资源环境承载力定量评价与综合计量是资源环境承载力研究由分类走向综合的关键技术环节。本文从系统角度出发,提出了"人居环境适宜性分区——资源承载力限制性分类——社会经济发展适应性分等——资源环境承载力警示性分级"的资源环境承载力综合评价的研究思路与技术路线,构建了具有平衡态意义的资源环境承载力综合评价的三维四面体模型,对区域资源环境承载力监测预警机制的建立具有清晰的政策指导意义。基于上述模型方法,以公里格网为基础,以分县为基本单元,开展了西藏自治区的资源环境承载力综合评价。研究表明,西藏3/4左右土地、4/5以上人口所在的县域资源环境综合承载力处于盈余或平衡状态,资源环境综合承载状态良好;人居环境以不适宜和临界适宜为主要特征,社会经济发展水平普遍滞后,人居环境自然适宜性和社会经济发展水平在较大程度上限制了西藏资源环境承载力的发挥及其提升。

Study of the Population Carrying Capacity of Water and Land in Hainan Province

Journal of Resources and Ecology 2019年第4期10卷 353-361页

作者： HAO Qing FENG Zhiming yang yanzhao YOU Zhen CHENG Ping DENG Ling Institute of Geographic Sciences and Natural Resources Research Chinese Academy of Sciences Beijing 100101 China Chinese Academy of Natural Resource Economics Beijing 101149 China Key Laboratory of Carrying Capacity Assessment for Resource and Environment MNR Beijing 101149 China College of Resources and Environment University of Chinese Academy of Sciences Beijing 100190 China

In recent years, the rapid growth of population in Haikou and Sanya has caused extensive concern about the carrying capacity of Hainan Province. To formulate scientific population and environmental policies, it is necessary to research the relationship between population, carrying capacity and economic growth. In this paper, three indicators, grain production, nutrient composition of agricultural products and water resources, are used to measure carrying capacity quantitatively;the employment elasticity coefficient method is used to set the employment elasticity coefficient and the growth rate of regional GDP to estimate the total population needed to support economic growth;PADIS-INT population forecasting software that has parameters to track total fertility rate and net migration rate is used to predict demographic changes. The results show that, as of 2050, the total population of Hainan Province will not have exceeded the upper limit of the carrying capacity of land and water resources. In general, there is no overpopulation problem in the province, but there may be structural problems related to population, such as a large proportion of elderly people, labor shortages, and a high social dependency ratio. It is suggested that the local government should adopt positive population policies, improve the management of natural resources and the environment, and guide the balanced development of population in the province.

Research Methods of Water Resources Carrying Capacity: Progress and Prospects

Journal of Resources and Ecology 2018年第5期9卷 455-460页

The study of water resources carrying capacity（WRCC）,a major component of resources and environment carrying capacity（RECC）,began relatively recently. However,WRCC has witnessed a rapid development in terms of concept,calculation methods,and empirical research in recent years. WRCC has become an important criterion for rational development and utilization of regional water resources. This paper first briefly reviews the development process of WRCC. It then evaluates and contrasts the representative research methods of conventional trend（CT）,system dynamics（SD）,multi-objective model analysis（MOMA）,comprehensive evaluation（CE）,and dynamic simulation recursive（DSR）. The results show that although there are various methods of WRCC,the major methods used have become out-of-date and stagnant,and new more sophisticated methods and technologies are lacking. Specifically,our analysis found that the index system,scientific robustness and comprehensiveness of evaluation criteria of current research methods are insufficient and need to be improved. In addition,the dynamic research of WRCC should receive more attention,and it requires further study to make it more applicable to real-world uses. Finally,a set of monitoring and early warning systems should be established and applied in demonstration areas to meet the urgent needs of water resource management in the new era.
