城市生态用地的“协调—集约”度创新研究

The innovative research of the "harmonious-intensive"extent for urban eco-land

城市化进程的快速推进加剧了城市土地的紧缺和生态环境的恶化,走土地集约利用的发展道路势在必行。为此,以天津市为实证对象,建立了一套考察生态用地“协调—集约”程度的定量评价指标体系,并改进得到“协调—集约”度三维模型,同时结合2004年天津市土地规划修编专题之七的课题实地调研数据,首次对市辖各区县的“协调—集约”度进行了创新研究,最终指出全市大部分地区的生态用地均不同程度存在生境恶化和布局欠佳问题,“协调—集约”程度总体偏低。

The scarce urban land resource and the pollution of ecological environment have been aggravated by the rapid propulsion of urbanization, therefore, the way of intensive land use is imperative under the situation. Thus, take Tianjin as the positive subject, the quantitative evaluation system of harmonious - intersive extent of eco - land has been founded, and the three - dimension model has been also gained. After that, by the application of the data of the revision series 7 of land planning ＂the evaluation system of land intensive utilization and the management research of planning and apply in Tianjin＂, the innovative research of ＂harmonious- intensive＂ extent of each district and county has been devel- oped, and the results has been analyzed： the problems in eco- land, which the environment is deteriorated and the layout is poorly designed, are existing in various degrees in the mass of Tianjin city. The whole ＂harmonious- intensive＇extent is low in Tianjin.
