中文摘要	【目的】对克拉玛依荒漠区新建的新疆杨、俄罗斯杨、榆树白腊混交林及外围原有的荒漠风沙土的土壤有机碳含量和生物量进行对比研究,旨在明确荒漠区植树造林对土壤有机碳含量的影响,为土地利用和生态保护提供基础数据。【方法】新建林区与外围原有的荒漠风沙土壤取样分析,对比研究荒漠区新建林和外围原有荒漠土壤总有机碳、活性有机碳、溶解性有机碳、微生物生物量碳含量以及生物量。【结果】新疆杨土、俄罗斯杨土、榆树白腊混交林土及荒漠风沙土0~50 cm土层总有机碳含量分别为10.38、6.73、11.16和4.37 g/kg;试验地0~50 cm土层土壤溶解性有机碳含量平均值的大小顺序为荒漠风沙土>榆树白腊混交林土>俄罗斯杨土>新疆杨土;3种林土与荒漠风沙土的活性有机碳之间有显著性差异,但林种土壤之间活性有机碳没有显著差异;林区土层微生物生物量碳含量均高于荒漠区,各土层俄罗斯杨土壤微生物生物量碳含量均小于新疆杨和混交林区。【结论】林区新建后的各层土壤有机质、活性有机碳以及微生物生物量碳含量增加,大小顺序为榆树白腊混交林土>新疆杨土>俄罗斯杨土>荒漠风沙土,溶解性有机碳降低。新建林区乔木和草本的生物量均大于荒漠风沙土的生物量。生物量大小顺序为总生物量大小及顺序为:俄罗斯杨>新疆杨>榆树白腊混交林>荒漠风沙土。
英文摘要	[Objective] The organic carbon contents in Karamy desert soil and the soil of newly planted trees,as Populus Alba L.,Populus.Russkii L.,Ulmus pumila & Fraxinus chinensis Roxb were analyzed to confirm the effects of planting trees on soil organic carbon and to provide basic data for land use and ecological protection.[Method] The total organic carbon (TOC),dissolved organic carbon (DOC),active organic carbon (AOC),microbial organic carbon (MBC)and Biomass of the soil samples were analyzed.[Result] The TOC contents of Populus Alba L.soil,Populus.Russkii L.soil,Ulmus pumila & Fraxinus chinensis Roxb soil and desert soil in the layer of 0 - 50 cm were 10.38 g/kg,6.73 g/kg,11.16 g/kg,4.37 g/kg,respectively; The order of DOC content in the soil in the layer of 0 - 50 cm is desert soil >Ulmus pumila & Fraxinus chinensis Roxb soil >Populus.Russkii L.soil >Populus Alba L.soil; The order of AOC content of the soil is:Ulmus pumila & Fraxinus chinensis Roxb soil >Populus Russkii L.soil >Populus Alba L.soil >aeolian sandy desert soil; There is significant difference between the AOC contents of the desert and the three forest soils,but there is no significant difference among the three forest soil samples.The MBC contents of forest soil were higher than that of the desert soil,and the MBC contents of Populus.Russkii L.soil were lower than the other two forest soil.[Conclusion]The TOC,MBC,AOC contents of soil increased after the desert was changed into forest,but the DOC content decreased.The changing order of TOC,MBC,AOC was Ulmus pumila & Fraxinus chinensis Roxb soil >Populus Alba L.soil >Populus.Russkii L.soil >desert soil; the biomass of herbage and arbor forest was higher than that of the desert.The biomass order of the three forests were Populus.Russkii L.>Populus Alba L.>Ulmus pumila & Fraxinus chinensis Roxb >desert soil
