中文摘要	为探讨新疆石灰性土壤锌的组分分布特征及锌有效性的影响因素,对南北疆3种最主要土壤类型农田土壤锌及其组分含量进行研究。结果表明:新疆石灰性土壤有效锌平均含量为潮土(0.69 mg/kg) >棕漠土(0.57mg/kg) >灰漠土(0.51 mg/kg), 变异系数为灰漠土>潮土>棕漠土。在土壤锌组分中,松结有机态锌(WBO) 、碳酸盐结合态锌(CARB) 、氧化锰结合态锌(OxMn) 、紧结有机态锌(SBO) 、无定形铁结合态锌(AOFe)平均含量均为潮土>棕壤土>灰漠土。南北疆土壤锌背景值不同,南疆土壤全锌含量高于北疆土壤,而北疆土壤全锌变异较大。土壤碳酸钙含量和物理性粘粒含量与松结有机态、碳酸盐结合态、紧结有机态锌分配率高度相关。松结有机态锌、碳酸盐结合态锌及松结有机态锌分配率与土壤物理性粘粒含量呈(极)显著正相关。交换态锌与松结有机态锌呈显著正相关。松结有机态锌与碳酸盐结合态锌呈显著正相关。石灰性土壤有效锌含量与松结有机态锌、碳酸盐结合态锌含量呈显著正相关,可用方程y=0.306+0.123WBO+0.116CARB(F=20.095, r~2 =0.801**)预测。
英文摘要	This paper studied Zn contents and its fractal components by 3 typical types of soils in southern and northern in Xinjiang. The results showed: The average available Zn was aquic soil(0.69 mg/kg) >brown desert soil(0.57 mg/kg) >grey desert soil(0.51 mg/kg), the coefficient of variation was grey desert soil> aquic soil >brown desert soil. In the Zn fractal content, the components contents of SBO, CARB, OxMn, WBO and AOFe were aquic soil > brown desert soil>grey desert soil. The background value of soil Zn were different, total zinc content of southern soils was higher than that of northern soils, which were more variability. The contents of CaC03 and physical clay were highly relevant to the percentages of WBO, CARB and SBO. The relative percentages were significantly or very significantly positive in physical clay content and WBO, CARB, SBO. The content of WBO remarkably influenced the content of Exc. There was significant positive correlation between WBO and CARB. The content of available Zn was remarkably influenced by WBO, CARB, which could be forecasted by the equation: Y=0.306+0.123WBO+0.116CARB(F=20.095, r2 =0.801**).
