南迦巴瓦峰地区土地结构及土地资源的合理利用

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

从土地空间结构、土地数量结构、土地质量结构、土地利用结构和土地演替结构等方面对南迦巴瓦峰地区土地结构进行分析 ,结果表明 :该区土地结构独特 ,垂直分异现象明显 ,宜农、宜牧、宜林土地资源的数量和质量不平衡。在此基础上对土地利用中存在的主要问题及其合理开发利用与保护进行了探讨 ,并提出该区合理持续利用土地资源的重要措施为提高现有耕地单位面积产量。

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.
