Irrigation development in the Sanjiang Plain Wetlands Protection Project and the need for


Decrease in biodiversity, ecological function to reduce the emergence of the trend of ecological deterioration, destruction of wetland resources will seriously threaten the local economic development and living environment of residents, protection of wetlands and their biodiversity has become essential. Implementation of a comprehensive wetland protection, and thus protection of Heilongjiang Province, to embark on a coordinated development and utilization of sustainable development. 2.3 after joining WTO is the economic development needs of rice in Heilongjiang Province after China's accession to the WTO agricultural products one of the few strong varieties. Currently, rice production in green-based farming, has become the Sanjiang Plain, the region's major economic growth point, workers with unprecedented enthusiasm. Over the years, the workers have accumulated rich experience in production and irrigation technologies. Thus,[link widoczny dla zalogowanych], transit through the development and utilization of water, construction,[link widoczny dla zalogowanych], irrigation, improve grain quality and yield of rice in the near future pollution-free outside. 2.4 The development of the Sanjiang Plain, the need for comprehensive management of contiguous land in the Sanjiang Plain, flat, fertile soil, climate,[link widoczny dla zalogowanych], rain and heat light in the same quarter, rivers and lakes rich in natural resources, water quality, greater cross-border water, a unique water development and utilization conditions, geographical and ecological environment is better and suitable for the development of green rice and crop production, is the focus of our province and the national agricultural development zone. Sanjiang Plain area is large, equivalent to China's Jiangsu Province. Existing cultivated land area lower grain yield, yield potential, reserve water-rich land resources and cross-border region to more than a small, high mechanization, high rate of food commodities, is a national commodity grain base. The governance of the Sanjiang Plain in 1982 have been included in national plans, the development of irrigation and protection of wetlands construction is planning to determine the content and the need for integrated development and management, will enter the water conservancy construction in the region a new phase, the majority of workers to improve the standard of living to adapt to the future 2.5 Regional efficiency, the need for workers to get rich development of the Sanjiang Plain Irrigation Project will have a huge economic benefits for regional development, staff has brought tangible benefits to get rich. The first section, surface water irrigation and the irrigation area running costs per hectare were 495 and 750 ~ 600 ~ 810 yuan, compared with surface water irrigation per hectare irrigation lower annual operating costs 210 255 dollars. The second mention quality, surface water irrigation irrigation water temperature higher than 1O ~ 12. C, can increase the activity accumulated nearly 300 ��, a level of high quality rice per hectare income of 825 ~ 1155 yuan. The third efficiency, surface water irrigation well irrigation rice processed than whole rice milled rice rate increased by 5 per ton sold more than 5O yuan, 375 yuan per hectare overcharged. By more than three rice prices in 2006, surface water irrigation per hectare irrigation more than 1755 ~ 2040 yuan revenue. 2.6 Construction of a stable commodity grain base, to achieve the national security system of food production needs of north Fifth Plenary Session of the Fifteenth Party Conference on Agricultural Development proposed a and establishing a socialist market economy, China's national conditions and requirements of food security system to ensure a basic balance between grain supply and demand, According to the data, by 2030 China's population will reach 1.6 billion, the demand for food than the current increase of about 400 million t. 400 million t of food to solve the incremental problem, the Northwest region of China to no water, no water in southwest China, only the Northeast region, especially in the Sanjiang Plain area of water to the basic balance of resources, maintaining national food security in the 21st century is obligatory in Heilongjiang Province responsibility. Ensure that no increase in the case of land reclamation area, to increase the food supply, and only through expansion of irrigation to increase food yields to do it. This building and the stability of commodity grain base in Heilongjiang Province,[link widoczny dla zalogowanych], to achieve the national security system of food production north of great significance. Sanjiang Plain Wetlands like a huge reservoir, Sanjiang Plain is a day set to build a natural treasure track, not a copy, once the damage is not copied, so we have to do a good job to focus on wetland water environment. Improving water system to ensure that wetland water, recovery and reconstruction wetlands,[link widoczny dla zalogowanych], cherish protect and develop the good in the Sanjiang Plain of soil and water resources, to develop along the surface water irrigation, to improve the Sanjiang Plain water environment, to ensure national food security, participation in international competition , are very necessary and very urgent.
