| 摘 要： | 在家庭牧场尺度上,对禁牧、休牧等放牧方式下内蒙古短花针茅荒漠草原主要植物种群地上现存量、土壤含水量及其相关性进行研究,结果表明:禁牧区地上现存量为134.56g/m2,与休牧区(129.73g/m2)差异不明显,但均显著高于自由放牧区(84.80g/m2)(P0.05);禁牧、休牧有利于土壤含水量的增加;主要种群的地上现存量受10～30cm土壤含水量影响较大,群落地上现存量与0～40cm土壤含水量有显著回归关系(P0.05),回归方程为Y=2.7245X1+0.0556X2×X3×X4。

| Abstract: | The relationship between the soil water content and the aboveground standing crop in Stipa breviflora desert steppe in banning and delaying grazing in family pasture were investigated.The results showed that the aboveground standing crop of main population under banning grazing was 134.56g/m2,which was not significant different from delaying grazing(129.73g/m2)(P>0.05),but the aboveground standing crop both in banning grazing and delaying grazing was higher than that in free grazing(84.80g/m2)(P<0.05).Banni... |
