中文摘要	以野外植被调查、物种多样性计算和土壤含水量测定为基础,分析了榆靖沙漠高速公路沿线植被特征,物种多样性指数及其与土壤含水量之间的关系。结果表明:(1)研究区主要物种共计16科39属49种,油蒿为分布最广泛的优势种,植物群落以油蒿群落最为常见;各区域重要值大于0.1的物种中灌木和半灌木占优势。(2) 12个小研究区的Shannon指数平均值1.42~2.05,其中研究区E最高,研究区G最低;由于黄土覆盖区(采样线5)土壤养分含量良好,植物生长发育良好,植被覆盖度较高,其Shannon指数和Sorenson相似性指数高于其他3种生境条件的研究区。(3)Pielou指数与0~10 cm土层的含水量呈显著负相关,而物种丰富度与20~30 cm土层的含水量呈显著正相关。
英文摘要	Based on the research of field vegetation,the calculation of species diversity and the determination of soil moisture content, the vegetation feature along Yujing desert highway, species diversity index and its relationship with soil moisture content were analyzed. The results indicated that: (1) there were mainly 16 families, 39 genera and 49 species living in the study area. Artemisia ordosica was the dominant species which was most widely distributed,and its community was the most common one among plant communities. Shrubs and semi-shrubs were dominant species among the field vegetation whose important value was larger than 0.1 in each region. (2) The average of Shannon index in twelve small study areas varied from 1.42 to 2.05. Among these small study areas,the highest average was in study area E,while the lowest was in study area G. Because of favorable soil nutrient content,well-grown plants and high vegetation cover in loess-covered area (sample line 5),whose Shannon index and Sorenson similarity index were higher than other three study areas with three kinds of ecological conditions. (3) Pielou index was significantly correlated with the soil moisture content of soil profile in 0-10 cm, so did the richness of species to that of soil profile in 20-30 cm.
