摘 要:以四川省水资源为研究对象,利用SPSS23.0和MATLAB作为基础计算工具,利用因子分析将原始变量提取成少数几个主要变量,然后采用熵权法对提取后的新变量进行赋权,最终计算水资源承载力。并绘制出四川省承载力程度可视图。从纵向上看降水总量、水资源总量及供水量是对承载力影响最大的三项指标。由于经济技术的不断发展行业用水效率逐渐提高,自2015年后四川省用水量趋于稳定。但从横向分析中发现四川省水资源空间分布不均匀,西部高原区水资源承载力得分较高而东部盆地承载力得分较低,其中成都水资源承载力最差。Taking Sichuan province as the research object,SPSS23.0 and MATLAB as the basic calculation tools,the original variables were extracted into a few major variables by factor analysis,and the new variables after extraction were weighted by entropy weight method,and the water resource carrying capacity was finally calculated.And draw out Sichuan province bearing capacity degree can view.From the lengthwaysperspective,the total amount of precipitation,total amount of water resources and water supply are the three indexes that have the greatest impact on the carrying capacity.With the continuous development of economy and technology,water consumption in Sichuan province has been stable since 2015 due to the gradual improvement of water efficiency in industries.However,it is found from the horizontal analysis that the spatial distribution of water resources in Sichuan province is not uniform.The western plateau region has a higher water carrying capacity score and the eastern basin has a lower bearing capacity score,among which Chengdu has the worst bearing capacity.
