阿其克苏河河岸带典型植被覆盖下土壤化学特征

Analysis on Soil Physical and Chemical Characteristics under Different Vegetation Coverage in the Riparian Zone of Aqikesu River

以阿其克苏河下游河岸带不同植被覆盖下的土壤为研究对象,选取土壤中养分、盐分指标进行测定,结果表明:阿其克苏河下游河岸带土壤呈碱性;有机质、水解氮、速效磷含量较低,同时呈现中等变异;不同土层的盐分含量差异显著,表层含盐量远高于其他土层,表聚现象明显.通过土壤中总盐与可溶性离子相关性分析表明,总盐含量与Cl-,HCO-3呈高度相关;Ca2+与Mg2+和SO2-4呈高度相关;Mg2+和HCO-3呈高度相关;SO2-4与K++Na+呈显著相关.

With Aqikesu River downstream of riparian zone under different vegetation soil as the research object,nutrients in the soil have been selected,and salt index been measured.The results show that Aqikesu River downstream riverbanks with alkaline soil;Hydrolysis of organic matter,nitrogen,available phosphorus content is low,and at the same time present the medium variation;Different significant difference has been found in the soil salt content.Surface soil salt content is much higher than other,table gathered phenomenon is obvious.Through the soil total salt and the correlation analysis show that the soluble ions total salt content and highly correlated to the Cl-,HCO-3;Ca2＋and Mg2＋and SO2-4in more highly relevant;Mg2＋and HCO-3are highly relevant;SO2-4and K＋＋ Na＋were significantly related.The research for the local ecological construction provides the scientific basis and rational utilization of resources.
