The middle and lower parts of woodland and grassland had higher soil water contents during rainy season, which resulted from smaller evapotranspiration and more infiltrated water with a lower gradient. However, upslope runoff infiltration was another reason for hillslope with a lower cover ratio, such as bare land.

雨季林草地坡中下部土壤水分含量较高的原因，可能主要与其蒸散较小且坡度较缓导致入渗水量较多有关；但是对于植被覆盖度较低的坡地，坡中下部土壤水分含量较高还与上方来水有较大的关系。

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。

Disaster of embanks often happen under flood and rainfalls. In order to analyze the influences of water level variation and rainfall on the distribution of seepage and embankment's stability, in this paper, the change of seepage field under the condition of different water level or rainfall is studied based on the saturated-unsaturated seepage theory. And the safety factor of embankment's stability is calculated based on the theory of unsatutated-soil shear stress to search for the action of various factors.

堤防岸坡在洪水及降雨的影响下常常发生险情，为了分析江水位变化和降雨条件下，非饱和土体中渗流场的变化情况及其对抗滑稳定性的影响，本文运用饱和—非饱和渗流理论对不同条件下渗流场变化进行模拟，并从非饱和土抗剪强度理论出发，对抗滑稳定性进行计算，探求各种因素对其的不同影响。
