本文的主要内容有:
1合理预测灌区的国民经济发展,调整灌区作物种植结构。
2 用彭曼公式计算作物需水量,用水量平衡原理重新制定灌区作物灌溉制度,分析灌区水土资源平衡情况。
3 结合原有工程设施,对灌区的灌排沟渠进行重新规划布置,提出主干渠道衬砌的节水措施。
4 计算渠道流量,设计主干渠道的纵横断面,布置典型支渠及其田间工程,校核沟道的排涝能力。
5**灌区续建配套与节水改造项目的工程量计算和投资估算。
6 **灌区续建配套与节水改造项目的国民经济评价和财务评价,判断项目在经济上的合理性。
关键词
灌区;节水改造;作物需水量;灌溉制度;渠道;衬砌;纵横断面;投资估算;经济评价

Infuse the area is a river valley of four lakes of province Hubei a large infuse the area.Infuse area through several decades of movement, irrigate the area increasingly the reduce, the building is aging, infusing the area department to arrange confusion, line up to infuse not to divide.For the sake of the exertive infuse the performance that the area should have, should carry on infusing the area to set up the kit and the stanza water reformations continuously.This text from infuse the problem of the area existence to set out, take the stanza water reformation as the center, pass the theories estimate and compute, carry on design again towards infusing the area, match with various stanza water measure, try hard for will infuse the area construction to become the stanza water high produce of modernization infuse the area.
The textual and main contents have:
1 reasonable estimates infuse the national economy development of the area, adjusting to infuse the area farm crop to plant the structure.
2 Need the amount of water with the formula calculation farm crop, use the equilibrium principle of amount of water to re- draw up to infuse the area farm crop irrigation system, analyze to infuse the equilibrium circumstance of the area Water and soil resources.
3 Combine the original engineering facilities, infuse to line up the ditch to carry on re- programing to arrange towards infusing the area, put forward the stanza water measure of the main stem outlet .
4 Compute the outlet discharge, design the cross section of of the main and dry outlet, arrange the typical model to pay and the engineering of its in the fields, the row ability of the school pit ditch way.
5 infuse the area to set up the engineering quantity calculation and investments that the kit and the stanza waters reform the item to estimate continuously.
6 Infuse the area to set up the national economy evaluation and the finance evaluations that the kit and the stanza waters reform the item continuously, the judgment item is in the rationality on the economy.

** Irrigation District 40 in Hubei Province is a large lake basin irrigation area. Irrigation After several decades of operation, the irrigated area is growing decay, aging buildings, irrigation district canal system layout confusion, regardless of Irrigation and Drainage. ** Irrigation District in order to play due to the effectiveness of the irrigation area should be conducted Rehabilitation and water-saving transformation. This article from the problems of irrigation areas, water-saving transformation as the center, and through theoretical prediction, the re-design of the irrigation area, with various water-saving measures, sought to build water-saving irrigation areas - the modern high-yielding irrigated areas.
The main contents are:
A reasonable forecast of the irrigation area economic development, structural adjustment Irrigation crop cultivation.
2 Penman formula with crop water requirements, water balance principle re-enacted crop irrigation system Irrigation District, the irrigation area of soil and water resources balance.
3 of the original engineering facilities, the irrigated area of irrigation and drainage ditches to re-planning layout, proposed lining the main channel of water-saving measures.
4 channel flow calculation, the design of the main channels for vertical and horizontal sections, layout typical branch canal and its field projects, check the drainage channel capacity.
5 ** Irrigation Rehabilitation and reconstruction of water-saving projects and investment in terms of estimates.
** 6 Rehabilitation and water-saving irrigation area of the project evaluation and financial evaluation of the national economy, the economic judgement of the project is reasonable.
Keywords
Irrigation District; water-saving reform; crop water requirements; irrigation system; channel lining; vertical and horizontal cross-section; investment estimates, economic evaluation

The ** irrigation area is a Hubei Province four lake basin large-scale irrigation area. The irrigation area passes through several dozens years movement, the irrigated area weakens day by day, the building gets older, the irrigation area ditch is the arrangement is chaotic, the irrigation and drainage does not divide. In order to display the benefit which the ** irrigation area should have, should carry on the irrigation area to subsequent construction necessary and the saving water transformation. This article embarks from the irrigation area existence question, take saves water the transformation as the center, through the theory forecast and the computation, carries on the re-engineering to the irrigation area, coordinates each kind of saving water measure, makes every effort to construct the ** irrigation area the saving water high production the modernized irrigation area.
This article primary coverage includes:
1 reasonable forecast irrigation area national economy development, adjustment irrigation area crops planter structure.
2 uses the Penman formula computation crops water demand, the water consumption principle of detailed balance to formulate the irrigation area crops irrigation system, the analysis irrigation area water and soil resources balanced situation.
3 union original project facility, fills a row of drainage ditch to the irrigation area to carry on plans the arrangement, proposes the branch canal lining saving water measure.
4 computation channel current capacity, the design branch channel vertically and horizontally the cross section, the arrangement typical branch canal and the field project, the examination trench drains waterlogged land ability.
5 ** irrigation areas subsequent construction necessary and the saving water transformation project resilience computation and the investment estimate.
6 ** irrigation areas subsequent construction necessary and the saving water transformation project national economy appraisal and the financial appraisal, the judgment project in the economical rationality.
Key word:
irrigation area; Saving water transformation; Crops water demand; Irrigation system; Channel; Lining work; Vertically and horizontally cross section; Investment estimate; Economic evaluation
