摘要: 试验研究了不同放牧强度下荒漠草原植物种群株丛面积随季节变化而表现出的变化规律,研究对象主要有短花针茅(Stipa breviflora)、冷蒿(Artemisia frigida)和无芒隐子草(Cleistogenes songorica)。结果表明,短花针茅株丛面积在同一放牧强度下,整体表现为逐月增加的趋势。株丛面积相对较小期出现在6月末,峰值出现在9月。在同一月份不同放牧强度间,短花针茅株丛面积随着放牧强度的增加而增加,各处理间差异显著。冷蒿株丛面积在CK表现为先增加后降低的趋势,峰值出现在8月;在放牧区均表现为逐月增加,峰值出现在9月,在各月份不同放牧强度下,其株丛面积均表现为随着放牧强度的增加而显著降低。无芒隐子草株丛面积变化与冷蒿的变化趋势基本一致。

Abstract: The study- was conduct on the seasonal patternof population bunch area of Stipa brevitlora, Artemisia frigida andpeak value in September. Under ditterent grazing intensities, the bunch area of Stipa breviflora increased with grazingintensity, and there was significant difference between grazing intensities. The bunch area of Artemisia frigida transformedfrom increasing to decreasing in CK block, and the peak value was observed in August. In grazing blocks, the bunch areaincreased month by month, and the peak value was observed in September. Under different grazing intensities, the buncharea decreased significantly with the grazing intensity- increasing in each month. The variation tendency of bunch area ofCleistogenes songorica had no great differences with Artemisia frigida.
