摘要
米仓山地区是“长防工程”建设重点区域之一。本文从土壤水热性状、营养特点和肥力功能物质组成等研究评价了其垂直地带性土壤的肥力特征。指出本区分布较高海拔的黄棕壤等保持了某些良好的肥力特征,而分布海拔较低的黄壤等则在结构、土体构型、营养性及肥力功能物质品质等出现某些不良征兆,认为是退化结果。提出了调整树种结构、测土施肥、建立米仓山土壤资源保护区等措施。
The Micang Mountain area is one of the top-priority construction areas of the Long-range Protection Engineering Projects. Starting from soil water and thermal behaviors, soil nutrient properties and functional materials of soil fertility, etc. this paper studies and evaluates soil fertility features of vertical zonification; and points out that the Yellow Brown soil distributed at a higher altitude keeps better fertility while the Yellow Loamy soil spread at a low altitude appears to have some poor symbols in structures, soil body configuration, nutrient perporties and qualities of functional materials of soil fertility. This is regarded as the results of soil degradation. Also, this paper suggests some measures to be adopted including readjustment of tree species structures, fertilization in accordance with soil surveys, and establishment of protection area of soil rlsources in the Micang Mountain areas.
