摘　　要：利用文献调查法、访谈调查法与实地调查法，对1986～2012年期间西鄂尔多斯地区珍稀濒危药用植物资源及其多样性的时空变化特征进行比较研究，旨在为西鄂尔多斯濒危药用植物资源的有效保护和永续持续利用提供科学依据．结果表明：1986年到2012年，该地区的8个主要药用植物群落在Simpson指数、Shannon-Wiener指数和群落盖度上有明显差异．生物多样性在荒漠草原群落呈现下降趋势，在草原化荒漠群落中变化不大，同时，群落盖度在草原化荒漠却有所增加．由此可见，荒漠草原和草原化荒漠生物多样性保护工作已经取得一定成效，但仍需高度重视和加强．In order to provide a scientific basis for sustainable utilization and conservation of rare and endangered plants in West Ordos,plant community diversity in 2012 was compared with that in 1986 and 2000 by documents,interview and field investigation. Our results indicated that the 8 major types of medicinal plant communities showed significant differences in Simpson index, Shannon-Wiener index,and coverage, but similar richness. From 1986 to 2012, the biodiversity and coverage had changed obviously in different medicinal plant communities. The biodiversity showed a decrea-sing trend in desert-steppe, but no changed in steppe-desert, whereas the coverage increased in steppe-desert. It is recommend that great attention should be paid to the ecological conservation of the desert-steppe as well as to species diversity of steppe desert and desert-steppe.
