Water Poverty Measure Evaluation of Tongchuan City
From the resources,capabilities,facilities,use,environment five dimensions to establish water poverty index system,selection of27 evaluation index,evaluation index standardization of original data to the secondary processing,using the analytic hierarchy process( AHP)to calculate the weight,WPI model is adopted to measure the Tongchuan City water poverty levels of 2008- 2011. Results show that the Tongchuan City during 2008- 2011 water poor scores overall decline,fell to 0. 16 from 0. 79,showing a trend towards good direction,2009 rise in volatility in terms of ability and the environment. Facilities and use of the situation is still severe,the score on the histogram of the  short board factors and got intuitive reflect the interannual variability. The research results can provide water poor evaluation index system construction to provide the foundation,so as to provide theoretical basis for scientific management of water resources in Loess Plateau.
