| Use amount of water increment, water resources supply strain along with the rapid development of our country economy, lead the in the field construction of Huang Guan Qu to still keep being placed in a beginning stage. Adopt a ground irrigation, water waste of resources is serious. The important step dint solves the problem of the weakest small scaled farmland irrigation"infuse to line up the last kilometer" at present. Such as the construction of the embankment pond, the pump water conservancy facilitieses, such as station and machine well... etc., daily maintenance and management, make it at retain water, lead water, lift links, such as water and catchment... etc. to always be placed in good movement status.(The beard Yi is new)the development of village rely on the production of food and rely on comprehensive production ability. But this again with farmland irrigation constuct of development relevant. The full condition that income increase of farmers and agriculture boost production is the construction of the farmland irrigation facilities, the exaltation of farmer living standard and life quality also needs water conservancy facilities, can also improve the ecoenvironment of village.(Zhang Xiu Juan’s farmland irrigation constucts existent problem and counterplan research)aim at this situation, strengthen in the field construction, raise a making use of of water resources efficiency, increase the comprehensive irrigation efficiency of in the field construction. This text constituted part to carry on thorough analysis to the importance that the in the field constucts, output each expenses went deep into a research from the economic angle the rightness the in the field construction the movement, and main contents and research achievement of this thesis are as follows:(1)Analyzed each part of in the field construction to constitute, aim at the actual circumstance that the yellow river downstream leads construction in the yellow in the field analytical get influence in the field construction of the factor mainly have a perfect the kit of water conservancy facilities, district ecoenvironment, water resources environment and farm crop to plant structure, and headwaters sediment content... etc.. These factors have key function to the scale influence that the in the field constucts and influence in the field construction to synthesize exertion of efficiency.(2)Analyzed to pass to carry out item, the item area farmland infrastructure got perfect, produce a condition improvement, the farm crop resists dry, Hong Lao the ability to build up of the etc. natural disaster, the output efficiency includes irrigation to boost production efficiency, ditch to retain water efficiency and economy energy to save work efficiency. Through calculation, the item economic internal rate of return is13.61%, the economic clean current value is10,277,400dollars, economic efficiency expenses than1.35is bigger than1, express that the item has better economic efficiency.(Wu Hong Li)(3)Analyzed engineering will raise the management level of item area further after being finished, help the plan to use water with the water, economy. Promote item area pipe line reason system reform, carry out water resources reasonable to prepare, strengthen district anti-drought, anti-disaster ability, improvement ecoenvironment, maintenance district economy of can keep on a development.(4)The construction that passes engineering, the kit of water conservancy facilities is perfect and the construction of the farmland stanza water engineering, can economize a water resources, effective of rise an anti-drought to defend Lao and improve the effect of water environment. Strengthened an infrastructure at the same time construction, improved a production, ecosystem condition. Combine pass to adjust an agriculture to plant structure, practice scale to turn, intensive turn management to raise a land to produce efficiency, lower production cost, raise farmer life quality, help the agriculture industry to turn development and increment farmer income, promote village economy the development walk the road of virtuous cycle. |
