摘要
紫色土是武夷山低丘土壤中的重要土壤类型,发育深受母岩的影响。通过典型采样和室内理化分析,收集野外实地考察的资料和室内实验分析的数据,对武夷山紫色土成土过程以及10项理化指标(pH、有机质含量、机械组成等)进行分析,得出母岩是紫色土发育过程中的决定性因素。针对目前紫色土存在的如地表破碎化、土壤薄层化等问题,提出了若干有效的治理措施。
The Purple soil is an important soil type on hills of Wuyi Mountain,its development deeply depend on geological element and parent rock. Typical samples of Purple soil were taken and used for physic-chemical analysis. Through collecting autoptical information of field and experimental data in lab,analyzed the Purple soil as well as the ten chemical index （pH,the content of soil organic matter,the soil texture, etc）. Reaching the results that parent rock was the deciding factor of the forming of the Purple soil. Aiming at the problems the fragmentation in the earth＇s surface and lamina in the soil etc for example,some effective measures were put forward.
