中原城市群核心城市资源环境承载力研究

通过对城市群型地区的分析, 提出资源环境承载力研究要充分考虑资源流动性。选用中原城市群9座核心城市为研究对象, 参考压力状态响应模型构建评价指标体系, 并利用层次分析法进行评价。利用外来资源依赖指数对研究区的资源依赖度进行分析。结果表明: 1) 通过对比郑州市2004-2014年考虑与不考虑资源流动性的评价结果, 表明只有在考虑资源流动性时, 评价结果才能真实地反映区域发展状态; 2) 中原城市群核心城市水和能源资源比较紧张, 但通过外来资源的供应, 可基本上满足区域的发展需求, 然而各核心城市的环境情况均不容乐观; 3) 研究区资源环境承载能力由高到低的顺序为漯河、许昌、新乡、郑州、济源、焦作、洛阳、平顶山、开封; 4) 根据外来资源依赖指数可知, 9座核心城市的粮食资源均可自给自足, 开封、新乡等地的能源资源需外部供应, 郑州、开封等地的水资源需外部供应, 综合来看, 水资源比能源资源的依赖程度大。

Research of Carrying Capacity on Resource and Environment in Core Cities of Central Henan Urban Agglomeration

By analyzing the characteristic of urban agglomeration areas, proposing that considering the mobility of resource is essential in researching carrying capacity, the research used core cities of Central Henan urban agglomeration as cases to study, referencing press-state-response model to build the target system of carrying capacity, considering resource supply and consumption & environmental pollution and treatment, using AHP method to evaluate. Reliant exponential is used to evaluate the dependence severity. The result shows that according to the comparison of two results considering resource fluidity or not in Zhengzhou in 2004-2014, only considering resource fluidity can reflect the real condition of an area. Core cities of Central Henan urban agglo-meration are short of water and energy resources but are enough to use with the supply of external resources. The orders of the carrying capacity index on resource and environment are Luohe, Xuchang, Xinxiang, Zhengzhou, Jiyuan, Jiaozuo, Luoyang, Pingdingshan and Kaifeng. According to the reliant exponential of external resources, grain resources in these nine cities are self-sufficiency. External energy resources are needed in Kaifeng, Xinxiang, etc. External water resources are needed in Zhengzhou, Kaifeng, etc. More external water resources are needed than external water resources.
