摘要
集成水资源管理将水资源管理阶段分为供给管理、技术性节水、结构性节水和社会化管理四个阶段。本文基于地区投入产出模型,运用结构分解分析(SDA)方法,将水资源消耗影响因素量化分解为技术性、结构性(中间需求效应)和系统性(最终需求效应)三个因素,对张掖市2002-2012年间水资源管理阶段进行评价。结果显示:在2002-2007年间,促使张掖市水资源消耗减少的最主要动力来自于结构性(中间需求)因素,判断张掖市的水资源管理处于结构性节水阶段;经过虚拟水战略调整,2007-2012年间,系统性因素(最终需求效应)对张掖市用水减少作用凸显,此阶段张掖市的水资源管理处于由结构性节水到社会化管理的过渡阶段。结构分解分析(SDA)方法为水资源管理阶段的评价提供了一种简明途径。
Under integrated water resources management,water resources management is decomposed into 4 phases： supply management,technical water conservation,structural water-saving and social management. Based on regional input-output model,using structural decomposition analysis(SDA） method,the consumption of water quantify factors is decomposed into technical factors,structural factors(intermediate demand effect） and systemic factors(final demand effect）,to evaluate Zhangye City in the 2002-2012 water management stage. The results show that： during the period 2002 to 2007,the main force that drives the reduction of water consumption in Zhangye City comes from the structural(intermediate demand） factors that determine water management in structural phase; during the period 2007 to 2012,systemic factors(final demand effect） play a significant role in water reduction,and the water resources management of Zhangye City at this stage transferred from the structural stage to socialized management stage by virtual water strategy adjustment. Structural decomposition analysis(SDA） method provides a simple way for evaluating water resources management stage.
