如何分析区域资源环境与社会经济之间的协调匹配程度,是促进区域经济可持续发展首先需要厘清的问题。基于资源环境承载协调理论,构建了基于双曲距离协调度的资源-经济系统的协调分析模型方法。根据该模型对全国依赖地下水资源且开发程度较高的514个县的地下水资源和经济数据进行了协调关系分析,评价了各县地下水资源禀赋与其承载的经济体之间的协调关系水平,结果显示2个系统之间的协调匹配程度及空间上具有较大差异性。东北和西北大部分地区处于地下水资源与经济协调的正向区间,区域经济发展仍具有一定潜力,华北及南方大部分地区处于负向协调区间,经济的发展超越了地下水资源的承载能力。 相似文献

沧州市经济持续发展水资源支撑能力研究 总被引：1，自引：0，他引：1
在对沧州市水资源现状分析的基础上,从水资源及其利用、区域发展和生态环境等三个方面选取了7类指标建立评价指标体系,并对沧州市所辖的15个县（市）的水资源支撑能力进行了分析评价。根据评价结果,得出以下结论：①沧州市的水资源和人口分布、经济发展、耕地资源以及生态环境需水等不相协调,水资源匮乏已成为沧州市经济持续发展的瓶颈;②沧州市所辖的15个县（市）中,有任丘、河间等12个县（市）水资源和区域发展极不匹配,水资源支撑能力明显不足。因此,沧州在未来的经济发展中应实施＂量水发展＂战略,对水资源进行科学管理和优化配置,确保沧州经济的可持续发展。 相似文献

针对榆林地区水资源相对贫乏,煤炭资源不合理的开采对地下水资源造成巨大破坏,严重威胁着该地区的可持续发展的问题,应用系统工程方法,将水资源放在社会、经济、资源、生态、环境所组成的复合系统中进行整体研究,构建地下地下水资源-生态环境-社会经济系统模型,可以为水资源的优化配置、开发利用规划、管理决策、落实最严格的水资源管理制度提供技术支撑。分析结果表明榆林地区在水资源、环境和经济目前处于不协调阶段,经济发展较快,但水资源相对贫乏,经济的发展对环境造成很大有破环并且对于环境的治理和保护投入的资金较少,采矿区水资源污染较为严重。 相似文献

Coastal area is the region with the highest degree of economic and social development and the largest ecological stress in current China, where the proportions and the spatial patterns of developed coastal resource and environment are determined by projects planning. Ecological carrying capacity evaluation is the necessary prerequisite for sustainable utilization of natural resources and protecting ecological environment to ensure healthy and sustainable economic and social development to project planning. Based on the pressure types of projects planning on resources and environment, the concept and contents of coastal ecological carrying capacity were redefined for enhancing the practical value of ecological carrying capacity evaluation. The domestic and foreign research progress and advances related with coastal ecological carrying capacity evaluation were reviewed, which included habitat suitability evaluation, suitability assessment of construction land development, reclamation suitability evaluation and assessment of sea water environmental capacity. The conclusion noted that domestic research of coastal ecological carrying capacity needs to build a complete system of ecological carrying capacity evaluation methodology based on extensive reference to foreign research results, and quantitative evaluation and spatial visualization research related with coastal ecological carrying capacity should be carried out to provide strong support for ecological civilization process of economy and society in coustal areas. 相似文献

Research on the carrying capacity and security of water resources is vital for its contribution to implementing sustainable development goals. The limitation of water resources is one of the most important factors that influence the sustainable utilization of resources. Studying the carrying capacity of water resources will not only facilitate monitoring and forecast of national resources and environmental carrying capacity, but also be valuable for building ecological civilization. According to the principles of evaluation system, the carrying capacity of water resources on Shandong peninsula is explored. A comprehensive evaluation model of the carrying capacity of water resources is constructed based on the carrying capacity of water resources index and the composite of water resources index. The results show that the capacity of water resources on Shandong peninsula is generally consistent with overexploitation, and that the development and utilization of water resources has reached a considerable scale under existing economic and technological conditions. The carrying capacity of water resources in this region is relatively small, and the contradiction between supply and demand of water resources is alarming. Relative countermeasures are put forward, to improve the water resources carrying capacity and to provide a basis for future sustainable development and utilization of water resources in this region. 相似文献

