中文摘要	青海省都兰县青冈滩2006年开始封育.采用样线法对封育区内的群落结构、种类组成、物种多样性等进行调查,结果显示: 2007-2009年雨水丰沛,平均年降雨量分别275.2,234.3,289.1 mm,均大于多年平均年降雨量 188.7 mm. 2007-2009年封育区的植被覆盖度、生物量增加,封育区2009年植被覆盖度和生物量分别达到了 34%,3 495 kg/hm2; 群落平均高度2007-2008年增加了近67%,2009年与2008年基本持平; 区内的植物种类在 2008年达到顶盛,物种数量达到了31种,物种多样性D,H分别达到8. 682,2.538.由于受2009年6月降雨稀少影响,2009年的物种数量减少了12种,大部分植物种的重要值下降,但是减少的植物种多为非主要种,主要种如猫头刺、戈壁针茅、碱韭以及白刺的数量和重要值保持稳定.2009年封育区物种多样性较2008年也有所减少
英文摘要	The line-transect method was employed in a survey to investigate the community structure, species composition and species diversity in Qinggang wetland of Dulan county, Qianhai, where enclosure has been practiced for regeneration starting since 2006. The results showed that the rainfall of 2007, 2008 and 2009 was abundant, being 275. 2 mm, 234. 3 mm and 289. I mm, respectively. higher than the average annual rainfall (188.7 mm) in the region. The vegetation coverage and biomass’of the fenced area increased steadily and reached 34% and 3495 kg/ha in 2009. The average height of the community increased by about 67% in 2008, compared with 2007, and remained little changed in 2009. Plant species in the region grew vigorously in 2008, the number of species reached 31 and the species diversity indicators D and H were 8.682 and 2.538, respectively. Due to the scarce rainfall in June of 2009, the number of species was reduced to 12 and the importance value of most plant species decreased. But the reduction occurred largely in non-major species, the number and importance values of major species such as Oxytropis aciphylla Ledeb, Stipa tianschanica Roshev. var. gobica (Roshev.) P. C. Kuo et Y. H. Sun, Allium polyrhizum Turcz. ex Regel and Nitraria tangutorum Bobr remained stable. Species diversity in the fenced area also decreased in 2009
