摘要:

三生空间的合理布局与有序开发对城市实体空间布局、土地功能组合、国土空间秩序开发、引导人口资源环境与社会经济可持续发展具有重要意义。本文从土地资源的三生功能视角出发,以宁波市为例,提出了基于三生空间的城市国土空间开发建设适宜性评价框架;运用GIS技术,采用国土空间综合分区“千层饼”方法,以30m×30m栅格为基本单元,定量评估了宁波市国土空间开发建设适宜性;从分类到综合,多尺度揭示了宁波市国土开发的建设适宜规模与开发潜力。研究表明:①2012年宁波市生态空间面积为5872.33km2,占宁波市总面积的60.35%,主要分布在宁波南部宁象片区;生产空间面积为2442.34km2,占宁波市总面积的25.10%,集中分布在宁波市中部与北部平原;生活空间面积为1415.78km2,占宁波市总面积的14.55%,多集聚在宁波市核心六区;②宁波市不适宜城市建设空间居多,达5655.34km2,生态、生产与生活空间占比约为34∶9∶1;临界适宜城市建设空间居中,为2279.84km2,以生态空间与生产空间为主,二者占比约为2∶1;比较适宜空间为1526.71km2,以生产与生活空间为主,二者占比约为1∶2;一般适宜空间居后列,为268.56km2,生态空间、生产空间与生活空间比约为2∶1∶13;③宁波市北部余慈与南部宁象板块开发潜力较大,未来可有序拓展开发空间;中心城区国土空间开发建设适宜性较好,但开发历史悠久,开发潜力有限,未来开发宜以盘活存量,提高效率为主要途径。

Abstract:

The reasonable and orderly development of ecological-living-industrial spaces is of great significance for land function combination,ordering spatial development,guiding population resource environments and ensuring socio-economic sustainable development in urban areas. In this study,a set of frameworks for the suitability evaluation of spatial development suitability for city construction was built,from the perspective of the ecological-living-industrial function of land resources. The spatial suitability method was applied to evaluate spatial suitability for city construction in Ningbo city,using GIS technology with comprehensive territory spatial partition of ‘puff pastry’ means. The results show that in 2012,the ecological space of Ningbo covered 5872 km2,which accounted for 60.35% of the total area,and the distribution was mainly in Ningxiang in southern Ningbo. Industrial space covered an area of 2442km2,accounting for 25.10% of the total area,and the distribution was concentrated in central and northern plains in Ningbo. Living space covered an area of 1415.78km2,accounting for 14.55% of the total area and concentrated in six core areas of Ningbo. There was more unsuitable region for city construction space than other types in Ningbo in 2012;the unsuitable area was 5655km2 and the rate of ecological,industrial and living spaces was 3491. The critical suitable space area was 2279km2,and the ecological and industrial space rate was 21. More suitable space was 1526km2,and the industrial and living space ratio was 1:2. Generally suitable space was last at 268km2. The development potential is larger in Yuci in the north and Ningxiang in the south. Even though the territory spatial development suitability for construction was better in the center,it has a long history of development and the development potential was limited. It would be appropriate to revitalize this stock and improve its efficiency.
