地表水灌溉

Chartres提到了印度，在那里他的研究所正在鼓励农民使用地表水灌溉系统补充地下水。

Chartres mentioned India , where his institute is encouraging farmers to use surface water irrigation systems to recharge groundwater .

大同市以往的农田灌溉，多以地表水灌溉为主。

The farmland irrigation of Datong city in the past was mainly depend on surface water irrigation .

矿井水污染的地表水灌溉入渗过程中的水岩作用

Water-Rock interaction during irrigation with polluted water by coal mine drainage

在地下水位埋藏较深（>5m）的地区，以地表水灌溉为主。

While surface water is used to irrigate mainly in the area where the depth of groundwater table is greater than 5 m.

违规取用地表水灌溉，在水资源有限的情况下，从一定程度上损害了公共利益，并对他人不能进行补偿，因而是一种外部不经济的行为。

To some extend , the commonality benefit is harmed if infringing the surface-water irrigation rights without compensation for limited water resources , so this is external diseconomy action .

研究区上游的水-岩作用主要是地表水或灌溉水入渗补给的影响，研究区中下游的水-岩作用主要受蒸发作用的影响；

The water-rock interaction in upstream area undergoes the influence of surface water or irrigation water recharge chiefly , and in middle reaches and downstream area undergoes the influence of evaporation mainly ;

结果表明：地表灌溉水、地下灌溉水水质综合污染指数均小于1，但有升高的趋势；

The result shows that the comprehensive pollution index of the surface and underground irrigation water is less than 1 , but there is a trend of rising .
