The Research On Evolution And It’s Driving Force Of Regional Use Water Structure

Water is the fountain of life. Water is an important resource for the production.Andwater is also the basis of ecological balance and stability Sleepy water resources has ledto the problem that various water sector do not enjoy proper configuration of waterReasonably determination and accurate prediction of the use water structure can help toprovide better services to the development and utilization of water resources and to themost stringent regulatory simulation. It is significant for achieving the appropriateallocation of regional water and soil resources and coordinated development of socialeconomy.But the evolution of water consumption structure is a complex process, andthe driving factors is abnormal active.Taking Anhui Province as the study region,thepaper analyses evolution complexity and driving force of use water structure by using avariety of data method models and methods.The main research results as follows:Discussion of development trend of water consumed structure of Anhui Provinceby using information entropy.The results indicated that agricultural water occupied thedominant position, and industrial and domestic water accounted for a small proportionin water consumed structure of Anhui Province; Information entropy of water usestructure is escalating trend and conform to the level of the middle reaches of theYangtze River.According to the features industrial and use water systems,using the synergeticmethods，the coordination degree model of water resources industrial structure isestablished.The finding is that coordinating degree for the system of water-industries ison the low side.We get some comments,for example,narrowing the proportion ofwater in agricultural,promoting water-saving irrigation,developing the third industry.When analyses the driving force,using principal component analysis,we screenedthree principal components.Summarized as population growth, technological progress,economic development.The more important factor,including the proportion of industry,water-saving irrigation area, GDP, consumption level of urban，effective irrigationsurface and per capita green area,and so on.Comprehensive index of driving force is calculated respectively by using thedriving forces index formula. Calculation results are visualized by ArcGIS.The resultsshowed that: Hefei, Bozhou, Suzhou, Chaohu and Huainan et cetera, water structuredriving factors are more complex, use water structure is more favorable trends.
