| 摘 要： | 以2009年9月乌兰布和沙区植物群落样方调查资料为基础,对其农牧交错带内不同生境的植被特征及其物种多样性进行研究。结果表明：在区域干旱气候的共同背景下,由于受人工绿洲灌溉水分水平运动影响的强度不同,导致该生态交错带内山前洪积扇、人工绿洲周边、绿洲外围植被的组成及其群落多样性差异显著,水平空间尺度上群落变异性大,构成群落...

| Abstract: | In September 2009,the plant community plots were surveyed,and the vegetation characteristics and community diversity in the ecotone from desert to oasis in Ulan Buh Desert were studied,The results showed that due to the dry climate in the region and the different oasis irrigation effect intensity,the composition and diversity of vegetation are significantly different,dominant species composition is different in the ecotone in the alluvial fan,the surrounding oasis and oasis outside.Because of adequate soil ... |
