| 摘 要： | 在山地迎风坡最大降水高度以下区域,土壤物质的淋溶性具有随高度的降低而逐渐减小的高度分布规律.然而,对沙河-线7个土壤剖面土壤样品的分析结果表明,在秦岭-黄淮平原交界带内,土壤物质的淋溶性具有随着高度的降低而增大的反常现象,我们称之为土壤物质强淋溶效应.与两侧的山地和平原地区相比,在秦岭-黄淮平原交界带海拔高度150～300m之间的区域内,表层土壤的硅铝铁率陡然减小,土壤碱金属和碱土金属氧化物的淋溶率显著增大,硅、钛、锰、磷氧化物的积累率明显增大.此处出现土壤物质强淋溶效应的主要原因是山前"暖坡效应"的存在.较高的气温增大了当地土壤物质的活动性,为其淋溶提供了有利的环境地球化学条件.

| Abstract: | In the windward slope of mountainous below the biggest precipitation,the height distributional law of soil material leaching is that the soil material leaching goes from strength to weakness along with the height reduces.However,in the transitional region of Qinling mountains and Huang-Huai plain,the soil material leaching goes from weakness to strength along with the height reduces,and the unusal phenomenon is confirmed by the soil samples analysis results,which was collected from 7 soil profiles along the... |
