| 摘 要： | 本文在库布齐沙漠西部,于2004年从植物萌动前的4月末开始到植物生长结束后的10月为止,对不同立地条件梭梭人工固沙林以及流动沙丘,分别进行了沙层水分的定点观测,结果表明,不同立地梭梭植物群落的土壤水分时空分布格局不同,即表层(0-10 cm)土壤含水量较低,为土壤水分低值层;中层(10-115 cm)土壤含水量逐渐升高,且波动剧烈,为土壤水分活跃层;下层(115cm以下)土壤含水量高,波动幅度小,为土壤水分相对稳定层。土壤含水量的季节变化可分为三个阶段,4~5月的土壤水分弱失水阶段,6~8月的土壤水分消耗阶段,9~10月的土壤水分缓慢恢复阶段。 |

| Abstract: | From April to October of 2004,the observations were done in west of Desert KuBuQi.This research was about the soil moistures under different soil's condition,artificial sand-fixing Haloxylon ammodendron vegetation and flowing sand dune.Surface layer(0-10cm) of soil contains less water,and it's called lower moisture floor;middle floor(10-115) of soil contains more water and fluctuates is sharply,it's called activity soil containing water floor;under layer(115cm below) of soil contains the most water,and fluctuates less,and this is called comparatively stable floor.Seasonally change of soil water can be divided to three phases,April and May is the stage of loss of water,June to August is consuming stage,September to October isslowly resuming stage. |
| Keywords: | artificial Haloxylon ammodendron forest soil moisture's dynamic rule KuBuQi desert |
