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-,HCO3-呈高度相关;Ca2+与Mg2+和SO2-4呈高度相关;Mg2+和HCO3-呈高度相关;SO2-4与K++Na+呈显著相关。
以阿其剋囌河下遊河岸帶不同植被覆蓋下的土壤為研究對象,選取土壤中養分、鹽分指標進行測定,結果錶明:阿其剋囌河下遊河岸帶土壤呈堿性;有機質、水解氮、速效燐含量較低,同時呈現中等變異;不同土層的鹽分含量差異顯著,錶層含鹽量遠高于其他土層,錶聚現象明顯。通過土壤中總鹽與可溶性離子相關性分析錶明,總鹽含量與Cl-,HCO3-呈高度相關;Ca2+與Mg2+和SO2-4呈高度相關;Mg2+和HCO3-呈高度相關;SO2-4與K++Na+呈顯著相關。

With Aqikesu River dow nstream 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 differ‐ence has been found in the soil salt content .Surface soil salt content is much higher than other ,table gath‐ered 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 - ,HCO3- ;Ca2+ and Mg2+ and SO2 -4 in more highly relevant ;Mg2+ and HCO3- are highly relevant ;SO2 -4 and K+ + Na+ were significantly related .The re‐search for the local ecological construction provides the scientific basis and rational utilization of resources .
