摘  要:
采用样地调查方法,通过对不同封育类型的植被特征和其对应的土壤理化性质测定,分析了其对植被生长的影响。方差分析结果表明,在不同类型封育区,土壤紧实度是影响植被生长状况的主要因子之一。进一步回归分析表明,土壤紧实度与植被的生物量和盖度呈负相关。当土壤紧实度变化在2.0~3.0 kg/m2时,植被的盖度和生物量均较高。

摘  要:
By means of plot investigation methods and through surveying the vegetation features of different enclosure measures and soil physical and chemical properties,the paper analyzed the influences toward vegetation growth.The ANOVA analysis result indicated that,in the different enclosure measures,the soil compaction is the main factor which affects vegetation growth.And the further regression analysis indicated that correlation between the soil compaction and the ground biomass or the vegetation coverage was negative.While the soil compaction changed from 2.0~3.0 kg/m2,the ground biomass and the vegetation coverage are higher.
