冠岳樹木圓地域內 荒廢山地土壤의 肥沃化를 통한 綠化促進에 關한 硏究(II)

禹保命,權台鎬,李宗學,金景河,李峻雨,麻鎬燮 서울大學校 農科大學 1986 서울대농학연구지 Vol.11 No.2

The shallow soil depth and severe rock exposures on the hillslopes in the Kwanak aboretum area which resulted from the heavy soil erosion have made very poor growth of forest vegetation. In order to establish the forest vegetation in this area, it is urgent to recover the fertility of soil and the productivity of existing trees. For this reason, fertilization experiment (using the briquet compound fertilizer) was conducted on summer and autumn season in 1983 with the 4 main native species (Pinus densiflora, Pinus rigida, Juniperus rigida, Rhododendron schlippenbachii) growing on these eroded hillslopes. Result in 1985 and 1986 of this experiment represented that the fertilization was effective toward both height and root-collar diameter growth of trees and spring fertilization was, relatively, more effective than autumn fertilization. It also represented that effects of fertilization to P. rigida were more than those to other species. Therefore, besides the engineering methods and afforestation measures for soil erosion control, rapid establishment of vegetation through conservation and recovery of existing trees by fertilization is available measures for the rehabilitation of rockily eroded hillslopes like Mt. Kwanak area.

In this paper, given a simple polygon and a simple chain ch(??,??), the notion of chain visibility polygon of a simple polygon P is introduced, and a optimal algorithm for finding the chain visibility polygon in a simple polygon is presented. In the preprocessing step, the simple polygon is triangulated, and computed shortest paths from ?? and ?? to all other vertices in linear time. Then, Condensed dual tree composed of triangles of triangulation is traversed and visible areas from the chain is computed and merged in linear time.
