长江经济带资源禀赋现状分析——基于地理国情普查

Resources Endowment along Yangtze River Economic Belt——Based on Geographical Conditions Census

提取地理国情普查成果中的水资源、土地资源、交通资源和生态资源成果,采用空间统计方法,测算区域的水资源密度和水源涵养程度,可利用土地资源量和开发干扰状况,以及交通资源集聚度和交通干线影响度,评价了区域生境质量,对比了各要素在长江经济带内部和三大城市群之间的分布差异,为准确把握长江经济带资源现状提供空间参考。

By adopting the outcomes regarding the resources of water,land,traffic,and ecology of geographical conditions census;using spatial statistical method;this paper has calculated the regional water resources density and water conservation degree.At the same time,in accordance with the amount of land resources,development disturbance regime,the cluster degree of traffic resources,and influence value of traffic trunk,it also has appraised regional habitat quantity.In order to accurately master the resource situation in the Yangtze Economic Zone,this paper has not only analyzed the distributive differences of above-mentioned factors within the Yangtze River Economic Belt,but also compared distributive differences between three cities groups in the Pearl River Delta,Yangtze River Delta and the Bohai Sea rim area.
