项目摘要

Benefit of water environmental improvement of Lake Suwa was evaluated to be 730 million Yen per year by Contingent Valuation Method. On the other hand, the damage of secondary environmental loads, such as CO2 generated was 23 million Yen. This comparison justifies the water improvement of this lake. Choice experiments showed that people give low value to protection of wildlife, and the water environmental improvement was esteemed be higher than mortal risk reduction. The analysis or human activities showed that the nitrogen load to Lake Suwa was reduced by half in the past 30 years. Frequent survey of water quality revealed that non-point source like the cropland generates high loading with rainfall. This shows that prevention of soil erosion is effective method to reduce nutrient loading to this lake. The correlation between concentration of PAHs in roadside and amount of traffic was analyzed. The risk of chemical substances in the ecosystem and drinking water in Hiroshima Bay was evaluated. The relation between the amount of loading from the basin, and the amount of deposition in the lake was analyzed for poly aromatic hydrocarbon and butyl tin. These two were comparatively well in agreement. In Lake Suwa, outbreak of algal bloom decreased in recent years and the amount of existing of mosquito fell remarkably. Moreover, it turns out that reduction of a fish catch is being enhanced with a peak of the 1970s which were the severest as for contamination. Although water quality improvement progressed by construction of a sewer in Lake Suwa, the percentage of contribution of the load from non-point source increased.
采用条件估值法,估算出苏哇湖水环境改善的年效益为7.3亿日元。另一方面,产生的二氧化碳等二次环境负荷造成的损失为2300万日元。这种比较证明了这个湖的水质改善是合理的。选择实验表明,人们对野生动物保护的重视程度较低,认为水环境的改善高于降低人类的风险。分析或人类活动表明,在过去的30年里,苏瓦湖的氮负荷减少了一半。频繁的水质调查显示,农田等非点源产生的降雨量很大。由此可见,防止水土流失是减少该湖营养盐负荷的有效方法。分析了路侧多环芳烃浓度与交通量的相关性。对广岛湾生态系统和饮用水中化学物质的风险进行了评估。分析了多环芳烃和丁基锡的盆地负荷量与湖内沉降量的关系。这两个人的意见比较一致。近年来,苏瓦湖赤潮暴发有所减少,蚊虫存活量显著下降。此外,事实证明,渔获量的减少正在加强,20世纪70年代的高峰是污染最严重的时期。虽然在苏瓦湖建造一条下水道改善了水质,但非点源负荷所占的百分比有所增加。
