连片性较差,分布相对零散,花岗岩区城镇建设适宜区连片度较好。适宜区展布特征及连片度整体受不同岩性区地形地貌控制,各县(区、市)差异较明显,潜力区内生态功能用地类型偏多,农村宅基地、茶园及果园地等具备城市扩展建设供给潜力。建议加强“沿东发展,向西推进”的发展方向,形成“一核-三轴-多组团”的城市发展格局,达成山海协调发展局势。
The suitability of urban construction is an important element in evaluating resources and environment carrying capacity and suitability of national land utilization,and also a basis for national spatial planning and management.Based on the“Double Evaluation”guidelines,an evaluation system for the suitability and potential of urban construction was set up for Ningde City,one of the coastal volcanic areas in southeast China,and relevant suggestions on future development direction and pattern of the city were put forward.The results show that the suitable zone for urban construction in Ningde covers an area of 2682.88 km^(2),accounting for 19.98%of the total regional land;while the unsuitable zone covers an area of 5979.06 km^(2),accounting for 44.53%.Due to the typical geomorphology of the volcanic area,the suitable areas for urban construction in the region is poor in contiguity with relatively scattered distribution,while the contiguity of the suitable zone for granite area urban construction is better.The distribution characteristics and contiguity of the suitable areas are generally controlled by the topographies and geomorphological patterns of different lithology,with obvious differences among counties(districts and cities).There are more ecological function types land in the potential area including rural residential land,tea plantations and orchards,all of which constitute the potential for urban expansion and construction.It is suggested to strengthen“developing along the east and advancing westward”as a future development direction,and that the urban development pattern of“one core-three axes-multiple clusters”should be formed to achieve a coordinated development situation among the mountains and the sea.
