江西省阳储岭富钼景观中钼的生物地球化学特性研究

Research on the biogeochemical characteristics of rich Mo landscape of Yang chuling,Jiangxi

在阳储岭钨钼矿体为中心的次生分散晕上，形成了富 Mo地球化学环境。这一决定因素使该区发生和演化成独特的生物地球化群落。这个群落以亲 Mo为共同性，但由于植物种亲 Mo程度的差别性，区别出高极限、中极限和低极限三个植物类型。其中高级限豆科植物种绿叶胡枝子最具高亲 Mo个性，因此可以作该环境的指示植物。富 Mo地球化学环境与亲 Mo植物群落的一致性使两者之间达到自然生态平衡。但因此打破了社会生态平衡，致使本区人畜多患富 Mo地方性功能症。如何充分利用富 Mo生物地球化学环境的有利条件，克服其不利因素应该成为一个值得重视的问题。

Rich Mo geochemical environment is formed in the secordary dispersed phase around Yangchuling W and Mo deposit center.The area has evolved into a particular biogeo- chemical colony due to this decisive factor. the colong has parent Mo as its generality.yet due to the different degrees of the relationship between plants and Mo,there are high－ limit,medium－ limit and low－ limit plants.Of the leguminous,lespcdeza buergeri has high pareut Mo character.So it can serve as the indicator plant of the environment.The consistency between rich Mo geochemical environment and parent Mo plant colong has made them reach a natural ecobalance.At the same time it has damaged the social ecobalance it has caused the local people and livestock to have rich Mo functional diseases.it should be taken seriously that we should make good use of the advantages of rich Mo geobiological environment and overcome the unfavorable factors.
