【摘要】：中国正处在快速城市化、新型工业化与农业现代化互动发展时期,文章着眼于这一背景,从区域人口、资源、环境与经济、社会协调发展的视角,提出了基于人口、土地、经济规模的资源承载力阈值、资源负荷、资源强度概念及其表征方法;结合分岔理论和突变理论,引入突变级数法进行资源承载力的多目标综合评价,以2011-2013年辽宁省水资源系统综合评价为例进行实证分析,结果表明:2011年辽宁省14个行政单元中,人口、土地、经济规模超过水资源承载力阈值的城市分别为8个、8个、4个,水资源强度高于全省平均值的城市分别为6个、6个、10个;与2011年相比,2013年辽西北的朝阳、阜新及铁岭等3个城市的水资源应急响应级别提高,辽东南的大连、丹东、盘锦及营口等4地水资源系统负荷减轻,辽宁省水资源危急态势趋缓。通过对比分析,认为评价结果基本符合近年来辽宁省水资源开发与利用的整体状况,评价过程相对简便、评价结果更加直观,因此便于推广应用,为不同时空尺度内的资源优化配置及区域可持续发展的定量研究提供了新的思路和评价方法。
[Abstract]:Chinese is in Rapid City, industrialization and modernization of agriculture development period, this paper focuses on the background, from the regional population, resources, environment and economic and social development perspective, based on the size of the economy, population, land resources carrying capacity, resource load and resource intensity threshold concept and characterization method; combining with bifurcation theory and catastrophe theory, the introduction of catastrophe progression method for comprehensive evaluation of multi objective resource carrying capacity of water resources in Liaoning Province, using the 2011-2013 comprehensive evaluation index system and empirical analysis, the results showed that 14 administrative units in 2011 in Liaoning Province, population, land, economies of scale more than the carrying capacity of water resources of the city are threshold as of 8, 8, 4, higher than the provincial average intensity of water resources of the city were 6, 6, 10; compared with 2011, 2013 in Northwest Liaoning The emergency response level of water resources in 3 cities such as Yang, Fuxin and Tieling increased. The load of water resources system of 4 places in Southeast Liaoning Province, such as Dalian, Dandong, Panjin and Yingkou, was reduced, and the critical situation of water resources in Liaoning province was slowing down. Through the comparative analysis, that the evaluation result is basically consistent in recent years the development and utilization of water resources in Liaoning province's overall situation, the evaluation process is relatively simple, the evaluation results are more intuitive, it is convenient for popularization and application, for different spatial and temporal scales of the resources optimization allocation and quantitative Study on regional sustainable development provides a new idea and a new evaluation method.

【正文快照】： 1引言随着全球人口与经济规模持续增长,世界各国面临的资源短缺问题日益凸显,因此如何促进资源的集约利用、可持续利用成为全球尤其是广大发展中国家普遍面临的难点问题之一。资源承载力是衡量一个国家或地区的资源数量、质量对其人口基本生存与发展的支撑能力的重要标度之一,
