云南小江流域不同土地利用类型土壤微量元素的对比分析
|
摘要
文章对云南小江流域不同土地利用类型(耕地、林地、园地、建设用地、裸地)土壤的微量元素进行空间插值、方差分析和相关性研究,旨在探讨云南小江流域不同土地利用类型微量元素的分布和迁移规律。结果表明:除Mo的含量较低外,小江流域土壤中Cu、Mn、Ni和Zn的含量普遍较高。各微量元素含量在不同土地利用类型中具有明显的差异性,园地土壤微量元素含量最高。微量元素的变异程度均属于中等变异。Cu、Mn、Mo、Ni、Zn的空间分布具有一定的相似性,高值区主要集中在海拔较低的岩溶河谷区右侧和盆底沉积平坝区,主要土壤类型为碳酸盐岩红壤;低值区集中在海拔较高的河谷区左侧和中山区,主要土壤类型为碎屑岩。地貌、土壤母岩和人为活动是影响微量元素分布和迁移的重要因素。
In this paper,the spatial interpolation,variance analysis and correlation analysis of trace elements in different land use types(cultivated land,woodland,garden land,construction land,bare land)in Xiaojiang river basin of Yunnan Province are studied,and the distribution and migration of trace elements in different land use types are discussed.The results showed that:(1)the contents of Cu,Mn,Ni and Zn in the soil of Xiaojiang river basin were generally high,except for the low content of Mo.(2)The contents of five soil trace elements in different land use types had obvious differences,of which the content of trace elements in garden land was the highest;(3)The degree of variation is moderately variable in all five trace elements.(4)The spatial distributions of Cu,Mn,Mo,Ni,and Zn have certain similarities.The high value areas were mainly concentrated in the right side of karst valley area with lower elevation and the pelvic floor sedimentary dam,where the main soil type is carbonate red soil;while the low value areas were concentrated in the left side of karst valley area with higher elevation,and high mountain karst areas,where the main soil type is clastic rock..In all,landscapes,soil parent rock and human activities are important factors affecting the distribution and migration of soil trace elements in the study area.
