大青沟是内蒙东部哲里木盟甘旗卡沙土地区的一条沙沟。这条沙沟属于西辽河流域支流——柳河的小支。在沟沿的外边是一片起伏的沙丘,而沟内森林被复,沟底还有很浅的流水。在广大的沙土地区,能保留下这块森林,除了历史原因,还由于特定的生态条件。研究沟内分布的森林植物与生态条件的关系,对于在沙土地区人工造林,恢复植被,从而改变沙区的面貌,有着重要的意义。 本文是研究大青沟不同森林植物群丛下,土壤中微生物的生态分布与植物和土壤相互关系的初步结果。
Daqinggou is a sand ditch in the Khasabu area of Ganliu Banner, Zheli, Inner Mongolia. This sand groove belongs to the tributary of the West Liaohe River Basin - a small branch of Liuhe. In the ditch along the edge of a dune ups and downs, while the ditch forest complex, ditch bottom there is a very shallow water. In the vast sand area, this forest can be preserved, except for historical reasons, but also due to specific ecological conditions. Studying the relationship between the distribution of forest plants and the ecological conditions in the ditch is of great significance to the afforestation and restoration of vegetation in the sand area, thus changing the appearance of the sand area. This article is a preliminary study on the relationship between the ecological distribution of microorganisms and the relationship between plant and soil in the communities of Daqinggou under different forest flora.
