| 摘 要： | 利用地统计学方法及ArcGIS中的Kriging空间插值法对瓜州绿洲胡杨林下土壤含水量的空间变化规律进行了研究.结果表明:在垂直方向上,QZ、SG和BL三个样地的土壤含水量随深度的增加而增加,TG样地,由于土壤板结,导致其含水量随深度的增加呈减少趋势.瓜州绿洲胡杨生长阶段与其林下土壤含水量呈负相关关系,且土壤含水量越向...

| Abstract: | The spatial variations of soil water content in the populus euphratica forest in Guazhou Oasis were analyzed by using methods of Statistics and Kriging interpolation.The mainly results showed:In vertical direction,the soil water contents of QZ、SG and BL increase with the depth of sample,and the soil water content of TG increases with the depth of sample in 0-80cm,but it reduces with the depth of sample in 100-120cm.The soil water content of the Populus euphratica reduces as the age of the Populus euphratica.The extent of soil water content in QZ is less than others,it is showed that human activities impact more on soil water content and the influence of irrigation is primary in Guazhou Oasis.In space,the soil water content of the Populus euphratica in Guazhou Oasis increases from southeast to northwest. |
