摘要:
 对塔里木河上游荒漠河岸林不同覆盖度下土壤水盐分布规律的研究，为土壤盐渍化防治，干旱地区生态环境重建提供重要依据。通过对研究区不同植被覆盖度条件下（0~0.2,0.2~0.5与0.5以上）的盐渍化土壤进行分层取样，测定其盐分和水分含量，分析在水平方向和垂直方向上的水盐变化规律。结果表明：相同深度土壤盐分随覆盖度的增大呈现减少的趋势，相同土层以5月份盐分含量最高，4月最低；而土壤水分随覆盖度的增大呈增高的趋势，相同土层含水量随时间上没有明显的差异，含水量4月份稍高，6月稍低。在相同覆盖度条件下随着土层由浅到深盐分积累逐渐减少，表层0~60 cm 3个土层随时间推移盐分含量变化明显，其他土壤层次变化不大；而土壤水分与土层深度的关系不明显，随时间变化为4月份土壤含水量相对较多，6月份较低。在不同覆盖度不同土层盐分随水分含量变化规律为4月份覆盖度在0~0.2时，土壤盐分与含水量呈显著负相关，覆盖度在0.5以上时，土壤盐分与含水量呈极显著正相关，其他月份相关性不显著；因此，塔里木上游荒漠河岸林土壤水分、盐分的变化与覆盖度、季节有很大关系。
Abstract:
 In order to provide theoretical basis for soil salinization control and reconstruction of ecological environment in arid area,the variation regularities of soil water and salt distribution under different vegetation coverages in the desert riparian forests in Tarim River upstream were investigated.Stratified sampling method was adopted in salinized soil with different vegetation coverage (0-0.2,0.2-0.5,0.5 or above).Contents of water and salts were measured to examine their variation regularities in horizontal and vertical directions.The results showed within the same soil depth,soil salt content increased with the decrease of vegetation coverage; in the same soil layer,the salt content was the lowest in April and highest in May; soil moisture increased with the increase of vegetation coverage; in the same soil layer,water content had no obvious difference with time,soil moisture was a little higher in April,a little low in June.Under the same coverage,the soil salt accumulation gradually reduced with soil depth; significant variations of soil salt content with time were observed in 3 layers within the depth of 0 to 60 cm ,while it was not significant for other soil depths; the relationship between soil moisture and soil depth was not significant,the moisture content in April was relatively high,and low in June.In April,significantly negative correlations were found between soil salt and water under the vegetation coverage of 0-0.2 and the correlation was the most significantly negative under the coverage over 0.5,and no significant correlations were found in other months.It was concluded that the soil moisture and salt variations were closely correlated with vegetation coverage and season in the area studied.
