中文摘要	2008年在新疆北部准噶尔荒漠的莫索湾地区,通过调查78个植被样方,探讨了短命植物对人为干扰的响应特征。结果表明: 区内植物种类成分较为简单,相似程度较高。短命植物呈斑块状集聚分布。从沙漠腹地到绿洲边缘,短命植物呈现规律性变化,较高的丰富度指数和多样性指数出现在沙漠腹地和过渡地带。物种多样性指数与干扰因子数之间的灰色综合关联度均在0. 7以上,表明干扰在物种多样性变化中的重要作用。垦殖、放牧和工程等大面积、高强度的扰动,使得在荒漠中生长繁盛的短命植物物种骤减。于此同时,荒漠腹地有车辙等碾压痕迹的地方,形成较小范围的积水微环境,为短命植物的生长提供了有利条件。
英文摘要	In 2008,we monitored communities of early spring ephemeral in 78 quadrats in Mosuowan area in Dzungaria Desert,northern Xinjiang,soil and human disturbance data were also collected. We found that most of ephemerals extended out collectively as mosaic patches,with the higher importance values appearing in desert hinterland and transitional zone. And there were few variations in the classification of the ephemerals,which were similar in ecological characteristics with each other,and emerged in an overlapping way due to the differences in the micro-habitats. According to the grey relationship matrix analysis between species diversity and degree of disturbance,there was close relationship between the species diversity and the number of disturbance in the Dzungaria desert. The integrated grey relation degrees were all above 0. 70. These values indicated that human disturbance was an important factor in the environmental factors which influenced the changing of species diversity. And with the aggravation of the desert reclamation,grazing and desert engineering in large scale and high intensity,the number of the ephemerals suddenly decreased in the oasis boundary. We found that in certain areas,there formed some accumulation of water in a small range caused by the rolling of the rutting. In these micro-habitats,some ephemerals have showed clumped distribution.
