在焉耆盆地大规模的土壤取样、试验分析盐分数据的基础上，采用地统计学的方法对研究区的土壤盐分进行了空间特征变异分析，并采用普通克里格插值法制作出焉耆盆地的土壤盐分空间数字地图，结果表明：研究区各层土壤盐分变异系数均大于100%，具有强空间变异性；对土壤盐分进行半方差函数计算分析，发现拟合的理论模型均为球状模型，各层土壤盐分表现出强烈的空间相关性；土壤盐渍化程度在水平方向的分布与地形地势的关系密切，在垂直方向则表现出强烈的表聚特性。

Field survey, sampling and testing were used to discuss the characteristics of soil water content between different subsidence stages. The results show that after mining collapsing, the soil water content and soil water storage capacity of subsidence area is obviously less than the nature area, especially for the fissure zone. It is indicated that the collapsing fissures are extremely disadvantageous for soil water-holding capacity and the conditions of vegetational cover on the subsidence area also confirmed this result.

现以神府东胜煤田为研究背景，选择两个主要塌陷阶段分布区大柳塔矿区双沟村原农场和补连塔矿区原补连沟村作为研究区，采用野外勘查、取样测试与室内参数分析综合研究的方法，对采矿塌陷不同阶段表层包气带土壤水分进行对比分析，结果表明，采矿塌陷后，塌陷区尤其是塌陷裂缝区的土壤含水量与土壤储水量值均小于未塌陷区，说明塌陷裂缝对土壤的持水作用具有非常不利的影响，塌陷区与未塌陷区的地表植被覆盖情况也证实了这一点。

Growing sweet corn in summer could absorb redundant nutritional ingredients largely in the soil, but the number of fungi was high and the ratio of B/F is not obvious compared with CK. On the contrary, planting leafy vegetables had no obvious effect on the composing of soil microbe and the decruce of the number of pathogen of cucumber, although it could reduce the content of salty in the soil. The crop green manure of villose vetch could reduce the content of salty in the degree, but the sum of microbe in the soil reduced a little.

夏季休闲期间种植甜玉米可大量吸收土壤中多余的营养成分，但真菌数量偏高，B/F值与对照相比相差不大；种植速生叶菜虽然能降低土壤盐分含量，但对降低黄瓜致病菌数量和改善微生物区系组成方面无显著效果；豆科作物毛苕子在一定程度上降低了土壤盐分含量，但土壤微生物总量有所减少。

Results of eight investigations make use of the soil experience and analysis form the disaster area of 921 earthquakes, The result of soil investigation and analysis form the disaster area of 921 earthquakes, Understanding such as: 1. The recommand degree depth of drive stake is 40% of stake length for stake and wattling method on dry soil condition. And 58% of stake lengths on unsaturated condition. And 67% of stake length on soil saturated condition.

本研究乃以8个涵盖921集集地震灾区之区域地质样区，采取土样进行试验分析与计算，经研究调查结果得知，乾土时打桩编栅工法桩材的贯入深度建议为桩材长度之40%，半饱和时的桩的贯入深度建议为桩材长度之58%，完全饱和时桩贯入深度建议为桩材长度之67%。

In many cases, the effect of suction in a partially saturated soil is ignored at all; very often, the soil above the ground water table is simply treated as a dry soil or as a saturated soil.

现今处理部分饱和土壤之力学模型及地工相关问题，多仅描述其排水条件下之力学行为与工程问题，甚或更仅将土壤简化为饱和土壤来分析之。

The results show that 42.86% topsoil samples are polluted by Cadmium, soil synthesis pollution index is moderate, Cadmium pollution degree of topsoil correlate with the environment of sampling sites. The results also show that exchangeable Cd, carbonate-bound Cd, organic-bound Cd and residual Cd are found in all soil samples except for Fe-Mn oxide-bound Cd. Furthermore, the concentration of exchangeable Cd and carbonate-bound Cd, both which have high biological validity, is high. Humus has a certain correlation with exchangeable Cd, organic-bound Cd and residual Cd, and has no obvious correlation with other chemical speciations. Any chemical speciation of Cd has no obvious correlation with pH and total Fe of soil samples. Cadmium in topsoil can be eluviated by acid solution, the quantity of Cadmium eluviated by redistilled water is little. With the rise of pH of eluviating solution, eluviated Cadmium quantity decrease. For the same soil sample, the lower pH value of eluviating solution is, the more fast the Cadmium is eluviated, and the more thequantity of Cadmium is eluviated.

研究结果表明：成都市表生土壤样中有42.86%受镉污染，镉综合污染水平达中度污染，成都市表生土壤镉污染程度与采样点周围环境表现出一定的相关性；除铁锰氧化物结合态镉在部分土壤样中未检出外，所有土壤样均含有可交换态镉、碳酸盐结合态镉、有机结合态镉、残留态镉，且生物有效性较高的可交换态镉和碳酸盐结合态镉占总镉量比例较高；成都市表生土壤中的腐殖质与可交换态镉、有机结合态镉、残留态镉有一定相关性，与碳酸盐结合态镉、铁锰氧化物结合态镉相关性不显著；各形态镉与土壤pH值和全铁的相关性均不显著；土壤中的镉可被酸溶液淋出，重蒸馏水淋出镉量十分微小；随着淋滤液pH值的升高，土壤样的镉淋出量下降，且0～5小时时段的镉淋出量占镉总淋出量比例下降，5～30小时时段的镉淋出量占镉总淋出量的比例上升，对同一土壤样而言，酸度大的淋滤液比酸度小的淋滤液淋出镉速度更快，淋出镉量更大。

Results indicated that furrowing can make the soil of the ridge looser and soil porosity larger, so favoring the aeration and water permeability of soil, enlarging the storage capacity of soil water.
