中文摘要	为揭示平原水库周边无灌溉盐荒地及防风林生长区水盐分布特征,在沙漠绿洲区多浪水库南库区周围布设了地下水监测井和土壤监测点,进行了为期2 a的逐月地下水埋深监测和土壤含水率及含盐量的定点取样测定试验。结果表明:库区周边盐荒地地下水埋深随监测时段变化变幅不大,2 a内均值为1.28 m;不同土壤含水率整体随土层深度增加呈升高趋势,其中60 ~ 100 cm的土壤含水率较其他土层波动较大。2 a间盐荒地的土壤含盐量在0.48~8.86 g · kg~(-1)之间变化,不同土壤总盐含量随土层深度增加呈减小的趋势,0~40 cm 土层含盐量变化较为明显,具有显著的盐分表聚现象,其中,防风林地土壤含盐量在0~40 cm 土层内较天然生态林地明显降低。
英文摘要	In order to reveal the distribution of soil water and salt in the non-irrigated saline wasteland and the growth zone of the windbreaks surrounding a plain reservoir, the groundwater monitoring wells and soil monitoring sites were distributed around the south area of Duolang Reservoir in a desert-oasis region. The monitoring of monthly groundwater depth and soil moisture and salt contents in a 2-year period was conducted. The results showed that the groundwater depth under saline wasteland in the study area was slightly changed during the monitoring period, and the average was 1. 28 m. Soil moisture content was increased with the increase of soil depth,and soil water content at 60 - 100 cm depth was higher than that at other soil layers. Soil salt content in the saline wasteland varied in a range of 0.48 - 8. 86 g · kg~(-1), and the total soil salt content was decreased with the increase of soil depth. The soil salt content at soil depth of 0 -40 cm changed most significantly,and a salt accumulation occurred at this soil layer. The soil salt content under windbreaks was significantly lower than that under natural ecological forest.
