摘  要:
以毛乌素沙地东北部的油蒿群落为研究对象,对封育和未封育区的油蒿群落进行比较研究,结果表明:封育增加了群落的盖度,封育区群落盖度较未封育区提高了26%;封育区与未封育区油蒿群落生物量间存在显著差异,封育可以明显提高油蒿群落的生物量,但却降低了油蒿个体的生物量;土壤水分方差分析表明,封育区与未封育区土壤水分间差异不显著。

摘  要:
An experiment was conducted to study the vegetation coverage, biomass and soil moisture of Artemisia ordosica communities for year-round exclusion and non-exclusion in the northeastern of Maowusu sandy land. Result showed that vegetation coverage increases by adopting exclusion measures judging from the fact that the vegetation coverage of communities for year-round exclusion is 26 percent higher than that for non-exclusion. Exclusion can markedly increase community biomass in terms of the significant difference in community biomass between year-round exclusion and non-exclusion, while the individual biomass of A. ordoska shows a decreasing tendency. There is no significant difference in soil moisture between year-round exclusion and non-exclusion communities.
