【摘要】 目的　利用地壳元素分布特征与动植物体内微量元素含量间的关系,指导生态环境综合治理。方法　借助已有的基础地球化学资料,揭示岩石、土壤中微量元素地球化学特征与经济作物、地方病之间的关系,寻求内在规律,圈定关系区、建立相关数据库信息系统。结果　中国地方病的分布与基岩出露程度、地表剥蚀程度、森林发育状况、相关元素的运移富集等因素密切相关;特色经济作物与岩石、土壤中微量元素的含量具有正相关关系。结论　利用动植物体内微量元素含量与地壳元素分布特征间的关系及其相关信息库,可指导经济作物的开发、预防地方病的发生,促进生态环境的综合治理与经济可持续发展。更多还原

【Abstract】 AimUtilizing the relativity between the feature of the element distribution in crust and the micro-element content in flora and fauna, directions for comprehensive harnessing of ecological environment is given.MethodsReveal the relations between the economic plants,endemic disease and geochemical field of rock and soil micro-element with the aid of existing geochemical data,and seek the internal relations and regularity,establish incidence zone and the information system of correlation data base.ResultsThe distribution of endemics relate closely to the naked degrees and enudation degrees of basement rock,the growth degrees of forest cover and the enrichment degrees of the correlative elements;the economic plants with the local features relate closely to the micronutrients in rock and soil.ConclusionUtilizing the information system,it is possible to guide the development of the economic plants,prevent the endemic disease,ensure sustainable development of economy and comprehensive harnessing of ecological environment.更多还原
