中文摘要	对青海共和盆地内的达连海湖泊流域54个样点进行植被调查及表土花粉分析,研究了植被与表土花粉之间的关系.结果显示:表土花粉组合可反映出该区植被的总体特征;达连海湖泊流域花粉沉积来源于整个流域植被,花粉与主要植被类型之间相关性良好,但不能完全反映出群落的建群种、优势种和盖度等.蒿属和藜科花粉具有超代表性,禾本科表现为低代表性,蒿/藜比具有区域植被生态特点与气候指示意义,在不同的植被区域A/C变化明显;影响达连海湖泊流域表土花粉组合的主要控制因素是风力作用.
英文摘要	In order to investigate the relationship between the surface-pollen and modern vegetation, total of 54 surface-pollen samples from Dalianhai Lake catchment, a sensitive semi-arid zone between the Asian summer monsoon-controlled and the westerly-influenced areas in Northwest China, have been analyzed. The result shows that the corresponding relationship between the pollen assemblages of surface samples and the main vegetation types is better. However, pollen assemblages of surface samples cannot reflect completely the community features of the main, dominant genera and coverage etc.; Artemisia and Chenopodiaceous is over-represented, while Gramineae is under-represented. The A/C (ratio of Artemisia to Chenopodiaceous) changes obviously with different vegetation areas, having regional vegetation ecological characteristics and climate denotative significance. The chief factor controlling the surface-pollen assemblages is wind.
