| 摘 要： | 通过对新疆艾比湖湿地自然保护区内土壤颗粒组成、水分、盐分、pH值和速效养分(氮、磷、钾)、有机质含量等土壤理化性状的空间分宜进行了探讨。结果表明:土壤颗粒组成主要以粉粒与砂粒为主,土壤质地以粉砂质壤土与砂质壤土为主;土壤含水量总体呈现湖周湿地>河流入湖口>泉眼分布区>荒漠的规律;艾比湖湿地不同类型土壤盐分存在明显的表聚现象,土壤盐化、碱化严重;艾比湖湖周土壤pH值北部高于南部,东部高于西部;艾比湖东部土壤速效氮含量最低,南部速效钾含量最低,北部速效磷含量最低,与此同时,艾比湖湿地速效养分在不同土壤类型不同剖面中的含量具有一致性;土壤有机质与碱解N含量相关性较强,其空间分布的特点是环湖土壤有机质含量低于阿其克苏河沿岸土壤有机质含量,梭梭荒漠表层及平均有机质含量与土壤含水量呈弱线性相关。

| Abstract: | The results show that the soil texture of most samples are composed of silt and grit.The law of soil moisture content in the study area is that wetland around the lake >the river-lake inlet>mouth of spring along the Aqiksu river>desert.Soil salt is gathered in the surface of the soil.Solonchak and salinized soil develop around Ebinur lake and along the Aqiksu river.The pH value in north of the study area is higher than south,east higher than west.Quick-acting nitrogen content is the lowest in eastern of Ebi... |
