  • 이 연구에서는 지난 3년간 북경임업대학교와 공동연구과제로 중국의 사막화방지 및 방사기술개발을 위한 연구의 일환으로, 특히 중국의 사구고정 및 방사공법을 조사 분석 평가하고자 수행하였다. 사구의 주요 형태에는 관목총사구, 사랑사구, 지상사구, 봉소상사구, 격자상사구, 양설상사구, 초생달사구, 포물선상사구, 초생달사연사구, 초생달사롱, 피라미드상사구, 복합형초생달형사구, 복합형종사롱사구, 돔상사구, 불규칙한 사구 사지 등 매우 다양하다. 이들 사구의 분포비율은 높이 5m이하 13%, 6~10m 17%, 11~25m 18%, 26~50m 14%, 51~100m 28%, 100m 이상 10% 등이다. 중국 건조지역에서 사구의 이동방향은 주로 주풍방향에 따르나 지역 지형 사구의 크기 및 형태 등에 따라서 이동사구형태에 차이가 많다. 사막화지에서 주요 비사방지기술(방사공법)은 생물 생태적 방사공법(식물피복방법 식재에 의한 방법), 물리적 방사공법, 화학적 방사공법 등으로 구분할 수 있는데, 생물 생태적 방사공법에는 초생법(봉사육초(封沙育草)), 관목 초생고사법(草生固沙法), 사구간 방사림대, 기간방사림대, 경지방풍림대조성 등이 있고, 물리적 방사공법에는 고방사원(高防沙垣) 및 저방사원 조성, 방사제방, 석력점토피복법 등이 있으며, 화학적 방사공법에는 고화제뿜어붙이기, 유사개량화학역제혼용법 등이 효과적인 것으로 분석되었다. 그 밖에도 관개 침사공법, 비사포착수로 구방사공법(溝防沙工法) 등이 효과적인 것으로 판단된다.

  • The trend and achievments of soil erosion control research in Japan were investigated through observation tours and reference work and following facts were found to be important aspects which should be considered in the soil erosion control research program in Korea. Experiments on forest and water relations, and ground water phenomena at the water source zone in Tokyo University. Studies on land-slides and erosion control dam in Kyoto University. Studies on mud-flow and snow avalanches in Hokkaido University. Studies on sanddune fixation and disaster damage prevention forests in Kyushu University. Studies on forest denudations in Nagoya University. Studies on Greening-works and soil erosion prevention chemicals in Tokyo Agriculture University. Training on planning of erosion control works and prevention of disaster damages in Forest Research Institute. Experiments on soil erosion phenomena and infiltration in Tohoku Branch, FRI. Experiments on erosion and surface stratum failure of steep slopes and their prevention methods in Railway Technical Research Institute.

  • The shelterbelts are very important to conserve and protect the sandy land, vegetation coverage, farmland, livestock and human life in the desertified land. The shelterbelts are constructed by the several row-plantings of high-adaptable species in the desertified land. The shelterbelts have various kind of type, and there are shelterbelts for conservation of farmland in dry the region, the protective shelterbelts (windbreaks for blowing-sand, artificial sanddune fixation by revegetation, and construction of farmland shelterbelts to protect farmland and pasture from wind erosion, etc.) in the semi-dry steppe, shelterbelts around the villages and oasis for sanddune fixation, shelterbelts for protection of railroads, and so on. The shelterbelts consist of main she1terbelts and minor shelterbelts. The main shelterbelts were constructed by being perpendicular to main wind direction, and the minor shelterbelts were constructed by being perpendicular to the main shelterbelts. Generally, the width of shelterbelts is 8~20m, and the number of row-planting is 4~10. The grid sizes of shelterbelts networks are $400{\times}400m$, $300{\times}500m$, $100{\times}200m$, and so on, and there are ventilation type and closing type in the type of shelterbelt. The width, number of row-planting, grid size and type of shelterbelt are selected by the local characteristics. The effects of shelterbelts are mainly the climate improvement and mitigation, such as prevention of occurrence of strong wind, cold wind and blowing-sand. And, the other effects of shelterbelts are effect of reforestation, increase of agricultural productions, establishment of greenbelts and green forests, construction of landscape-eco shelterbelts, improvement of life environment of local villages, supply of fuel wood and agricultural wood, land amelioration, effect of revegetation and restoration of desertified land, and so on. The kinds of the tree species mainly used for the construction of shelterbelts have differences between regions, but main species are Populus euphratica, Populus simonii, Populus bolleana, Populus tomentosa, Salix flavida, Salix mongolica, Tamarix chinensis, Hedysarum scoparium, and so on.
