【摘要】For reasonable allocation and utilization of water resources of shaanxi province,the water resources based on the analysis of the present situation,based on the principal component analysis based on multivariate linear regression model and the forecast method of shaanxi province in the next five years the demand for water resources is forecasted.The results show that the next five years at an average annual rate of growth in shaanxi province water resources condition,to supply capacity of shaanxi province put forward severe test.Combined with the future development plan of shaanxi province to natural ecological environment,this paper analyzes the contradiction between supply and demand of water resources,and puts forward the countermeasures of sustainable utilization of resources in shaanxi province.%为合理分配和利用陕西省水资源,在对其水资源现状分析的基础上,基于主成分分析的基础上利用多元线性回归模型预测方法,对陕西省未来5年水资源的需求量进行了预测.结果表明:未来5年陕西省水资源年均处于增长状态,对陕西省供水能力提出了严峻考验.结合未来陕西省发展规划以自然生态环境,分析了水资源的供需矛盾,提出陕西省资源可持续利用的对策. 【总页数】8页(37-44)
