| 摘 要： | 通过在塔城市北山铁列克提春秋牧场设置的轻度放牧(BA1)、中度放牧(BA2)、重度放牧(BA3)和对照四个水平放牧的测定,对不同放牧强度下草地植被的盖度、高度、密度以及生物量的变化进行了研究。结果表明:草地植被群落的主要优势种是草原苔草、千叶蓍、三叶草、早熟禾;不同放牧强度对植物群落具有一定的影响,其中草地植被群落盖度、密度和地上生物量随着放牧强度的增强均呈现下降趋势。

| Abstract: | The paper studies the changes of coverage, height, density and biomasse of grassland vegetation under different levels of grazing intensity by measuring the four levels of grazing, that is, light grazing(BA1), medium grazing (BA2), heavy grazing (BA3) and comparison in Chunqiu Meadow of Beishan Tieliekti. It is found that the main dominant species of grassland vegetation community is grassland sedge, chiba yarrow, clover and kentucky bluegrass, and different levels of grazing intensity can bring certain effects to phytocoenosium, especially, the coverage, density and biomasse of grassland vegetation tends to decrease as the grazing intensity is increasing. |
