而用适当比例的海水直接灌溉可以大大缓解干旱地区土壤水分蒸发，提高土壤保水能力，一些比较耐盐的经济植物直接用海水灌溉也可以获得比较满意的经济产量，且对一些经济植物品质产生有益的影响，可以取得显著的经济效益[3] 。

On tne basis of reviewing the metnod of calculating firm energy of draw-down period and considering the conflicts between the hydropower and irrigation water requirement, this paper proposes a modificative method, applying multipurpose decision of system engineering combined with incremental dynamic programing with analysis to obtain an optimum program which would yield the maximum economic benefit.

本文针对水库设计供水期保证电量计算方法存在的问题，和发电与灌溉用水等矛盾，应用系统工程多目标决策，和增量动态规划与分析相结合的方法，提出了能使电力系统基建投资省、保证电量大、和灌溉用水多的综合利用效益高的优化方案；同时还得出了具有长期予报的水库供水期最优调度的一般规律，应用该规律能迅速方便地得出最优方案。

For instance, we repeatedly warn the farmers not to irrigate, yet they secretly go to the vineyard and irrigate at night because they think the soil is too dry.

例如，即便我们再三警告他们不要灌溉葡萄园，这些农户仍然会在夜间偷偷灌溉。从传统农业的"经验"来看，葡萄园的土壤太干了；同时，我们的庄园又在不断的向农户强调，干燥的土壤有利于葡萄的生长。

This thsis analyzes water-saving irrigation technology economical character, technology providers' behaviors, supplying model, supplying efficiency, system inspiritment and technology application affecting factors on the basis of resource economics, system economics, informition economics and sustainable development theory.

Part II: In accordance with the meaning of Zhuang toponomys, summed up several factors strong associated with the spatial distribution of the Zhuang toponomy,including the altitude, distance to the central cities, and distance to traffic line, whether in the land of paddy soil or irrigation area, the slope and aspect.

第二部分：根据壮语地名的涵义，总结出了海拔高度，与中心城市距离，与交通线距离，是否靠近或在灌溉用地或水稻土范围内、山体坡度、坡向几个与壮语地名的空间分布存在相关性的因子，经过统计分析发现壮语地名和非壮语地名相比较而言在空间分布上具有这样的特点：聚居地海拔高，与中心城市距离远，拥有灌溉耕地的机会多，距离铁路近。

The results of saline water irrigation (1990~1995) showed that the yields of wheat, corn, cotton and grain increased 30% more than those of non-irrigated crops. In the condition of spring irrigation and concentrated rainfall, the soil desalinized in root zone, and the accumulated salt due to saline water irrigation can be leached; reasonab...

三坝浅层地下咸水灌溉试验( 1 990～ 1 995)的研究结果表明，利用 3.0～ 5.1 g/ l的咸水灌溉小麦、玉米、棉花和高粱，均比不灌的增产 30 %以上；在春季河灌和汛期集中降雨淋洗的条件下，作物根层土壤不积盐；实行咸淡水轮灌，增辟水源，改善水质，可获作物增产。

This study mainly focused on the water resource and environmental crisis, which are all caused by agricultural irrigation in Inner Mongolia irrigation area. Based on the balance of total water quantity between ground water, underground water and soil water, a study was made on the water quantity varieties in the headraces and offtakes, and the affection of the water cycle under the human activities was quantitively caculated.

针对引黄灌区所面临的水资源问题及灌溉引起的环境问题，以内蒙古河套灌区为研究对象，从灌溉引水、用水、排水之间的转化关系为切入点，以地表水、土壤水和地下水之间的水量平衡理论为基础，定量研究河套灌区在人类影响条件下的水循环特征。

So the extravagant irrigators of New South Wales will end up with extra water, while their parsimonious counterparts in Victoria will benefit less.

所以，在最后来自新南威尔士州的用水奢侈的灌溉者将会得到额外用水，而那些用水节俭到吝啬程度的维多利亚州的灌溉者却只能获利更少。

In this paper,established the functions of irrigation application efficiency,irrigationdistribution efficiency and water store efficiency according to the parameters of water flowadvance and infiltration for furrow and border irrigation with tailor water condition.

本文提出根据膜孔沟灌的水量平衡原理，由水流行进方程和有关参数，确定入渗方程，并根据灌水均匀度、灌溉效率和储水效率的定义，推导出长沟畦灌溉有排水条件下由行进方程和入渗方程的参数确定的灌水均匀度方程，与沟畦长分段求解方法相比，其误差小于2%。
