摘要	本文对青海湖北岸的植被演替规律进行了研究。首先，依据对青海湖北岸植物群落的踏查和对鸟岛、大通山及海晏湾三个地区的系统取样调查，说明了湖北岸植被的类型及分布规律。主要包括如下八种植物类型：1. 沼泽草甸，2. 草甸，3. 温性草原，4. 高寒灌丛，5. 高寒草甸，6. 高山流石坡稀疏植被，7. 沙生植被，8. 栽培植被。然后，通过组平均法，将湖北岸三个地区的植物群落分为24个群丛，并分析了各个群落的多样性及演替度和生态优势度。最后，用空间序列推断时间序列的方法，重点利用群落数据和环境数据对青海湖北岸的沼泽草甸→草甸、温性草原、高寒草甸、高寒灌丛等几个主要植被类型和综合演替进行了主分量分析（PCA排序），说明了它们的演替顺序，同时还讨论了它们的顶极群落。我们将青海湖北岸的植被演替分为湖滨平原植被的演替和山地植被的演替。后者包括高寒草甸和高寒灌丛的演替；前者包括沙生植被、温性草原和湖水退缩后的植被演替。湖水退缩后的植被演替中又包括了沙生植被、沼泽草甸→草甸和综合演替三种情况。
其他摘要	Qinghai Lake is the largest inland saline lake in china. It is situated in the northeastern part of the Qinghai Xizang Plateau. Study has done on law of vegetational succession in the north shore of Qinghai Lake on the paper. First, according to tread to plant community in the north shore of Qinghai Lake and systematical sampling to three region-birds island. Datong Mountains and Haiyan Bay, show vegetation type and law of distrbution in the north shore of the Lake. Mainly, include: 1. swamp meadow, 2. meadow, 3. temparture steppe, 4. alpine shrub, 5. alpine meadow, 6. apline drift stone slop sparse vegetation, 7. psammophytic vegetation, 8. cultivated vegetation. Second, according to group-average method, plant communities were divided into twenty four association in three region of in the north shore of the Lake, moreover, analyse biological spectrum diversity, degree of succession and ecological dominance of a kind of community. Finally, according to method that spare order infer time order, with community data and environment data, analyse a serveal main vegetation type that include swamp meadow meadow, temperature steppe, alpine, meadow alpine shrub and so on, and syntetio succession in the north shore of Qinghal Lake with PCA ordation, show their succession order, moreover, discuss their climax. We shall divid vegetational succession in the north shore of Qinghai Lake into vegetational succession of lakeside plain and hilly area, the latter inoludes succession alpine meadow and alpine shrub; the former include vegetational succession of psammophytic vegetation, temperature steppe and when lake water shrink back. Vegetational succession when lake water shrink back, it include psammophytic vegetation, swamp meadow-meadow and synthetic succession.
