中文摘要	通过对干旱区湿地-艾比湖湿地土壤有机质、碱解氮、速效磷、速效钾等土壤质量指标分析,结果表明:湖区土壤有机质含量呈现出盐化草甸土>盐土>灰棕漠土>风沙土的规律。湿地土壤有机质空间上表现为湖区以东、以西、以南方向上层土壤有机质依次递减,湖区以北上层土壤有机质先递减后递增。湖区以西中层土壤有机质与上层趋势一致,以北有机质含量较大,湖区以东、以南方向有机质含量较小。下层土壤样品中,湖区以西、以北位置均呈现递减趋势,以东方向有机质含量较高,以南较小。盐化草甸土有机质含量自上而下依次递减,趋势明显。盐土、风沙土、灰棕漠土有机质含量上层>中、下层,中下层含量差异较小。土壤中的碱解氮、速效磷、速效钾含量与土壤中有机质含量具有较好的相关性。
英文摘要	In this paper, soil organic matter, alkali - hydro nitrogen, available P, available K of Ebinur Lake wetland soil were selected as the determination indicators. The results of analysis of the indicators with statistical method and the Arcgis method showed that soil organic matter content is of evapo - salinization meadows soil > sandy soil>gray - brown desert soil>sandy soil. Spatial distribution rule of upper soil organic matter in Ebinur lake wetlands is that it is decreasing in the east, west, south of the lake, it is decreasing after increasing in the north of the lake. The trend of middle soil organic matter in Ebinur lake wetland is the same with the upper in the west, it is higher in the north and lower in the east and south of the lake. The trend of lower soil organic matter in Ebinur lake wetlands is decreasing in the west and north of the lake, the soil organic matter is higher in the east and lower in the south of the lake. The soil organic matter of the evapo - salinization meadows soil is decreasing, the trend is abvious. The upper soil organic matters of the sandy soil and gray - brown desert soil are higher than that in middle and lower layers of soils. The difference of the content is very little between middle and lower layers. There is a good correlation in the organic matter and the alkali - hydro nitrogen, available P and available K.
