| 摘 要： | 通过对昭苏马场丘陵山地草原冬草场、春秋草场、河滩阶地草原春秋牧场、沟谷平地人工草地、前山带低山丘陵草甸草原冬草场进行定位观测研究,结果表明:草地年度内地上生物量变化随年度的季态变化而变化,而草地产量的增减变化幅度与草地的草群组合、利用状况及所处的位置有关。

| Abstract: | The winter and spring-fall rangeland in mountain and hill region,spring-fall rangeland of terrace by the river,man-made grassland of gully flat land and winter rangeland of low mountain and hill meadow grassland in foremountain zone in Zhaosu Horse Farm were studid by fixed position observation.The results showed that the aboveground biomass of grassland was changed with annual seasonal change in a year;but the change range of grassland yield had something to do with grass-groud combination,utilization condition and grassland position. |
