堆石地斜面의 綠化方法과 綠化用 適合樹種 開發에 關한 硏究 = A Study on the Development of the Reclamation Method and Suitable Species for Afforestation on Stone Armoring Tips

다국어 초록 (Multilingual Abstract)

The purpose of this study is to develop the reclamation method and suitable species for afforestation on various kinds of stone armoring tips such as mining waste tips, ripped stone tips and weathered debris tips. 10 stone armoring tips and 30 species were estimated. The results of the study are summarized as follows;
1. In common characteristics of stone armoring tips, size of stones and void became larger and soil content became less with an increase in the deposition depth.
2. The most suitable reclamation technique is the pocket planting techique after foundation works like stone terracing.
3. It is necessary to use high water-retaining soil in earth and add organic matters to it. The suitable volume of soil must be determined by characteristics of tips and species planted. And it is essential, in order to retain and accelarate the effect of the earth, to apply the soil fixing treatment with anticorrosive materials.
4. In planting composition, it is available to make the ratio of evergreen trees to shrubs by 1:1 and plant evergreen prostrate shrubs or climbers to 50 percent within shrubs, and alter the order of planting of the same lifeformed species at each terrace.
5. The effective planting method is to plant three sapling or more per pocket in a group.
6. Within estimated species, the more suitable species for afforestation on stone armoring tips are 13 species, and 12 species are also considered good for the same purpose. Especially, 20 species unused before are developed as new plant materials for the environmental conservation.
