Abstract
This paper is a research report concerning the water and soil maintenance and the technical advance of disaster preventing function of forests. As for the water maintenance control to clarify the water maintenance function of forests and to advance retaining and increasing technique, amount of precipitation on valleys and ridges, amount of evapotranspiration in a summer rainy season, underground water in woodlands and water circulating characteristics in montane zones were studied. The amount of evapotranspiration and the crown interception in water drainage area in Tsukuba forest of Japan were surveyed. A formula to estimate the flow rate was derived by surveying the change of flow rate through cutting forests at a riverhead in a heavy snow area and by analyzing data at 29 drainage areas. As for the clarification of the occurring mechanism of a soil disaster and the development of forest conservation technique, a simulation of boulder flow flood at a practical damaged district was carried out and it could be estimated by a tank model that the water level at a collector well fallen down in a landslide area. As for the survey of disaster preventing function of forests and the improvement of disaster preventing means, if damaged

As for the survey of disaster preventing function of forests and the improvement of disaster preventing means, if damaged trees in frozen damage and discoloration area are pruned, the discoloration becomes very slight. The arborescent trees were selected from the standing tree density or forest physiognomy for the frequent land of full-depth avalanche. Japanese beeches, maples, oaks and Magnolia hypoleuca are suitable for a heavy snowarea. 1 tab.}
