| 摘 要： | 为揭示平原水库周边无灌溉生态林地水盐分布特征,2013-2014连续两年开展生态林地的地下水埋深、矿化度、土壤含水率及含盐量逐月监测。结果表明:周边生态林地地下水埋深变化范围在1.18~1.82m之间,水位变化幅度不大,地下水位随季节性变化较小;地下水矿化度变化范围在0.42~4.92g/L之间,呈周期性变化。土壤水分含水量整体随着土层深度的增加而增加。土壤总盐含量在0.24~8.9g/kg之间变化,其中10~40cm土层含盐量变化最为显著,具有明显的盐分表聚现象。

| Abstract: | To reveal the plain reservoir surrounding ecological forest land without irrigation water salt distribution characteristics ,the project is 2013-2014 for two consecutive years to carry out the ecological forest of groundwater buried depth ,salinity ,soil moisture content and salinity monitoring from month to month .Preliminary study showed that ecological forest surrounding the groundwater depth range between 1 .18 to 1 .82 m ,the water level change is not big ,weak underground water level along with seasonal changes . Changes in salinity range between 0 .42 to 4 .92 g/L in periodic change of the ecological forest .Soil water moisture content increases with the increase of soil depth as a whole .Soil total salt content in the 0 .24~8 .9 g/kg ,including 10~40 cm soil total salt is the most significant change ,has the obvious phenomenon of table salt together . |
