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河、光河和梅卡运河进行了水质调查。平江上游水质较好，但由于山腰侵蚀土壤和城区污水的流入，水质明显恶化。美喀运河的营养物、有机物和离子负荷对平河水质的影响。对泰国清迈市周边的平河、光河和梅卡运河进行了水质调查。平江上游水质较好，但由于山腰侵蚀土壤和城区污水的流入，水质明显恶化。美喀运河的营养物、有机物和离子负荷对平河水质的影响。为了提高库区下游农业用水效率，加强与北方工业用地的用水竞争，对该装置进行了研究。此外，由于兰埔市是泰国政府重点批准制定地方21世纪议程的地区，因此调查了环境改善计划与兰埔市成就的相对位置。在生活文化的关系上，我们参观了普拉索姆和普拉拉的房屋和工厂，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理想的清迈生态旅游方式。来自泰国清迈大学的科学家在日本对清迈的水环境和环境教育进行了报道，加深了我们对平河水环境的了解。我们在清迈召开的“2003年国际环境管理：政策、研究和教育研讨会”上报告了三年的调查研究成果。根据我们的研究结果，可以证实教师和当地居民对环境的考虑正在增加。此外，为制定环境教育在周边学校的实践方案而进行研究是十分重要的。我们要进一步深化这一调查研究。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
