基于物元模型分析的龙凤山灌区水资源承载力综合评价

Comprehensive evaluation for water resources carrying capacity of Longfengshan Irrigation District based on matter-element model analysis

依据物元分析理论,建立了龙凤山灌区水资源承载力的评价模型,即物元模型。通过对龙凤山灌区水资源承载力进行综合评价,得出龙凤山灌区2009年,2015年和2025年水资源承载力均属于Ⅱ级,灌区水资源开发利用已有相当规模,但仍有一定的开发潜力,可以采用相关工程措施进一步开发水资源的结论。

In this paper, combined with the evaluation for water resources carrying capacity of Longfengs- ban Irrigation District, the specific application of the matter element analysis theoretical methods were dis- cussed, and the evaluation model of water resources carrying capacity of Longfengshan Irrigation District were established, that is, matter-element model. Through the comprehensive evaluation, a conclusion is drawn that water resources carrying capacity of Longfengshan Irrigation District in 2009, 2015 and 2025 ranks level 2, and there has been already a considerable scale in exploitation and utilization of the water re- sources in the irrigation district, and that there is still certain development potential on the exploitation and utilization of the water resources by using related engineering measures.
