Investigation of aquatic environments, climate, economic and social conditions in River Ping and its catchment area of the northern Thailand -In order to propose environmental policy and promote environmental education

对泰国清迈市周边的平江、光河和美嘉运河的水质进行了调查。平江上游水质很好，但由于山体侵蚀的土壤和城市污水的流入，水质明显恶化。针对泰国清迈市周边的平江、广河和美嘉运河的水质状况，分析了泰国清迈市周边地区的营养盐、有机物和离子负荷对平江水质的影响。平江上游水质很好，但由于山体侵蚀的土壤和城市污水的流入，水质明显恶化。麦卡渠的营养盐、有机物和离子负荷对平江水质的影响，我们开展了该装置的研究，目的是提高RELA…光水库下游的农业用水效率更多的原因是与北方工业区的用水竞争。此外，由于兰普伦市是泰国政府重点批准制定地方21世纪议程的地区，因此调查了兰普伦市环境改善计划和成就的相对位置。在与生活文化的关系方面，我们走访了制造Pla Som和Pla La的民居和工厂，并调查了它们的分布与河流的关系。我们与当地专家一起研究了清迈生态旅游的理想方式。来自清迈大学的泰国科学家报告了日本清迈的水环境和环境教育，加深了对平江水环境的了解。我们在清迈举行的“2003年国际环境管理研讨会：政策、研究与教育”中，报告了历时三年的调查研究成果，结果表明，教师和当地居民的环境意识正在上升。此外，继续以制定学校周边环境教育实践方案为研究目标是非常重要的。我们想要深化这一调查研究。较少

Investigation of water qualities were carried out in Ping River, Kuang River and Mae Kha Canal in around Chiang Mai City in Thailand. The water quality of up-stream of Ping River is very good, but deteriorated remarkably by inflowing of soil with erosion in the mountain side and waste water from urban area. The loads of nutrients, organic compounds and ions from Mae Kha Canal affect on the water quality of Ping River.Investigation of water qualities were carried out in Ping River, Kuang River and Mae Kha Canal in around Chiang Mai City in Thailand. The water quality of up-stream of Ping River is very good, but deteriorated remarkably by inflowing of soil with erosion in the mountain side and waste water from urban area. The loads of nutrients, organic compounds and ions from Mae Kha Canal affect on the water quality of Ping River.We carried out the investigation of the device, aimed at the efficiency improvement of the agricultural water use in the downstream of Kuang reservoir in rela … More tion to the competition for the water use with the northern industrial estate. Moreover, as Lampurn city is a region where Thai government has emphatically granted for making the local agenda 21, a relative location of the environmental improvement plan and the achievement of Lampurn city was investigated. In the relation to the life culture, we visited the houses and the factories which made Pla Som and Pla La, and investigated the relation between their distribution and the river. We studied about the ideal way of eco-tourism in Chiang Mai with local experts. Thai scientists from Chiang Mai University reported about aquatic environment and environmental education of Chiang Mai in Japan, and we deepened understanding of the aquatic environment of Ping River. We reported the results achieved by the investigation research of three years in "2003 International Symposium on Environmental Management: Policy, Research and Education" held at Chiang Mai.As our results, it was able to be confirmed that environmental consideration of the teachers and the local residents was rising. In addition, it is very important to keep the research aiming at making the practice program of environmental education in around school. We want to deepen this investigation research. Less
