与元素丰缺有关的水文地球化学生态环境模型

The Ecological Environment Hydrogeochemical Model Related to Elements’ Richness or Deficiency

通过对离柳地区元素丰缺与生物和人群健康关系的地方病分布特征的分析 ,再结合其他地区的水文地质蓄水构造和不同水文地球化学作用、元素形成、迁移、分异特征 ,及与人群健康和生物的某些生态环境问题 ,耦合成为水文地质蓄水构造 -水文地球化学 -生态环境多重耦合模型 ;依据生态位理论将水文地质蓄水构造区内划分为三种不同的生态环境区 ,并作了分析和描述。将水资源与生态环境形成一个整体研究系统 ,为不同生态环境区水资源的合理开发利用 ,以及生态环境的控制。

By analyzing the distribution of ecological environment in Liliu distrit, in which the richness or deficiency of elements are related closely to living beings and human beings. Combining with the different hydrogeochemistry action and elements’ formation, migration and differentiation, and human beings’ health and some of the ecology-environmental problem of biont in hydrogeologic impounded structure zone, we give a multi-coupled model of hydrogeological hydrogeologic impounded structure, hydrogeochemistry and ecological environment. According to the Niche theory, we divide hydrogeologic impounded structure as three different ecological environment zone, and give carefully analysis and explanation. In the paper, water resources and ecological environment are looked as an integrated research system, the direction that water resources rational exploit and utilization in deferent ecological environment zone is given, the research of ecological environment controlling and transforming.
