A Plan For Urban Water Right Trade Mechanism Based On Eco-environment Protection Objectives In Northwest Arid Area

Surviving and developing of human beings is an eternal theme. As a pivotal ecology controlling factors of northwest arid area in china, whether water resources achieve sustainable utilization as soon as possible may directly influences the evaluative course of eco-environment in region and the living prospect. With high level intelligence and responsibility for the society, human beings need to find out a useful way to achieve the sustainable utilization of water recourses through bettering the behavior of themselves and changing the thinking and developing mode. The key point for sustainable water resources utilization lies in the efficiency of capital allocation, which mainly deceived by the property rights institution. Importing the conception of water rights and its transactions brings into full play of fundamental role for the allocation of water resources market, activates the water usage more efficiency and improvement by the price leverage of water resource, which may increase more water consumption to restore and improve the eco-environment of west arid zone without significant affect of regional economy development.Through analysis the situation of the northwest arid zone which is short of water resources, with single model of economy development and household income, low awareness of public environmental, traditional water usage is difficult to change, the paper draw a base conclusion that the evolution of current eco-environmental region may be unsustainable. Based on the theory of water rights and its transactions, researching the example for domestic and abroad, we set up the institutions of water rights transactions aiming to protect the environment of arid zone in northwest. Through orderly and controllable development of mechanism which may steeply formed water transactions internal or inter-industry, to use resource value judgment differ from each water user, to stimulate entrepreneur input capital on water saving irrigation and approach the public to form the water saving custom an approach to the models of water usage and the transformation policies about water-saving cities, raise efficiency of region water resources sustainable utilization and economic development at last. At the same time, make the best use of government functions in environmental protection and activeness of the public to raise more water demand for ecosystem, in the last which could restore and improve the arid zone, make the usage of water resources and eco-environment sustainability.Considering the representativeness of urban and acquisition of data, the paper chose Jinchang as the research object of the deal system in water rights transactions. The paper analysis the deal system in water rights transactions, through which and the local water sector construction case of water saving, the writer draw a conclusion that the machine mode may accord with economical development of society and the evolution of eco-environment. After the model being operated, the water consumption of eco-construction in region is guaranteed which make eco-environmental restore and improve feasible.The water right trade mechanism of this paper is only one of researching viewpoints in china, but is a profitable probe which need more study and discuss to solve the water resource and eco-environment problems in arid zone of china.
