 note = {In a series of reports the authors are striving to achieve some standard patterns to evaluate the effectiveness of soil conservation practices on the denuded valley, in a way of analysing the successful recovery works of disastrous landslides occured in a small tributary stream of TENRYU RIVER. As the first step of it, they examined in this report, how far the soil could be recovered by effective works on the denuded valley in these twenty years and more after the starting. The examination was done by some comparative studies between two stages: 1) the present and 2) immediately after the disaster, on the transition of soil fertility and of forest flora. Expressed in details, comparisons were carried on 1) profile of soil 2) physical properties (gravity, density, moisture content, degree of saturation, air-void ratio etc.), 3) transition of forest flora and 4) stem analysis on the plots. The study will be continued in the next report about output of sand eroded and about effect of flood control due to soil conservation practices., Article, 信州大学農学部演習林報告 15: 65-84(1978)},
