查询词典 water and soil

The study show that the frozen earth in this area is mainly silty clay. The content of the dissolvable solt is relative high,which is 12.01%, and the main salinity is NaCL and KCL. The research also revealed that frozen intensity would ascend jumpily when the water contend in the soil reached its optimization( 10.61%) and kept rising,and this phenomena got more obvious with the decrease of the temperature. Between 0C and 10C, the frozen intensity vared very obviously, when the temperature is under -10C, the variety of frozen intensity got gently, and the change is not obvious. The frozen strength was influenced by the solution thickness in the soil hole.when the thickness increased, the frozen intensity decreased.

研究表明：那曲河地区冻土区冻土主要为颗粒较细小的粉质粘土：土样易溶盐含量较高，为12.01％，主要盐分为氯化钠NaCL和氯化钾KCL；该地区冻土土内水分达到最优含水率10.61％并继续增大时，冻结强度有个跳跃式的上升，这种现象随着温度的降低而愈明显；由0℃到-10℃时，冻结强度变化十分明显，温度下降到-10℃以后，冻结强度变化趋于平缓，变化不甚明显；冻结强度受土样孔隙中盐溶液浓度的影响，盐溶液浓度增加，冻结强度减小。

至於七星潭海岸防风林经分析得知，位於防风林带内140 m处减风与减盐效果可高达约90%；再者，叶片与土壤盐份量及空中飘盐量之分布，随水平距离增加而递减，在150 m处皆已降至10 mg/100ml以下；至於林带内平均气温与地温则较林带外高约2℃，土壤含水量较林带外高约0.4%，而气压及相对湿度亦有相同之趋势，但光照度则仅为林带外1/215，日辐射量亦只有1/20。

The process of ecological degradation in the vicinity of Shaoguan Pb/Zn smelter may be summed as: heavy metals and acidic deposits from the waste gas from smelter resulted in the vanishment of the sensitive plant species, increasing accumulation of heavy metals in soils and acidification of topsoil worsened the chemical properties and then shallow-rooted plant, mainly the herbaceous, vanished. With the demolishment of the vegetation cover, increasing water-soil erosion worsened physico-chemical properties of soil and, subsequently, some woody plants disappeared and barren land was finally appeared.

该生态系统的退化过程可以归纳为：来自于冶炼废气的重金属和酸沉降导致了敏感植物的消亡，丧失了对土壤的缓冲保护作用；重金属在土壤表层的积累，酸性物质在土壤表层的增加导致的土壤酸化以及由此引发的有机质与养分的淋溶和重金属及Al的活性增加，加剧植被的快速退化，特别是浅根植物的衰亡；地被层的破坏，导致水土流失和土壤侵蚀加深，进一步恶化表层土壤的理化性质，一些木本植物随之消失，最终形成光板地。

When evaporation was in process, due to low initial water content, most infiltrated water from small intensity and amount of rainfall would be consumed by intensive evapotranspiration during rainy season, and lateral downslope unsaturated flow seldom took place. However, soil water would move downslope by gravitational and matric potential gradients after continuous rainfall.

3在防止蒸发条件下，再分布过程中，土壤水分在重力的作用下有沿坡向下运移的趋势；在蒸发条件下，由于初始含水量一般较低，雨季量小且分散的降雨极易为强烈的蒸发蒸腾所消耗，侧向沿坡向下流难以发生，但在持续的降雨条件下，土壤水分在重力势和基质势梯度的作用下易沿坡向下运移。

So the variety of L21 andLainong9217 should be planted in dry land of high yield,and the variety ofLainong8834 and YD27 in dry land of middle yield,and gaining high yieldand high efficiency.2 The researches on the flag leaf and root system senescence after anthesisand yield were studied in dry land wheat of high yield,the activity of super-oxide dismatase and catalase、and the soluble protein content、Cytokinincontent in wheat flag leaf and root system after anthesisand Cytokinincontent in grain decreased slowly,and the content ofmalondiadehydeand the Abscisic Acidcontent in wheat flagleaf and root system and the Abscisic Acidcontent in grain increasedslowly,meanwhile keep higher root vigor and the root vigor decreased slow-ly,the result would be benefit to delay the senescence and gain high yield.3 The effects of soil thickness on the senescence of flag leaf and root sys-tem、nitrogen distribution and utilization and water consumption law andyield in dry land wheat had been studied in soil column and field.

For each strategy, a corresponding exploitation plan of groundwater was designed. Then each designed exploitation plan (except scheme 3) was put into the model for calculation and simulation. The analysis on the forecasting results every plan indicates that:(1) Shuting down the self-provided wells is the most direct and effective method, playing an important role in the land subsidence prevention.(2) The resumption of compressed soil by groundwater artificial recharge is limited. So the artificial recharge can\'t provide essential effect for the resumption of land subsidence, unless the artificial recharge is much more than the groundwater withdrawal.(3) The method of "adjusting the exploitation stratum of groundwater to the shallow" has an obvious effect on the land subsidence prevention.(4)"Sand wells" can increase the leakage recharge for confined aquifer, and thus can slow and prevent the development of the land subsidence.(5) For the groundwater exploitation in Xi\'an, emergency self-provided wells should be managed according to the well spacing of 1600m, 2000m and 1600m, respectively, in the river terrace area, alluvial-proluvial fan area and loess tableland area to exploit the first confined groundwater. Corresponding individual well yield can be set as 2500m~3/d, 1500 m~3/d and 200 m~3/d. Make emergency self-provided wells pump in the dry year and stop pumping groundwater to restore and conserve underground water sources in average years and wet years. In this way, groundwater withdrawal of 162000m~3/d can be obtained to provide for the supplement of water supply in Xi\'an. As a result, the water supply stress can be released in dry years. The groundwater depression formed in the exploiting year can resume in 3-4 years. At the same time, this exploitation manner will not lead to obvious land subsidence.

本文利用所建的模型预测了现状开采条件下未来20年的地下水位和地面沉降的变化，在此基础上，提出了防治西安市地面沉降的五个地下水开采方案，利用所建的地面沉降模型对各个设计方案其进行了模拟和预报，对预测结果的分析表明：①封停自备井是防治地面沉降最为直接和最有效的对策，对防治地面沉降起着最为积极的作用；②采用人工回灌方法使被压缩的土层得到的恢复是非常有限的，对地面沉降不能起到根治作用，只有回灌量明显大于开采量时才能有一定的效果；③&调整开采层次，在浅层取水&对防治地面沉降的效果十分明显；④布设&砂井&可以增加对承压含水层的越流补给量，从而可以有效地缓解和控制地面沉降的发生和发展；⑤对西安市的地下水开采，可在河流阶地区、冲洪积扇区和黄土塬区分别采用1600m、2000m、1600m的井间距布置应急自备井，分别采用2500m~3/d、1500 m~3/d和200 m~3/d的单井开采量，开采第一承压水，在平水年或者丰水年不开采，涵养地下水源，在枯水年启动这些应急自备井开采，在输出分析范围内共可获得162000 m~3/d(5913万m~3/a)开采量，可以有效地补充西安市的供水水源，缓解供水紧张局面，开采年开采导致的下降的水位可在停采3～4年后得到基本恢复，同时，这种开采方式不会造成大的地面沉降量。
