Environmental education program of a water evaluation index and closing water area clarification.

虽然水质环境教育自古以来就有，但目前还没有准确的水质污染指标。环境教育的障碍是一个类似于技术争论的问题。本研究通过对灌溉塘等封闭水域进行水化学分析，并进行多变量分析和神经网络分析，得到准确、简单的水指标。制定环境教育方案，进行教育实践和教师培训。作为基础研究，对大阪府内25个池塘进行了化学、物理、生物调查，并对调查结果进行了自组织图和模糊聚类分析。采用“模糊c-均值法”对荷花等新兴植物的水净化效果进行了测试分析。从两个实验结果来看，氮和磷是较好的水分评价指标，出苗植物有助于澄清水分。作为一项教育实践，高中学生和教师使用水质评价指标对大阪府的河流水质进行了调查，并由教师给学生分析结果。通过对教师的培训，制作了《水环境教育实践范例》和《水分析流程图》，说明了环境教育方案与水质澄清、水质评价等的科学意义。作为教育中心和学校的环境教育宣传材料。这一研究结果已在各学术团体公布，并编制成380页的A4版报告。

Though the environmental education of the water quality has been done from the old days, there is no index of the precise water pollution. The obstacle of the environmental education is a problem like a technological argument.In this research, to get an accurate and simple water index, water chemical analysis of the closing water area such as irrigation pond was done, and multivariate analysis and neural network analysis were done. Environment educational program was developed, and then education practice and teacher training were done.As a basic research, 25 pond was chemical, physical, biological surveyed inside Osaka Prefecture, and the result was analyzed the self-organization map and the fuzzy clustering. Artificial closing pond was made, and water purification by the emerging plant such as a lotus was tested and analyzed by "fuzzy c-means method". From two results of an experiment, nitrogen and phosphorus were excellent water evaluation index, and emerged plants contribute the water clarification.As an education practice, high school students and teachers survey the river waters in Osaka Prefecture used a water evaluation index, and teacher gave the class to analyze a result.As a training of teachers, "Example of practicing the environmental education of water" and "Water analyses flow chart" is made, and explanation scientific meaning of environmental education program and water clarification, evaluation of water quality etc. It used as material of environmental education promotion in the education center and the school.This result of the research was announced at various academic societies, and work up the A4 edition 380-page report.
