Abstract

以鄂尔多斯市准格尔旗永利露天煤矿排土场不同植被类型(苜蓿、沙打旺、沙打旺+油松)土壤为研究对象,以
复垦1a土壤为对照( CK ),探讨了永利煤矿排土场不同植被类型条件下土壤理化性质和酶活性变化特征,以及两者
之间的相关关系,为该区露天煤矿排土场的植被恢复工作提供理论依据。结果表明:矿区复垦对土壤质量有一定的
改善,表现为沙打旺 > 苜蓿 > 沙打旺+油松 >CK ,土壤酶活也得到了一定改善。 0 — 10cm 土层,沙打旺的有机碳为
5.18g / kg ,显著高于其他植被恢复措施,沙打旺对于改良土壤有一定的优势;土壤有机碳、全氮、酶活性随着土层深度
的加深而降低,土壤酶活性与土壤养分之间存在不同程度的相关性,土壤磷酸酶、蔗糖酶与土壤容重呈显著正相关关
系;不同植被类型间土壤酶活性亦存在显著差异,土壤蔗糖酶表现为沙打旺 > 苜蓿 > 沙打旺+油松 >CK ,沙打旺脲酶
显著高于其他植被类型及 CK 。

Other Abstract

: In order to understand the effects on soil physical and chemical properties and enzyme activity varia -
tion in different vegetation types , three kinds of vegetation types ( Medicago sativa , Astragalus adsurgens
Pall , Astragalus adsurgens Pall+ Pinus tabulaeformis Carr ) were selected as research samples in Jungar
Banner , Erdos.The studies were help understand the relationships between vegetation restoration and soil
quality.The results showed that soil physical and chemical properties of different vegetation types had been
improved , were characterized by Astragalus adsurgens Pall> Medicago sativa > Astragalus adsurgens Pall
+ Pinus tabulaeformis Car>CK ; the soil organic carbon in 0 — 10cm layer in Astragalus adsurgens Pall
community was 5.18g

kg
, which was significant higher than other vegetation types ; soil organic matter , to

tal nitrogen and enzyme activities under different vegetation types declined with increase of soil depths.
There were significant correlations between soil enzyme activities and soil nutrients.Phosphatase and invert -
ase were significantly positively correlated with soil bulk density , suggesting
that soil bulk density had sig -
nificant effects on soil enzyme activities.Soil enzyme activities also significantly differed from different vege -
tation types , with respect to invertase , Astragalus adsurgens Pall> Medicago sativa > Astragalus adsur -
gens Pall+ Pinus
tabulaeformis Car> CK.The invertase of Astragalus adsurgens Pall was twice higher  than Astragalus 
adsurgens Pall+ Pinus tabulaeformis Car , and urease in Astragalus adsurgens Pall soil
was significantly higher than other vegetation types.
