砂防施工法의 變遷에 關한 硏究(Ⅱ) : 砂防造林關係를 中心으로 Laying Stress on Erosion Control Reforestration = Study on the Changes in Erosion Control Works(Ⅱ)

다국어 초록 (Multilingual Abstract)

There have been many changes since the year 1907 when modernized erosion control works were executed for the first time in our nation.
The author published the thesis in the year 1983 regarding the changes in erosion control works and now made every effort for erosion control works to be executed effectively by using as the reference material the results of this study regarding the changes in erosion control reforestation
The results are as follows ;
1) From the year 1907 till 1986, the total area where the erosion controlworks had been executed amounted to 1,099,294 ha and the number of seedling planted amounted to 3,639, 738,000 seedling.
2) Considering the changes of greening works, strip terrace-sodding works and spot terrace-sodding works were executed till 1920 s. and additionally the direct seeding works from 1930 s Also the surface greening works were executed with the methods of spot seeding and strip seeding from 1950 s, and the direct seeding works with straw-mat mulching and the straw-net strip-sodding works have been executed as newly-developed works since 1970 s.
3) Despite many changes in policies and institutions relating to erosion control works, there hadn't been the standard guide of techniques yet. Accordingly, it is necessar to urgently establish the standard guide of erosion control techniques.
4) Effective surface greening works have to be developed.
5) The phenomenon in which useful needle-leaf trees were pressed must be restrained by erosion control planting having proper density.
6) The study on the early effective works for erosion-controlled forest is demanded.
