Analysis on Land Structure and its Rational Exploitation in the Mt.Namjagbarwa Region

There are more than two thirds land resources of the whole land area in mountainous region in China. Thus, There is important theroretical significance and practical value in study on land structure in order to exploit it rationally and protect it effectively as well as to gain maximum economic, ecological and social benefits. The Mt.Namjagbarwa region abounds in vast land resources. According to the data obtained durin the Scientiic Investigation of the Mt. Namjagbarwa, land structure including land space structure ,land quantity structure,land quality structure,land_use structure and land succession structure in the region is analyzed in the paper.The result shows that the land structure in the area is distinctive with apparent vertical differentiation and the quantity and quality of land suitable for farming,forestry and animal husbandry is inhomogeneous.The main characteristics and problems in land_use, its rational exploitation as well as the main directions and measures are also discussed and provided.The important countermeasure for rational and sustainable exploitation of the land is to raise per unit area production level of the existing cultivated land, prohibit deforestation, protect natural forestry and strengthen the grassland construction.
