摘  要：
【目的】以新疆伊犁昭苏马场禾草+杂类草草甸草地为研究对象,研究利用方式对草地植被主要数量性状的影响。【方法】采用放牧+刈割+放牧、放牧+刈割、刈割+放牧、刈割交替等处理。【结果】(1)不同利用方式对植物的重要值影响不同,刈割+放牧(C)、刈割处理样地内的禾草比例高于其他两种利用方式;(2)在高度变化上,各利用方式之间差异性不显著(P>0.05);刈割+放牧(C)、刈割(D)草地群落由于春季均未放牧利用,草地的高度均表现出略高于其他两种方式;(3)在盖度变化上,从三季利用上可以看出刈割(D)优于其他三种利用方式;(4)5～8月四种利用方式在密度变化上差异性不显著(P>0.05),9月,由于放牧与不放牧的差别,刈割(D)利用方式草地群落密度高于其他三种方式(P<0.05);(5)地上生物量变化方面刈割和刈割+放牧利用方式在草地群落地生物量上表现出一定的优势。【结论】初步确定刈割+放牧和刈割利用方式较好,但需要长期的动态监测,方能得到科学结论。

摘  要：
【Objective】 Ggramineous pasture & herbage meadow of Zhaosu Horse Farm in Xinjiang was chosen as the research object.【Method】The main effects of quantitative traits in the grassland vegetation were studied by grazing & cutting & grazing,mowing,grazing & cutting & grazing,mowing alternate use.【Result】 The results showed that:(1) the important value of vegetation was discussed under different utilization modes in that the mode of cutting & grazing and cutting in plot ratio was higher than the other two modes;(2) the changes of height were not significant difference(P> 0.05),cutting & grazing and cutting were slightly higher than the other two modes because the spring time was not used for grazing;(3) the changes in coverage showed that cutting is better than the other three modes in the three seasons use;(4) it can be seen that the density of grassland in four modes was not significant(P>0.05) from May to August.But in September,grassland community density of mowing was higher than the other three due to grazing and not grazing(P<0.05);(5) cutting and cutting & grazing in aboveground biomass has showed certain advantages.【Conclusion】We have get a preliminary conclusion that cutting & grazing and cutting models are better,but in order to get scientific conclusion we need a long-term dynamic monitoring.
