Abstract: Soil developed on basalt has its distinctive geochemical superiorities: the energy transforming rate (ETR) of its ecosystem could be 1.39—3.46 times higher than that of soils from other parent materials, and its structure and K-supplying are not so bad, being an important soil resource not been paid attention to for Jong time. But, for soils formed under different geochemical developmental stages, the difference of their ETR could be 77.86%.Among these soils, weakly ferrallitic one has greater potentiality for exploitation and utilization. The enrichment of Fe₂O₃ and its transformation characteristics in soil and the soil geochemical variations induced by various positions of geological stratums and various types of basalts give a significant influence on agro-ecological processes. Therefore, it is considered that geochemical study is an effective way for the studies of resource ecology.
