Abstract:
In order to clarify the water poverty status of Sichuan province, in this study we established an evaluation index system of water poverty in Sichuan Province, calculated the water poverty index of the 21 cities from 2006 to 2013 by using balanced weighting and water poverty index model, and analyzed the temporal and spatial pattern of the province and each city based on the geog raphic information system ( GIS) . The results showed that from 2008 to 2011, the comprehensive and balanced water poverty improvement situation in Sichuan province was hindered by the Wenchuan earthquake on May 12th, 2008. As the government actively advanced water conservancy reconstruction and targeted poverty relief through water conservancy, the water poverty situation improved from 2006 to 2013. The enhancement of water management capacity and the improvement of water environment played a key role in advancing water security . Furthermore, the 21 cities varied greatly in their capacity to handle water poverty and the gapwasg radually widening . Chengdu City and Ya'an City were infinitesimal water poverty areas; Panzhihua City, Guangyuan City, Aba Prefecture, Ganzi Prefecture, and Liangshan Prefecture were slight water poverty areas; Luzhou City, Mianyang City, Leshan City, Meishan City , and Yibin City were moderate water poverty areas; Zigong City , Deyang City, Nanchong City , Bazhong City, and Ziyang City were strong water poverty areas; Suining City, Neijiang City, Guang'an City , and Dazhou City were extreme water poverty areas. The government should make more efforts to enhance water poverty awareness, increase the efficiency of water use, optimize the allocation of water resources, improve the scientific guarantee rate, manage water resources strictly, adjust industrial structure and production mode, systematically control the water safety risk, improve its water management ability , increase fiscal investment, actively promote the reform of water right system, streng then poverty relief through water conservancy, and boost poverty alleviation.
