水资源效益与城乡供水一体化发展耦合效应分析——以洛川县为例
Analysis of coupling effect between water resources benefits and the integration of urban and rural water supply development: a case study of Luochuan County
In order to study the coordination degree between water resources benefits and the integration of urban and rural water supply, based on the evaluation index system on the coupling between water resources benefits system and the integration of urban and rural water supply development system, Luochuan county in Yan'an city was used as an example to apply impulse response function(IRF), coupling degree and coupling coordination degree to conduct analysis of coupling effect between water resources benefits system and the integration of urban and rural water supply development system. The results showed that the increase of water-saving irrigation area and the increase of the level of the integration of urban and rural water supply have mutual promoting effects. Agricultural ten thousand yuan GDP water consumption first continues to decrease and then increases with the increase of the development level of the integration of urban and rural water supply, but the response of the development level of the integration of urban and rural water supply to the increase of agricultural ten thousand yuan GDP water consumption is just opposite. The comprehensive evaluation index of water resources benefits shows a trend of increase as a whole and the comprehensive evaluation index of the integration of urban and rural water supply development increases year by year in Luochuan county from 2007 to 2015 and the correlation between them is as high as 0.965. The coupling degrees between water resources benefits system and the integration of urban and rural water supply development system are all between 0.4 and 0.5 in Luochuan county and the coupling coordination degree between them increases year by year, whichdevelops from disorder stage (2007-2010) to coordination stage (2011-2015).
