Abstract

Identifying suitable site for tree planting for watershed protection was carried out at the Doitung Development Project, Amphoe Mae Chan and Amphoe Mae Xai in Chiangrai Province, the project area is 149.625 sq.km. area. The Geographic Information System Tutorial (GIST) software AIT were used with microcomputer to managed and analyzed the data in 0.25 x 0.25 sq.km. raster format. Those data are elevation, slope, aspect, roads, soil texture, water bodies and landuses. The assumptions of area which are suitable for tree planting are deforested area or swidden area which elevation greater than or equal to 800 metre above mean sea level or slope area greater than 60%. The relavanted informations are land use, slope and elevation above mean sea level. The resulting map of the area that are suitable for tree planting is displayed and found that the area is 33.625 sq.km. (21,015.625 rai).
