| 摘 要： | 温带荒漠的积雪沿灌丛始融，并以灌丛为中心形成融雪漏斗，导致融雪水向灌丛基部汇集。观测资料表明：通过灌丛对融雪水分布的反馈，使灌丛周围的沙层含水量明显增加，为裸沙区的152.1一228.9%，从而提高融雪水的利用率并改善灌丛自身的供水条件，对荒漠植被的分布格局亦起一定影响。

| Abstract: | In the temperate deserts, the snow nearest a plant melts at first then the snow around it follows. And as the water flow passage to soil appears, which centres at the plant and collects the snowmelt to water the plant, the depth of the wet sands is increased.Data on sampling area indicates that the sand moisture around the plants incresses obviously: the amount of snowmelt collected by the plant root zone is 56.77mm, which is 228.9% of the snowmelt received by bare area. The utilization efficiency of snowmelt for desert plants is improved as the moisture moved from upper soil layer to deep soil. As a result, the distribution pattern of desert plants is arranged. |
