国外森林环境水化学研究综述

Research on Water Chemistry of Forestry Environment in Foreign Countries

国外从19世纪开始进行森林降水化学的研究,那时主要的研究目的是论证森林对降水中水化学物质的再分配、迁移扩散规律等。20世纪70年代后期,大气沉降和环境酸化对森林水质的影响成为研究趋势。森林环境水化学问题成为近20多年森林水质研究的重点。文章综述了森林地区环境水化学的主要几个研究方向,并将大气沉降(主要是湿沉降)、林地水环境作为主要综述的内容。

Since nineteenth century, chemistry of forest precipitation was studied in foreign countries. The main purpose was to demonstrate the law of forest to reallocation transfer and pervasion of precipitation chemistry substance at that time. Late 1970' , the research trend was to study the influence of air sedimentation and environment acidification to water quality of forest. The problem of forest water chemistry had become the focal point of forest water quality. The main several research aspects in forest water chemistry, specially air sedimentation ( mainly wet sedimentation) , and woodland water environment were summarized.
