中文摘要以9种沙生植被为研究对象,沙裸地为对照,采用野外调查与室内分析相结合的方法,分析不同沙生植被土壤易氧化有机碳(Coc)各组分的变化特征,并在此基础上提出土壤有机碳活性系数和敏感指数,探讨不同沙生植被对改善土壤质量的影响。结果表明:沙裸地种植植被后,Coc各组分和总有机碳(Ctoc)含量显著增加,但Coc各组分占Ctoc的比例无明显变化;与其他沙生植被相比,刺槐林(Robinia pseudoacacia)、花棒(Hedysarum scoparium)、臭柏(Sabina vulgaris)和樟子松(Pinus sylvestris var.mongolica)对改善土壤质量,提高土壤有机碳活性的作用更加显著。敏感指数表明Coc中第1部分(Cfrac1)和第2部分(Cfrac2)活性较强,其中Cfrac1对土壤质量变化更加敏感,可以作为衡量土壤质量状况的良好指标。相关性分析表明Cfrac1,Cfrac2,Cfrac3,Cfrac4,Coc与Ctoc之间极显著相关(P<0.01),与碱解氮和全氮成显著或极显著正相关(P<0.05或P<0.01),与全磷和速效磷之间的相关
英文摘要Abstract:The variation and fractions of oxidizable organic carbon(Coc)from nine psammophytes were studied
 through field investigation and laboratory analysis.Soil sensitive index and the influence of different
vegetations on soil quality improvement were also discussed.Results showed that the contents of Cocand
total organic carbon(Ctoc)increased significantly by planting on bare sand,whereas the percentage of Coc
to Ctochad no change.Robinia pseudoacacia (RP),Hedysarum scoparium (HS),Sabina vulgaris (SV)
and Pinus sylvestris var.mongolica (PS)improved soil quality and carbon activity more significantly compared
 with other vegetations.Sensitive index showed that the first(Cfrac1)and second fraction(Cfrac2)of Coc
had high activity,Cfrac1was more labile than Cfrac2and can be used to evaluate soil quality.Correlation analysis
 showed that there was a significant relationship among Cfrac1,Cfrac2,Cfrac3,Cfrac4,Cocand Ctoc(P<
0.01),and they were positively correlated with available N and total N (P<0.05),but not correlated
with total P and available P.Additionally,Cfrac4and Ctocwere positively correlated with available P(P<
0.01).There was a negative correlation between Cfrac1,Cfrac2,Cfrac4,Coc,Ctocand pH value(P<0.01or
P<0.05).In conclusion,Cfrac1can be used as a favorable indicator for soil quality evaluation.Robinia
pseudoacacia (RP),Hedysarum scoparium (HS),Sabina vulgaris (SV),and Pinus sylvestris var.mongolica
(PS)can be considered as preferential choice for soil quality restoration in Muus sandland.
