华北自主管理井灌区节水制度的实证研究——以河北省衡水市桃城区为例

Study about self-management water saving system in north China——Taking Hengshui city Taocheng district of Hebei province as example

对节水型社会建设试点衡水市桃城区"一提一补"节水制度进行了阐释,对试点村和非试点村农田灌溉制度节水效果进行抽样调查,数据分析表明试点村对比非试点村农田灌溉平均用水量减少显著,边际用水量不断趋近农作物相应的理论需水量;节水制度改变了农民的节水意识和用水行为,使村民间产生竞争节水。"一提一补"节水制度作为内生要素,通过用水者协会做为制度变迁的有效载体,将价格机制中的"高水价"和政策性补贴相结合,对水资源可持续利用进行杠杆调节,减少了水资源浪费。

The paper interpreted the water-saving system of ＂increase the price and subsidy＂ in Taocheng District of Hengshui City which was construction pilot of water-saving society,conducting a sample survey about the water-saving effect in irrigation system of pilot villages and non-pilot villages.There was a significant reduce in average irrigation water use in pilot villages compared with non-pilot villages by data,and marginal water use constantly approached to the corresponding theoretical crop water demand;the water-saving system also changed the the awareness and water saving behaviors of famers,which created competition to save water among the villagers.As a endogenous factor,＂increase the price and subsidy＂system taken Water Users Association as a an effective vehicle for institutional transformation,combined with the high price of water in price mechanism with the policy of subsidies,taken a level regulate in sustainable use of water resources,reduced the waste of water resources.
