徐州城市地质调查在城市“三线”划定中的应用

The application of urban geological survey in ″three limits″ delineation of Xuzhou

随着人口和经济活动的进一步聚集,生产、生活、生态空间的矛盾日益突出,"三线"(即永久基本农田保护红线、生态保护红线、城市开发边界线)的划定在我国经济结构实现转型发展关键期,对优化城乡空间结构、确保国家粮食安全、严守生态底线等至关重要。以徐州城市地质调查成果为基础,基于地质条件对城市发展的制约和影响,提出城市"三线"的调整建议,不仅可为构筑生产空间集约、生活空间宜居、生态空间优美的城市空间格局提供地质依据,亦可为城市地质调查工作提供工作转型和战略调整方向。

With the further concentration of population and economic activities in China,the contradiction between production,life and ecological space is becoming increasingly prominent. The delineation of ″three limits″（ i. e. permanent preservation of arable land minimum,ecological red line,urban growth boundary） plays an essential role in the critical transformation of our economic structure,optimizing urban and rural spatial structures,ensuring national food security,and safeguarding the ecological red line. Based on the results of Xuzhou Urban Geological Survey and the restriction and influence of geological conditions on urban development,this paper puts forward the suggestion of adjusting the urban ″three limits″,which can provide geological basis for constructing the urban spatial pattern with intensive production space,livable living space and beautiful ecological space. Moreover,it can direct the transformation and the strategic adjustment for urban geological survey.
