摘    要: 以科尔沁沙地为研究区,对沙地固定半固定沙丘中典型的灌木半灌木差巴嘎蒿、小叶锦鸡儿和黄柳植被类型区进行了土壤层及植被根系层水分状况的实地调查试验。基于试验结果分析出沙地不同灌木半灌木植物根系形态和土壤水分含量有着很好的对应关系,植物根系发育层对应土壤含水量丰富区,并依据植物的生长形态推断出沙丘中这几种植被的演替规律。从而对干旱沙漠地区植被的恢复与重建提供有益的参考,为西部大开发中进行生态环境治理及“退耕还林还草”提供借鉴。

关 键 词:科尔沁沙地  土壤水分  差巴嘎蒿  小叶锦鸡儿  黄柳

Abstract:This paper regards Horqin sandy land as the studying area.The humidity conditions of soil layer and plant roots are made on-site inspected experiments in the different plants areas(Artemisia halodendron,Caragana microphylla and Salix flavida).The corresponding relationship between the shape of these plant roots and soil water was analyzed on the base of the result of the experiments.Soil water in zone where the plant roots growth well is abundant.According to the shape of these shrubs,the disciplinarian of succession among Artemisia halodendron,Caragana microphylla and Salix flavida was concluded.These conclusions were beneficial and important references for resuming and rebuilding of vegetation and entironment in arid and desert areas.
Keywords:Horqin Sandy Land  soil water  Artemisia halodendron  Caragana microphylla  Salixflavida
