项目摘要

Extensive comparison studies were carried out to evaluate the function of forest ecosystems to purify the environmental pollutant.1. Water chemicals of rain and runoff stream water from thirteen forested watersheds which are located in the area of Hokkaido, Gifu, Mt.Hiei in Kyoto, and Takamatsu in Japan, Southern China and Northern Thailand were analyzed.According to Warmth Index, those six areas are classified in cool-temperate, warm-temperate or sub-Tropical zones.Both in cool-temperate and sub-tropical areas, major dissolved ions in runoff water were low comparing with those in warm-temperate area.2. In Shimane prefecture, high concentration of Na^+, Cl^-, NO_3^-, SO_4^<2-> ions was detected in snowfall.However, the effects of these chemicals on runoff water were not detected.3. In Yamaguchi Prefecture, wet-and dry-fall to the forest was separately measured.So-called man-made pollutants were contained more in dry-fall.4. On the three kinds of forest soils in Chugoku area, the hydraulic conductivity was compared using heavy water and heavy nitrogen.5. Through the measurements of natural abundance of ^<15>N in rain and soil water, denitrification in the watersheds was confirmed.
对森林生态系统净化环境污染的功能进行了广泛的比较研究.本文分析了日本北海道、岐阜、京都比永山、高松、中国南方和泰国北方等13个森林流域的雨水和径流水化学特征。根据温暖指数,这6个地区被划分为冷温带、暖温带和亚温带。无论是在冷热带还是亚热带地区,与暖温带地区相比,径流水中主要溶解离子含量较低。岛根县降雪中检测到高浓度的Na^+、Cl^-、NO_3^-、SO_4^<2->-离子,但未检测到这些化学物质对径流的影响.在山口县,分别对森林的湿、干落叶进行了测定,干落叶中含有较多的所谓人为污染物。在中国地区的三种森林土壤上,采用重水重氮处理,比较了土壤导水率的差异.通过对<15>雨水和土壤水中^ N天然丰度的测定,证实了流域内存在反硝化作用。
