【摘要】：为了探索安徽省用水驱动因素,运用LMDI因素分解模型,对安徽省2011-2014年用水变化驱动效应进行了测算,并采用空间自相关分析方法,借助GeoDA095i与ArcGIS空间分析软件,对用水驱动效应空间关联格局进行了分析。结果表明:1)经济增长对安徽省用水变化具有显著正向增量效应,而用水强度则呈现为负向减量作用;2)经济增长效应、结构变动效应、用水强度效应呈现为不显著聚集特征;3)合肥市、安庆市为经济增长效应的显著高值聚集中心和结构变动效应的显著低值聚集中心,马鞍山市、淮南市为经济增长效应的显著低值异质中心以及结构变动效应、用水强度效应的显著高值异质中心,六安市为用水强度效应的显著低值聚集中心。研究结果可为安徽省制定差别化的水资源可持续政策提供科学依据。
[Abstract]:In order to explore the driving factors of water use in Anhui Province, the driving effect of water use change in Anhui Province from 2011 to 2014 was measured by using the LMDI factor decomposition model, and the spatial autocorrelation analysis method was used. With the help of GeoDA095i and ArcGIS space analysis software. The spatial correlation pattern of water-driven effect is analyzed. The results show that the economic growth has a significant positive increment effect on water use change in Anhui Province, while the intensity of water use is negative. 2) Economic growth effect, structure change effect and water use intensity effect are not obvious. 3) Hefei City, Anqing City is the significant high value aggregation center of economic growth effect and the significant low value aggregation center of structure change effect, Ma'anshan City. Huainan city is the significant low value heterogeneity center of economic growth effect and the significant high value heterogeneity center of water use intensity effect. Luan City is the significant low value aggregation center of water intensity effect. The results can provide scientific basis for making differential sustainable water resources policy in Anhui Province.
