| Currently, there are serious shortages and inefficient phenomenon in our agricultural waterresources, promoting farmers adopt water-saving technologies is an important measure to solvethis matter.On the other hand, adjusting water demanding by water price is a significantguaranty of achieving water-saving technologies spatial spreading and keeping agriculturedevelopment sustainable.This paper evaluating the relative efficiency of the engineering of canal seepage control,low-pressure pipe water supply, micro-irrigation, spray irrigation, flow irrigation, straw mulchtechnology and plastic covering technology based on the summary of economic benefits ofvarious water-saving technologies, with the Data Envelopment Analysis (DEA) used inefficiency evaluation, using C2R model to construct the efficiency of water-saving irrigationtechnology evaluation model, then giving the reason of inefficience.Currently, there are manyserious problems of our agricultural water price system, however, water price has a strongimpact of farmer's adoption of water-saving technologies,and water price is an importantmeasure to promote technologies. Therefore, reasonable development of water price system hasa great significance for water-saving agriculture. Taking the JingHui irrigation district as aexample, under the condition that trying to promote various water-saving technologies systemto calculate the irrigation water price used economic models, and compared with the existingprice. The results show that current water price far below the water price which purpose forpromote various water-saving technologies system.Besides,the study found that the lack ofincentives is the bottleneck in the application of water-saving irrigation technologypromotion,achieving award to farmers' water-saving behavior by adjusting water price hasgreat significance to enhance water using efficiency and solve the shortage of waterresources.Therefore,we do the research of compensation of water price in JingHui irrigationdistrict,preliminary formulate the water price compensation standard of various water-savingtechnologies,in order to stimulate farmers to raise awareness of water conservation and improvethe initiative of farmers,in order to raise the level of agricultural technology popularizationand application. |
