长三角新城区资源利用效率与环境可持续性评估研究

目前全国新城区已经处于严重的失控阶段，如何更加合理的规划全国的新城区布局，思考其可持续发展的方向成为重要研究课题。本研究基于生态经济学理论及新城区空间尺度从资源利用效率与环境可持续性两方面构建可持续性评估指标体系，应用多准则模糊评价方法NAIADE及PROMETHEE排序方法评估新城区资源利用效率与环境可持续性水平，探讨影响新城区可持续性的短板因素。结果表明：①鄞州新城、宝山新城、闵行新城发展的可持续性最优，嘉定新城、苏州工业园区、滨江新城及下沙新城的可持续性偏低；②建设用地开发强度、人口密度、二氧化氮浓度、人均公共绿地面积、5公里半径内三甲医院数量五个指标是目前制约新城区可持续发展的短板因素；③距离主城远近及用地规模对新城区的可持续性有一定的影响。

STUDY ON THE ASSESSMENT OF RESOURCE UTILIZATION EFFICIENCY AND ENVIRONMENTAL SUSTAINABILITY OF NEW TOWNS IN YANGTZE RIVER DELTA

The high-density development and intensive utilization of land will be the great guides for the future urban planning and development in China. At present, the construction of new towns has been out of control, so many researchers engaged in thinking about the direction of sustainable development. This paper selected 10 representative new towns in Yangtze River delta as a research region. Based on the eco-economic theory and spatial scale of new towns, a sustainable development index system has been set up. We used multi-criteria fuzzy evaluation method including NAIADE and PROMETHEE to measure resource utilization efficiency and environmental sustainability of new towns. Meanwhile, the restrictive factors influencing the sustainable development of the new towns were disscussed. The results indicated that:1)The sustainable development level of Yinzhou, Baoshan and Minhang new towns is high, the sustainable development level of Suzhou industrial park, Jiading, Binjiang and Xiasha new towns is low; 2)the five index including land development intensity, population carrying capacity, nitrogen dioxide concentration, per capita public green area, numbers of top three hospitals within a radius of 5 kilometers are the restrictive factors for the sustainable development; 3)the distance from the main city and the scale of land use have some certain influences for the sustainable development of the new towns.
