説明

The problem in industrial water use has been seriously in Japan, especially about the Pacific Belt industrial advanced areas. But concerning inner areas, there are a few reports about lndusrial water. So, the aim of this paper is to analyse the regional characteristics of industrial water in Tochigi prefecture. The results of this study are summarized as follows; 1. Tochigi prefecture is characterized as the typical type of using enough circulating industrial water and abundant groundwater. But, there are few official industrial water supply systems. 2. It shows a geomorphological character in Kinu-nver and Waterase-river drainage basin where on the upper-stream region it indicates river water use type, on the other hand on the middle-stream and down-stream region it indicates groundwater use type. But, in Naka-river drainage basin, it shows almost groundwater use type everywhere. 3. The regional difference of industrial water supply reflects the industrial structure of each city, town and village, two factors influence the regional character. First is the existence of water-oriented industry, for example pulp factory and chemical group factories. Second is the existence of the special large factory such mechanical industry as automobile factory. 4. After the construction of Kawazi-Dam, the official big industrial water supply conduit (Kinugawa Sagandaichi-chiku Kogyoyosuido Jigyo) is under construction now. So, the character of industrial water supply in Tochigi prefecture will change in future.
