Spatial matching analysis of water resources in the intake area of South-North Water Transfer Project based on Gini coefficient

Inter-basin water transfer projects have important practical significance in exploitation and
utilization of water resources and optimizing water resources all ocation. To provide some reference for interbas in water transfer,
the spatial matching degree between water resources and population,GDP, landuse and
 precipitation before and after water transfer was explored using Lorenz curve,Gini coefficient and unbalanced
 index, for the middle line and east line intake area of South-North Water Transfer Project.Gini coefficient and
 unbalanced index were found to have decline dafter water transfer, indicating that water transfer project had
 promotional effect to ease unmatched situation in spatial matching of water resources, and to coord inate
 development degree between  water resources and other influencing factors. The present  work  will have
 practical significan cein analyzing spatial  matching of  water resources in intake area of inter-basin  water
 transfer.
