首先生态垫能够显著降低沙地0~15 cm的土壤温度，日均温可降低2.06~4.56℃，有利于沙地高温条件下减少土壤蒸发；在连续无降雨的情况下，生态垫下各层次的土壤含水量都高于流动沙丘裸地，尤其是15~30 cm含水量相对稳定，人工植被建立后，其保存率、生长量较流动沙地均有较大幅度的提高。

Ordosica biomass and density was dependant on that of soil moisture, and in particular, there existed a significant positive correlation between the biomass and the moisture, indicating that on semifixed dune, soil moisture played a decisive role in the spatial heterogeneity of plant population.

由于沙丘地形对降水量的再分配在土壤湿度分布中的作用，土壤湿度和油蒿种群空间异质性相互作用的结果为地形的缀块性→土壤湿度分布的缀块性→油蒿种群分布的缀块性→油蒿生物量和密度的缀块性。

Temporal and spatialcorrelation of Soil moisture under vertical direction was affected by some factor such asmeteorology, land use and fertilization measures. All siol moisture in different layers hastemporal and spatial correlation when soil moisture fluctuates of surface layer becausestability, but influence ability of each factor is not the same. For example, meteorologyhas most strong impact on temporal and spatial correlation of soil water content.

在气象条件较稳定的情况下，不同植被覆盖和不同施肥措施下各土层含水量之间都具有较强的时空相关性，随着气象条件波动加剧，各土层土壤含水量的时间相关性和空间相关性都降低；植被因素相对气象条件对各土层含水量的时间自相关性影响较小，而对各土层土壤含水量之间的空间相关性影响较大，裸地和农田各土层土壤含水量之间的空间相关性相对林地和草地较弱；不同的施肥水平都削弱了土壤各土层含水量的时空相关性。

Planted forests can deplete deep soil water, forming an obstacle to sustainable land use in the semi-arid area of Loess Plateau. The purpose of this study was to examine effects of grazing and cropping on replenishment of deep soil water where forest plantations had depleted soil moisture at depths of 2～9.9 m. We compared soil moisture on plantation plots with that on plots where plantations were replaced by crops, grazed grassland, and ungrazed grassland seperately.

为了研究黄土丘陵半干旱区人工林迹地土壤水分恢复情况，该文以正在生长的人工林土壤水分含量为人工林迹地土壤水分恢复的起点，并分别以持续农地和持续放牧荒坡的土壤含水量为林后农地和草地土壤水分恢复的上限，对位于黄土丘陵半干旱区绥德县境内的人工林迹地土壤水分恢复情况进行了研究。

The result showed that Wote and PAM increased the average temperature of the earth's surface, temperatures of 10cm soil, 20cm soil and the lowest temperature of the earth's surface, but reduced the highest temperature of the earth's surface in reviving phase. Soil moisture was increased by using Wote and PAM, and the soil moisture of 0-30cm soil in florescence and fruiting phase was also increased.

结果表明，施用沃特和FAM降低了西瓜缓苗期的地表最高温度，提高了地表的平均温度、最低温度及10cm土层和20cm土层的土壤温度，增加了土壤的含水量，特别是开花坐瓜期0~30cm土层的土壤含水量。

Soil moisture content varied abruptly in the ecotone zone, hut presented linear distribution in both grassland zone and farmland zone. The average soil moisture content in grassland was about 1 gg^(-1) higher than that in farmland, which was mainly caused by the decreased capillary moisture capacity of farmland.

其中农田－草地复合功能区的土壤含水量变化剧烈，而草地功能区与农田功能区内土壤水分基本呈线性分布；草地生态系统土壤平均含水量比农田高约1 gg^(-1)，这主要是由于草地开垦为农田后风蚀等作用而引起的土壤毛管持水力下降所致。

To control the ground-water table on irrigated lands is vitally important in arid and semi-arid regions. In order to determine the standard of water table control, considerable attentions were paid to the "critical depth"(or "safe depth") of ground-water table. The salts accumulate in the top soil if the water table is not deeper than this depth. The conditions that the salts accumulate in any layer of the soil owing to the movement of soil moisture are:(1) the supplement of soil moisture from neighboring...

本文分析了地下水补給情况下土壤水分的形态和不同形态的水分在土壤中运行和蒸发的一些特点，论証了毛管水联系破裂含水率等土壤水分形态指标与土壤水分运动和土壤积盐状况的关系，探討了次生盐碱化发生的地下水临界条件，提出了地下水临界深度的确定方法，并且对現有的临界深度的确定方法进行了討论与比較。
