【摘要】 资源环境是人类赖以生存与发展的空间系统,资源环境承载力水平间接影响人类活动的范围和广度。基于协调发展理念的甘南藏族自治州资源环境承载力研究从土地资源、水资源和生态资源三个角度出发,以村庄为基本研究单元利用限制性分级的方式对甘南藏族自治州资源环境承载状态做出等级划分,并对其空间特征做出分析,为区域资源环境的监测、保护与开发提供技术支持,解决资源环境问题导致的社会经济问题,促使地区社会经济与资源环境有序发展,为国土空间规划开展以及"双评价"成果补充提供现实依据。研究表明:(1)土地资源承载力超载村庄数量接近甘南州总村庄数量的一半,该区域内的村庄经济社会、气候资源环境相对适宜,人口急剧程度较高。在进行空间优化时要划定超载等级,合理制定农牧业发展政策。(2)水资源承载力超载村庄数量接近甘南州总村庄数量的70%,甘南州中部地区资源环境承载状态有待改善。(3)生态条件优越,70%以上的村庄生态承载力处于盈余状态,生态基底良好,重点关注生态敏感区生态安全的保护与优化。(4)综合来看,甘南州一半的村庄资源环境承载状态处于超载状态,但其土地面积不到甘南州全域面积的1/3,资源环境整体状态良好,部分人口稠密区域有待提升。更多还原

【Abstract】 Resources and environment are the spatial system for human survival and development.The level of carrying capacity of resources and environment indirectly affects the scope and breadth of human activities.Research on the carrying capacity of resources and environment in Gannan Tibetan Autonomous Prefecture based on the concept of coordinated development from the perspective of land resources,water resources and ecological resources,the village is used as the basic research unit to classify the carrying status of resources and environment in Gannan Tibetan Autonomous Prefecture by means of restrictive classification,and its spatial characteristics are analyzed.It provides technical support for the monitoring,protection and development of regional resources and environment,solves the social and economic problems caused by resources and environment,promotes the orderly development of regional social economy and resources and environment,and provides practical basis for the development of land and space planning and the supplement of ’double evaluation ’ results.The research shows that:(1) The number of villages with overloaded land resource carrying capacity is close to half of the total number of villages in Gannan Prefecture.The villages in this area have relatively suitable economic,social and climatic resources and environment,and a high degree of population explosion.In the process of spatial optimization,the overload level should be defined and the agricultural and animal husbandry development policy should be reasonably formulated.(2) The number of villages with water resources carrying capacity overload is close to 70 % of the total number of villages in Gannan Prefecture,and the carrying status of resources and environment in the central region of Gannan Prefecture needs to be improved.More than 70 % of the villages are in a surplus state of ecological carrying capacity,and the ecological base is good,focusing on the protection and optimization of ecological security in ecologically sensitive areas.(4) On the whole,half of the villages in Gannan Prefecture are in an overloaded state of resource and environment carrying capacity,but their land area is less than 1/3 of the total area of Gannan Prefecture.更多还原
