摘要:在评价土地利用效益经典指标数据不全的特殊情况下,构建了评价指标体系,以长春南部都市开发区为例,将研究区与东三省其他典型城市新区进行对比,利用现有数据,进行了城市新区土地利用效益的综合性研究。结果表明,城市新区的土地利用效益评价方法应与成熟的城市土地利用效益研究方法有所不同;长春市南部都市开发区的经济效益及综合效益偏低,但社会效益和生态效益尚可。

Abstract: In the special case of having incomplete classical-indicators,the evaluation index system was constructed. Taking new urban development zones in Southern Changchun as an example,the comparison was made between the study area and other typical new urban development zones in Northeast China. Then,combined with existing data,the comprehensive study on land use efficiency of the new urban development zone,which is still in the initial stage,was carried out. The results showed that the study on land use efficiency of the new urban development zones should be different from the mature study on land use efficiency of the cities. And the social and ecological benefits of the study area are acceptable,while the economic and comprehensive benefits are poor.

Key words: new urban development zones; land use efficiency; fuzzy comprehensive evaluation; the new urban development zone in southern Changchun

城市新區是指在地域空间上与主城区邻接或接近,具有各种城市要素功能的城市多核心的重要组成部分,表现为城市组团或城市副中心[1]。城市新区一般处于母城的郊区化地带,受母城辐射带动作用较强,经济发展虽然滞后于母城,但却是城市化速度最快、最活跃的区域,是城市外延式扩展的载体[2]。发展新区既是城市空间拓展的内在要求,也是优化城市结构、完善城市综合功能的有效模式之一[3-6],许多城市力图通过建设城市新区来解决经济快速发展和城市化带来的一系列问题,但并不是每个实行新区发展的城市都取得了令人满意的效果[7,8]。在中国人地关系日益矛盾突出的背景下,在18亿亩耕地红线不动摇前提下,处理好快速增长的土地需求与有限的土地资源之间的关系是亟须解决的关键问题。……
