摘要/Abstract

摘要： 植物群落特征是评价高原鼢鼠裸露鼠丘植被自然恢复的重要内容。以甘肃碌曲和夏河的高寒草甸为研究对象,研究了高原鼢鼠鼠丘植物群落自然恢复过程中的特征。结果表明,碌曲调查区和夏河调查区的植被盖度,丰富度指数、多样性指数、均匀度指数、总生物量、多年生禾草,莎草科和多年生杂草类的生物量均随高原鼢鼠鼠丘自然恢复年限增加而增加,1、2年生植物生物量随鼠丘恢复年限增加表现为先增加后降低。碌曲调查区鼠丘恢复时植被盖度,植物多样性和生产力均大于夏河调查区。因此高原鼢鼠鼠丘植被随恢复年限增加的变化趋势趋同,但其过程因地点而存在差异,这为青藏高原高原鼢鼠鼠丘植被的自然恢复管理提供了一定的依据。

Abstract: The characteristics of plant communities are an important method for evaluation of the natural revegetation of plateau zokor mounds. This study investigated the plant community characteristics of plateau zokor mounds at different stages in the natural revegetation process in alpine meadow grassland of Luqu and Xiahe Counties, Gansu Province. It was found that vegetation cover, Patrick index, Shannon-wiener index, Pielou index, total biomass, biomass of perennial Poaceae, Cyperaceae biomass and perennial forb biomass of revegetating plateau zokor mounds increased with time at both Luqu County and Xiahe County study sites. By contrast, the biomass of annual and biennial species on plateau zokor mounds initially increased, and then decreased with time. The vegetation cover, plant diversity and productivity values of plateau zokor mounds in Luqu County were greater than those in Xiahe County. These results suggest that the species secondary succession of vegetation restoration of plateau zokor mounds was similar, whereas the rate of vegetation recovery differed between Luqu County and Xiahe County. These findings provide useful insight into the natural vegetation recovery process that occurs on plateau zokor mounds in the Qinghai-Tibet Plateau.

Key words: zokor-mound, plant functional group, species diversity, productivity, restoration years
