摘要
农业水价的高低直接影响农民种粮的积极性,从而影响到国家的粮食安全。针对农业水权分配下农业水价计算模型进行研究,建立了长期水权下农业水价计算模型和短期水权下农业水价模型,结合农民经济承载力,提出了基于水权分配的不同水文年动态协调水价模型,并在山东桓台项目区进行应用。结果表明,随着农户实际取水量的变化,丰水年农业水价变化范围为0.268元/m3到0.54元/m3,平水年农业水价变化范围为0.163元/m3到0.606元/m3,枯水年农业水价变化范围为0.113元/m3到0.938元/m3,考虑不同水文年的动态协调水价模型更能够反映农民不同水文年用水的实际情况,更有利于提高农民节约用水的积极性和农业水价的落实,对推动区域农业水价改革具有重要指导意义。
The level of agricultural water prices directly affects the enthusiasm of farmers to grow grain,thus affecting the country's food security.The agricultural water price calculation model for agricultural water rights allocation was studied in this paper,and the agricultural water price calculation model under long-term water rights and the agricultural water price model under short-term water rights were established.Based on the economic carrying capacity of farmers,a dynamic coordinated water price model based on different hydrological years under water rights allocation was proposed and applied in Shandong-Huantai project area.The results showed that with the change of actual water intake of farmers,the agricultural water price in wet years varied from 0.268 to 0.54 yuan/m3,the agricultural water price in normal years varied from 0.163 to 0.606 yuan/m3,and the agricultural water price in dry years varied from 0.113 to 0.938 yuan/m3.This study results indicate that the dynamic coordinated water price model considering the change of water volume in different hydrological years can better reflect the actual situation of farmers'water use in different hydrological years,and is more conducive to improving farmers'enthusiasm for water conservation and implementation of agricultural water price,and has important guiding significance for promoting regional agricultural water price reform.
