Abstract

The Socialist Republic of Vietnam is located in subequatorial monsoon climate region, however, due to the large extent of the country from north to south its climatic conditions vary significantly. The region nature is rich and diverse. More than 80 % of the country’s territory is occupied by low and subdued mountains covered with tropical forests. Forest reserves are being created for studying these mountains. The largest in area is the Kim Hy Nature Reserve, where we have done our research for determining the forest land categories. A digital map of an object was developed in order to define the area of each forest land category. The results of photogrammetric plotting of satellite data were the initial information for map’s creation. A database of the reserve’s forest lands has been created. Reserve’s borders and territories occupied by natural and artificial forests, wastelands, agricultural lands, residential buildings, water bodies, etc. have been established. Everything has been done with the use of the modern GIS technologies. The total area of the reserve is 15416 ha, 90 % of which is forests. The forest fund of the reserve is dominated by forest stands of natural origin (90 %), artificial forests occupy only 4 %, wastelands cover 6 %, other lands – 10 % of the total area. It is defined that natural origin forests of the Kim Hy Nature Reserve are old-growth, therefore, they need conservation and rational management.