采用主成分分析法并结合SPSS,对1999-2013年重庆市土地持续利用与生态环境的耦合关系进行分析,研究结果表明:1999-2013年土地持续利用指数逐年递增,土地开发利用强度逐年不断加大,城镇化大规模的建设是土地利用强度升高的主要原因;生态环境质量除了在2000-2004年生态环境指数呈“V”字型发展之外,总体呈上升态势发展;重庆市土地持续利用与生态环境耦合发展度由0.387 4（轻度失调衰退土地利用损益型）上升至0.754 0（中级协调发展经济主导型）,但2011年情况有所变化,土地持续利用指数首次低于生态环境指数,耦合发展基本类型由生态主导型转向经济主导型发展,经济发展方式由土地利用制约型演变为生态环境制约型,生态环境效益滞后于土地资源经济效益。土地资源总体利用水平提高和生态环境改善的双重作用是耦合关系由失调发展转化为协调发展的主要原因。现阶段应坚持土地资源集约利用与保护并举,优化经济结构与技术创新齐下,发展循环经济和清洁能源,维系相对稳定的生态环境运行机制,确保重庆市土地资源可持续利用。 相似文献

陕北能源化工基地煤炭、石油、天然气、岩盐等矿产资源储量丰富,经过近20a的开发,已初步建成为中国重要的能源接续地和大型煤化工基地。但该区又具有水资源相对短缺、生态环境脆弱的特点,加之近年来煤炭生产和转化等资源开发增长速度较快,采煤造成的区域性环境污染与生态破坏问题较为突出,严重制约着该区的可持续发展。通过探索建立陕北能源化工基地生态补偿机制,解决了煤炭资源开发与生态环境保护的矛盾,使资源得到适度、可持续的开发利用,环境生态得到持续的恢复和改善,从而使该区的经济发展与保护生态环境相协调,最大限度的实现了可持续发展的战略。 相似文献

传统水资源评价方法分别从质、量两方面分别对水资源进行评价,割裂了水资源的内在联系,已不能满足经济发展对水资源评价提出的新要求。为此,必须从水资源与社会经济、环境协调发展角度出发,根据可持续发展原则,提出一套集评价指标体系、定量分析、分级标准的水资源评价方法。以陕西水资源评价为基础的实例研究,为陕西水资源与社会经济、环境的和谐发展提供了新模式。 相似文献

The Beijing-Tianjin-Hebei (BTH) region is an important engine for China’s socioeconomic development. Timely and effectively assessing constraint factors of resources and environment is of great significance for the sustainability assessment and the sustainable development of this region. However, comprehensive assessment research considering key resource and environmental constraints are still lacking. In this study, therefore, the limiting factors of resources and the environment in the BTH region were assessed based on the framework of landscape sustainability science. First, we chose five limiting factors, including topographic condition, geological environment, water resource, land resource, and atmospheric environment, to assess the constraints of resources and the environment using the single-factor evaluation method and the multi-factor comprehensive evaluation method. Based on the results, we divided the whole region into five subregions, i.e., the ecological conservation subregion, the geological disaster subregion, the water resource scarcity subregion, the atmospheric pollution subregion, and the cropland protection subregion. The results revealed that the northern BTH region was highly constrained by topographic conditions, the central BTH region was strongly constrained by geological environment and water resources, whereas the southern BTH region was constrained mainly by land resources and atmospheric environment. In addition, water resource was the main limiting factor for regional population growth and economic development. In 2010, the water resource scarcity subregion had a total population of 39.59 million, an urban population of 76.90%, and a gross domestic product of 2 455.57 billion yuan. We argue that the sustainable development of the BTH region should explicitly consider the resource and environmental limiting factors, implement land use optimization according to local conditions, maintain multiple land use types and diverse management strategies, based on the perspective of “strong sustainability”, so as to promote the regional sustainable development. 相似文献
