荒漠草原植物种群株丛面积对放牧强度的季节性响应
The seasonal response of population bunch area to grazing intensity in desert steppe
摘要
Abstract
The study was conduct on the seasonal pattern of population bunch area of Stipa breviflora , Artemisia frigida and Cleistogenes songorica under different grazing intensities in desert steppe. The results indicated that the bunch area of Stipa breviflora showed increasing trend by month in the same grazing intensity, and the lower value was observed in June, the peak value in September. Under different grazing intensities , the bunch area of Stipa breviflora increased with grazing intensity, and there was significant difference between grazing intensities. The bunch area of Artemisia frigida transformed from increasing to decreasing in CK block, and the peak value was observed in August. In grazing blocks, the bunch area increased month by month, and the peak value was observed in September. Under different grazing intensities, the bunch area decreased significantly with the grazing intensity increasing in each month. The variation tendency of bunch area of Cleistogenes songorica had no great differences with Artemisia frigida.关键词
