Pishihang Irrigation Practice and Water Resources Optimal Thinking

Active introduction of market mechanisms. Irrigation Management Office and the county (district) Collection implementation of water supply and water interaction,[link widoczny dla zalogowanych], water supply before each stage, the allocation of water rights to enter into supply contracts, clearly the rights and obligations of both supply and demand, promoting the efficient allocation of water resources. By optimizing the scheduling, can solve the irrigation of agricultural water, water for urban water and environmental problems are intertwined, and promote efficient use of water resources. 4. Strengthen the management and innovative services combined to achieve the realization of interaction of supply and demand in the service apartment management to serve the purpose of promoting management, Administration invested nearly 30 million RMB, CHINAWATERRESOURCES Irrigation Water Management established a network of public services scheduling, adhere to the irrigation water supply Information Release system, strengthen information to guide, to avoid information asymmetry caused by the loss of irrigation water supply, water supply information to promote transparency; developed irrigation water supply system of consultation, co-ordination of resources, climate, ecological, environmental, economic and management factors, implementation of scientific irrigation scheduling decisions; the formation of irrigation research system,[link widoczny dla zalogowanych], establishment of irrigation Steering Group, in-depth field moisture control irrigation, water in the first-hand information, and enhance the timeliness of irrigation scheduling. Innovative services to measures to promote the healthy development of water collection, supply and demand sides to achieve a positive interaction. Successful practice, has made a huge water-saving efficiency benefits. According to statistics, total irrigation water in 2004 1.997 billion m, than in normal years, water saving nearly 10 billion m; rice output reached 500 million t, compared with a normal year yield 60 million t, yield 13%, the highest on record. Clearly the initial water rights, the implementation of water supply contracts, clearly the responsibilities and obligations of both supply and demand, strengthen the legal status of both supply and demand. According to analysis, the next 10 years, industrial and agricultural irrigation and ecological water demand will increase by 600 million m or more, in addition to relying on increased investment to improve water efficiency measures such as canal water, the implementation of the optimal scheduling, the implementation of water-saving irrigation, water supply and demand to achieve balance of important measures. Third, promote Pishihang Irrigation Resources Optimal Thinking 1. Optimal allocation of irrigation water to build a system to support the current, Pishihang Irrigation counties (districts) of the key engineering and control engineering has not yet achieved full unified management. Water engineering and irrigation works sub-unit management, resulting in the institutionalization of irrigation water scheduling arrangements for the lack of a unified system of support elements, it is difficult to achieve efficient allocation of water rights and smooth operation. Must quickly straighten out the irrigation system and water resources management project management system, the formation of the government's macroeconomic regulation and control, watershed integrated management, irrigation management committee of democratic consultation, quasi-market operation, water users in the irrigation management system. 2. Optimal allocation of water resources to build irrigation works based on the present,[link widoczny dla zalogowanych], old and damaged irrigation projects more than 50%, only 0.45 coefficient of canal water use, engineering factors led to a lot of water wasted. Must accelerate the transformation of water-saving irrigation area, construction and optimal water resources engineering system adapted. In accordance with the Irrigation District project planning,[link widoczny dla zalogowanych], through the transformation of water, irrigation district's irrigation guarantee rate to 80% canal water efficiency increased to 0.6. At the same time, but also to explore the industrial use of agricultural water rights paid to the mechanisms for the transfer, thus speeding up the pace of water saving reform for irrigation area. 3. Build irrigation system to protect water resources optimal allocation of irrigation scheduling inter-basin and inter-regional, cross-industry, must as soon as possible \Irrigation management unit and the power of water users at all levels obligations to ensure the seriousness and scientific irrigation scheduling. 4. Optimal allocation of resources to build irrigation water price adjustment mechanism based economic means to establish optimal allocation of water resources, above all, a reasonable water price formation mechanism. Currently, the water price is far from compensating the cost of agricultural water requirements, water price structure is measured as a single price, resulting in natural, public welfare losses without compensation, excess fare,[link widoczny dla zalogowanych], seasonal, peak-type water far from being established, the lack of effective water resources optimization scheduling means of economic regulation. Irrigation water should fully take into account the spatial and temporal changes in the value of water resources under the variation of the factors fully into account the price of water in regulating the water demand, economic structure and distribution of productive forces and to reduce the burden on peasants economic and political factors. Also given to the price of water rights, and promote the priority areas of water resources, high-efficiency configuration. 5. To build optimal allocation of irrigation water irrigation and technology support to face the complex scheduling environment, the economy should be established to cover irrigation, technology, resources, ecology, climate standard parameters of the mathematical model; build irrigation soil moisture, water and the main crop growing season Water Monitoring The forecasting system, the formation of configuration, save and protect the Trinity scheduling system, promote the intensification of irrigation water scheduling.
