内容 研究概要:Environment of a river basin in Sri Lanka was analyzed by digital mapping, CIS, and remote sensing data. The "Walawe" river in selected basin is one of the major rivers in Sri Lanka. It brings water for one of the most active agricultural settlement area and also for number of other smaller reservoirs. The river basin covers over 2400 sq. km. area of land from central mountains to south coast. Vegetation distribution of this area was classified using digital data of Landsat MSS, and produced the other related Geographical data files into a GIS data base with 5x5 sec ground resolution. Significant features in; land cover, elevation, slope, soil, climate, and other social phenomena were observed and inter-relations of these elements were analyzed by GIS. Thematic maps such as; soil+paddy, slope+forest, were produced using data file of the GIS data base. The results indicated the; environmentally poor present vegetation structure, neediness for forest conservation and reforestation, and better management of soil and water resources of the area. The extensive use of water and soil of the area for agriculture also discussed.
