The results showed that there were significant differences among parameters of texture feature of the different land utilization. In the desertification, the mean and variance were comparatively high. The gray level was asymmetry, the contrasts between neighboring pixels were significant; while in water and irrigable land, the mean, variance was a little bit low, the grey level was symmetry; the mean, variance and gray level in the forest and dry land was between the above (desertification and water and irrigable land).

不同土地利用类型之间纹理特征参数差异明显，荒漠化土地的均值、方差值较高，灰度分布不均匀，相邻像元反差明显，内部变化剧烈；水体和灌溉耕地的均值、方差值很低，灰度值均匀，内部变化小；林地和旱耕地信息介于上述两类土地之间。

Although there are many factors that affect the quality of farm products, such as atmospheric fallen dusts, irrigative water and fertilizer application, the quality of earth environment in the farm products area obviously plays the most important role.

虽然影响农产品质量的因素很多，如大气降尘、灌溉水、施肥等，农产品产地土壤环境质量终究是首要的。

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

在覆盖地膜的情况下，给甘蓝进行三水和两水灌溉，都会成为奢侈灌水，并且随着灌水次数的增多，耗水量也增多。

With irrigation came surplus food,which meant that large numbers of people were freed trom the land to pursue nonagrarian specialities—technological development,scholarship for its sake——and war.

The most dramatic example is the Ogallala aquifer,the largest underground water source in the world.this enormous reserve runs through the agriculturally critical high plains states,from south Dakota to central texas.over-pumping for irragation has drained some parts of the aquifer dry and persistent regional drought has stifled refill by underground streams.

过多地采集地下水用于灌溉已经使地下水层的一些地方干枯，而且持续的区域性干旱也使地下河不能补充地下水层。

The results show that buried depth of phreatic water levels has a very important influence on the agricultural environment and transformation between soil water and groundwater.

至1991年底，全市共完成地埋低压石屑混凝土管道输水灌溉面积74kha，占全市井灌面积的1/3，取得年节水量277百万m~3；年节电28.86百万kW·h；年增产粮食100百万kg；年总效益50780千元的经济效益。

But as the special geological condition,irrigation causes a series of problems of agroecological geology,such as landslide,salination and so on.

长时期的引水灌溉使土壤理化性质发生改变，并由此引发了地裂缝、滑坡等地质灾害，同时地下水水位的上升，使地表土壤盐渍严重。
