【摘要】：正确评价区域水资源承载能力,对合理、充分利用水资源以及促进区域社会、经济的可持续发展具有重要的现实意义。论文采用升半Г型分布曲线模拟水资源承载力各指标对评价过程的影响,并通过区域水资源承载力评价指标体系规范化处理,对升半Г型分布函数进行改进,提出用于水资源承载力评价的升半Г型分布指数公式。经过规范化数据处理方式,升半Г型分布指数公式就可以忽略指标个数的影响,具有普适性。公式中的参数采用粒子群算法优化后,得到适用于多区域、多项指标的具有通用性和普适性的水资源承载力评价公式。将优化好的指数公式应用到玛纳斯河流域和塔里木河流域水资源承载力评价等实例分析,研究结果表明:指数公式的评价结果与其他多种方法的评价结果一致,消除了评价指标数目多少的限制和区域性评价指标各异性的限制,省去了复杂的编程计算工作,具有实用性和可行性。在实际评价中,待评价区域的水资源承载力评价指标体系即使与论文选定的评价指标体系不同,也能经过规范化处理后直接采用该指数公式进行评价,为评价模型的普适化、简单化提供了一条途径。
[Abstract]:To evaluate correctly the carrying capacity of regional water resources, to make rational use of water resources and to promote regional society, The sustainable development of economy is of great practical significance. The paper simulates the influence of each index of water resources carrying capacity on the evaluation process by using the ascending half distribution curve and normalizes the evaluation index system of regional water resources carrying capacity. This paper improves the distribution function of the rise-half type distribution, and puts forward the formula of the ascending half-type distribution index for the assessment of water resources carrying capacity. Through the standardized data processing, the influence of the number of indexes on the index formula can be ignored. The parameters in the formula are optimized by particle swarm optimization, which are suitable for multi-region. The universal and universal evaluation formula of water resources carrying capacity of many indexes is presented. The optimized index formula is applied to the evaluation of water resources carrying capacity in Manas River Basin and Tarim River Basin, and some other examples are analyzed, such as the evaluation of water resources carrying capacity in Manas River Basin and Tarim River Basin. The results show that the evaluation results of the exponential formula are consistent with those of other methods, and the limitation of the number of evaluation indexes and the differences of regional evaluation indexes are eliminated, and the complicated programming calculation work is eliminated. It has practicability and feasibility. In the actual evaluation, the index system of water resources carrying capacity evaluation in the area to be evaluated can be evaluated directly by the index formula, even though it is different from the evaluation index system selected in this paper. It provides a way for the generalization and simplification of the evaluation model.
