【 摘 要 】

This study covers 1 city, 2 towns and 6 districts with the total area of 503,320.53 ha. Its outcome is eight decentralization criteria including soil type, slope, terrain elevation, soil layer thickness, mechanical composition, humus content, bio-climatic conditions and irrigation. 8 single maps have been built using GIS. These 8 maps are merged into a singular map of land unit. The results show that the study site has 130 land mapping units (LMUs), of which the LMU 49 has the smallest area of 100,88 ha and LMU 111 has the largest area of 35,423.23ha. Based on the land quality of LMUs, it can be said that in the study site, 80,282.02 hectares is suitable for annual crops, 2225.80 ha for Thanh Tra pomelo planting, 15528.11 ha for rubber, and 159377.1 ha for Acacia mangium planting.
