摘    要:区城生态地球化学评价是在多目标地球化学调查基础上开展的一项区域评价研究工作,其目的是为国家和所薪究地区的国民经济建设、工农业结构调整和社会可持续发展提供基础地球化学资料。区域生态地球化学评价以异常元素的来源-成因-迁移转化-生态效应-预测预警为研究主线,以生态系统为研究基本单元,查明异常元素分布、分配、成因及来源,研究它们在地球表层备大层圈中的迁移转化规律,评价它们所产生的生态效应,应用地球化学和生态学的基本原理和方法对污染的生态系统进行预测预警,井提出治理建议,为国家区域性经济战略调整和工农业可持续发展提供科学依据。

关 键 词:区域生态地球化学评价  异常元素  预测预警

Abstract:The regional ecological geochemical assessment is a regional assessment carried out on the basis of multi-target regional geochemical survey, whose purpose is to supply basic geochemical data for the national economic construction, adjustment of industrial and agricultural structures and sustainable social development. It uses source-origin-remobilization-ecological effect-forecasting and early warning of anomalous elements as the main line of research and the ecosystem as the basic unit of research. Through it, we may ascertains the distribution, allocation, origin and source of anomalous elements, investigate their remobilization characteristics in various layers of Earth's surface, assess ecological effects that they have cause, apply the basic geochemical and ecological principles and approaches in the forecasting and early-warning of the polluted ecosystem, and put forward a proposal for their control so as to provide a scientific basis for the strategic adjustment of regional economy and sustainable industrial and agricultural development in our country.
Keywords:regional ecological geochemical assessment  anomalous elements  early warning
