Abstract
This paper presents an improvement guideline of irrigation reservoir as environmental resources. In order to classify reservoirs for improvement planning, five common factors were extracted from factor analysis of fourteen indicators. Through cluster analysis, reservoirs could be classified in five groups: big reservoirs, irrigation reservoirs for agricultural propose, rural reservoirs adjacent to residential area, small reservoirs in urban areas and small reservoirs in rural areas. Also, characteristics of reservoirs improved as urban parks and as rural improvement project were analyzed, and compared with those groups to see conditions for selection for improvement planning. The selection method shows that the improvement planning emphasizes the use of reservoir as irrigation facility or as environmental resources.
