摘要
结合供给侧和需求侧的关系构建水资源空间均衡评价模型,建立了包含供给子系统和需求子系统共12个评价指标的水资源空间均衡评价体系,基于五元联系数定量评估和分析水资源空间均衡水平的状态和变化过程,并采用减法集对势法对水资源空间均衡水平变化的发展趋势和影响因素进行诊断分析。将该模型应用于乌兰察布市11个旗县区,结果表明:水资源空间均衡水平从2011—2020年得到改善的有6个旗县,变化不明显的有5个旗县,其中集宁区一直处于低水平均衡状态;2011—2020年乌兰察布市水资源空间均衡整体水平呈现逐年改善的趋势,2020年供给子系统水平中,集宁区处于反势状态,化德县、商都县处于偏反势状态,需求子系统水平只有集宁区处于偏反势状态;乌兰察布市的脆弱性指标为人均水资源量和生态环境需水负荷。
This paper constructed a spatial equilibrium evaluation model of water resources combined with the relationship between supply side and demand side.Based on the quantitative evaluation and analysis of the state and change process of water resources spatial equilibrium level by the five-element connection number,the evaluation model of water resources spatial equilibrium is constructed,and the evaluation system of water resources spatial equilibrium including 12 evaluation indicators of the supply subsystem and the demand subsystem is established.Then,the development trend and influencing factors leading to the change of water resources spatial equilibrium level are diagnosed and analyzed by the subtraction set pairs.Applying the model to 11 counties and districts in Ulanqab City,the study shows that the spatial balance level of water resources has been improved from 2011 to 2020 in 6 counties and 5 counties,among which Jining District has been in a low level of equilibrium.From 2011 to 2020,the overall level of spatial balance of water resources in Ulanqab City has shown a trend of improvement year by year.In the level of supply subsystem in 2020,Jining District is in a counter trend state,while Huade County and Shangdu County are in a counter trend state.At the demand subsystem level,only Jining District is in a negative state.The vulnerability indicators of Ulanqab City are water resources per capita and water demand load of ecological environment.
