By using fuzzy comprehensive evaluation method, the assessment on water resources carrying capacity in Gonghe Basin was conducted: Water resource carrying capacity of Gonghe County is less, while that of Guinan County and Chaka Town of Wulan County are greater; water resources of Gonghe Basin could sustain cultivated land of 652.6 thousand acres and grassland of 2 368.6 thousand acres respectively in 2020, water resources of Gonghe Basin could sustain cultivated land of 948.2 thousand acres and grassland of 2 247.6 thousand acres respectively in 2030.展开更多

[Method] By using the cosine vector included angle method, the index weight was determined. The projection value of water resources carrying capacity in Guizhou Province was counted by using the multi-objective gray relational projection method. Moreover, the projection value which was counted by the index weight determined by the mean-variance method was as the control. [Result] The projection values which were obtained by two kinds of methods were very close, and the ordering result was consistent. [Conclusion] In the assessment of water resources carrying capacity, it was feasible to use the cosine vector included angle method to determine the index weight.展开更多

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 The results show that although there are various methods of WRCC,the major methods used have become out-of-date and stagnant,and new more sophisticated methods and technologies are lacking.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.展开更多
水资源承载力是指一个区域或国家所能提供的可持续利用的水资源量,它直接关系到社会经济的可持续发展和生态环境的健康,也是衡量特定区域水资源供需平衡能力的重要指标。本文将对云南省水资源承载力进行分析评价,首先运用博弈论组合赋权...水资源承载力是指一个区域或国家所能提供的可持续利用的水资源量,它直接关系到社会经济的可持续发展和生态环境的健康,也是衡量特定区域水资源供需平衡能力的重要指标。本文将对云南省水资源承载力进行分析评价,首先运用博弈论组合赋权法,结合专家打分的层次分析法和客观分析原始数据的熵权法及变异系数法,得出综合权重;然后采用灰色关联度改进的逼近理想解的排序方法(Technique for order preference by similarity to ideal solution,TOPSIS)及耦合协调分析法,综合得出云南省在2008~2020年间水资源承载力的变化情况并做出评价。结果表明,2008~2020年水资源承载力总体呈上升趋势,其中,经济子系统和社会子系统的承载力始终保持持续上升的状态,而水资源子系统和生态环境子系统则出现波动情况。2008~2014年,云南省为大力发展经济,牺牲了一定的水资源合理开发利用,但在2014年后,开始注重水资源保护,实施绿色可持续发展战略,水资源子系统的承载力逐步提升。展开更多
