荒漠绿洲过渡带植被与地下水及盐分的关系

Relationship Between Vegetation,Groundwater and Salinity in Desert Oasis Transition Zone

为了了解荒漠绿洲中过渡带的植被与地下水及盐分之间存在的关系。利用巢式取样法测定植被的吸光值、全氮均值,获得地下水和盐分的实际变化情况。结果显示,吸光度越高,全氮均值越高,表明地下水的分布状态越均匀,总盐分较低,此时荒漠绿洲过渡带的植被生长状况较好;反之成立。

In order to understand the relationship between vegetation,groundwater,and salinity in the transitional zone of desert oases.Using nested sampling method to measure the absorbance value and total nitrogen mean of vegetation to obtain the actual changes in groundwater and salinity.The results showed that the higher the absorbance,the higher the mean value of total nitrogen,indicating that the distribution of groundwater was more uniform and the total salt content was lower.At this time,the vegetation growth in the desert oasis transition zone was better;The opposite was held true.
