不同发展模式下资源环境承载力评价——以海南省为例     

牛方曲  杨欣雨  孙东琪 《热带地理》2020,40(6):1109-1116

文章关注于产业、人口与资源环境要素的作用关系，建构了资源环境承载力综合评价框架，并以海南省为案例区开展应用研究。该框架首先对区域产业重要性进行评价并分级，为产业结构调整提供依据；其次解析了区域产业、人口资源消耗与污染排放强度，最后，基于产业评价结果设定不同的产业结构调整情景，结合产业和人口的资源消耗与污染排放强度评价不同产业结构下的资源环境承载力，即产业和人口的规模上限。结果表明：2016年海南省的经济规模并未超载，产业有进一步发展空间。其中土地资源成为海南省发展的首要限制因素，其次是水环境；海南经济效益较高的支柱产业和基础性产业多为高耗水、高污染的产业，亟需加强水资源的集约利用，并降低污染排放强度。为提升经济发展规模上限，需要培育低能耗、低排放的产业。文章建构的资源环境承载力评价方法将产业、人口与资源环境相联系，其评价结果政策意义更为明确，可为优化产业结构调整、控制产业及人口发展规模提供决策参考。  相似文献   

辽宁省城市化进程与资源环境压力时空耦合过程研究     

杨欣雨  牛方曲 《世界地理研究》2022,31(2):317-328

“新型城镇化”战略要求人与自然和谐共生,走绿色低碳、高效集约的可持续发展道路。构建城市化与资源环境压力的评价指标体系,并应用灰色关联度和耦合协调度模型,对辽宁省城市化进程与资源环境压力的时空耦合过程进行研究。结果表明：1996—2017年辽宁省城市化水平不断提高,资源环境压力呈下降趋势;两者的耦合作用一直处于颉颃阶段,耦合协调关系经历了低度协调向中度协调再向高度协调转变的过程;建成区面积是最典型的城市化限制因素,土地资源占用是最典型的资源环境限制因素。辽宁省14地市城市化水平的空间差异较大,沈阳、大连始终居于省内城市化发展前列,而朝阳和铁岭较为落后;城市化与资源环境压力的耦合协调度在空间上呈现出东南高、西北低的特点,这与城市化发展水平呈现一定的空间对应关系。  相似文献   

资源环境承载力综合评价方法在西藏产业结构调整中的应用     

牛方曲  杨欣雨  张晓平 《地理学报(英文版)》2020,30(2):319-332

With the degradation of natural resources and environment caused by industrial development in some developing countries,the requirement of implementing a“social ecological”approach to development is imminent.Resource and environment carrying capacity provides a means of assessing regional development potential by measuring regional sustainable development in terms of economy,population and resources&environment.This study develops a conceptual framework for resource and environment carrying capacity estimation to support the co-development planning of industries,population and resources&environment.First,the framework constructs an index system for evaluating importance of industry or influence based on the role of industry played in the local socio-economic system.Then,the framework computes the quantitative relations through the importance of local industry,population size and resource utilization and environment effects,and subsequently estimates the resource and environment carrying capacity of the study area.With a particular attention to its land resources,water resources and environment,the Tibet case study shows that:the non-ferrous metal mining,tourism,liquor and refined tea industries play a pillar role in the Tibet’s socio-economic system;under each industrial structure,land resource carrying capacity is the weakest,and water resources carrying capacity is the strongest;to focus on tourism will improve local resource and environment carrying capacity.The research results provide a solid guide for Tibet government’s co-actions in industrial restructuring,ecological protection,and the pursuit of economic development.This study will contribute to bridge the gap between theoretical research and practical applications of resource and environment carrying capacity,and help local governments plan the regional“socio-ecological”sustainable development.  相似文献
