灌溉

It can provide some theoretic gist for resource value of water and soil in sandy land to indicate the change and law of soil moisture character, as well as the water circulation and balance mechanism in sandy land, at the same time, it have important practical significance to protect limited water resource, improve using efficiency of water resource,control desertification, choose and educate sand binding plant, renew and restore degraded ecosystem, as well as the economy benefit of irrigative agriculture and intending trend of development.

揭示沙地土壤水分特征的变化规律以及沙地水循环和平衡机理，可以为沙地水土资源评价提供一定的理论依据，同时对于保护当地有限的水资源和提高水资源的利用效率，以及沙漠化防治，固沙植物的选育，退化生态系统的恢复与重建，灌溉农业的经济效益和未来的发展趋势都具有重要的实践意义。

Water- consumed was increased with irrigation times, if the irrigative water under PFM was the same as no PFM.

Under the current (1996) conditions of planned irrigative and municipal water supply of Shihmen Reservoir, inflow discharge at the damsite, estimated flows at downstream control points and other associated data, the annual shortage ratio and shortage index through reservoir operation simulation are called the basic shortage ratio and shortage index. These two numbers are the criteria to evaluate the reliability of water supply from the Reservoir.

摘要探讨石门水库在现况(民国85年)灌溉及公共给水计画配水情况下，以石门坝址之流量纪录及其下游控制点之推估流量，配合水库相关资料，经由所建立之水库运转程式，模拟其年平均缺水率及缺水指数，此称之为基准缺水率及缺水指数，以作为水库供水可靠度之比较标准。

Soil organic matter is isotropous in north-south and northeast-southwest direction with stronger spatial correlation, and is anisotropic in the southeast-northwest and east-west direction with larger spatial variability.

结果表明，以土壤有机质和农用地类型为协因子的球状模型Cokriging总体插值精度最高，试验区内土壤有机质分布格局是四周丘陵和水库区含量较低，巴江河两岸的平原地区、西南角的山前冲积平原含量较高，这也是灌溉水田密集的区域；试验区内土壤有机质含量菜地分布比较均匀、空间相关性很强，而水浇地分布差异较大、空间变异性较高；土壤有机质分布在南北、东北-西南两个方向相关性较强具有各向同性特征，在东南-西北、东西方向具有各向异性特征，受到随机因素的影响变异性较大。

A number of modern, large-scale water conservancy projects represented by Kizil Reservoir and the Ulug Ata key water control project in Hotan and large numbers of trunk and branch canals, as well as seepage control projects have been built, thus rapidly increasing the amount of water diverted, the capacity of the reservoirs and the well-irrigated area in the whole region.

以克孜尔水库、和田乌鲁瓦提水利枢纽等为代表的一批现代大型水利工程和大批干支渠及其防渗工程的建成，使全区的引水量、水库库容和有效灌溉面积迅速增加。

Love is lire a plant; it needs to be watered every day before it blossoms

感情就像植物，要每天灌溉，才能开花

Based on microlevel data collected in Gansu and Inner Mongolia, the method of data envelope analysis was employed to examine the efficiency of agricultural water utilization, the logical relationship between water use efficiency and water right transfer was analyzed to examine the preconditions for agricultural water transfer against transitional background of Chinese economy.

本文利用甘肃、内蒙2省典型灌区432个农户的实地调研数据，基于数据包络分析方法，对农户灌溉用水效率与农业水权转移的内在逻辑关系进行系统分析，以探索中国转型经济条件下农业水权转移的条件。
