LAND RESOURCES AND IT' S DEVELOPMENT POTENTIAL OF DRY-HOT VALLEY IN JINSHA RIVER

论述了金沙江干热河谷（云南段）土地资源数量、质量及其农业开发潜力，并提出其开发利用途径及合理布局建议，供该区农业综合开发和研究参考．

For discussing the current situation of the land resources in dry-hot valley of Jinsha River in Yunnan Province,land resources types,quantity and quality are involved in this paper,as well as the land development potential for asricultrue is also evaluated. There are 33. 9 ×104 ha land,of which 22. 8 ×104 ha land can be developed for south-subtropics cash crop,soil and water conservation coppice,etc., in this area. Sufficient light resources,aboundant quality of heat and a wide area of undeveloped dry slope land and barren upland symblize development potential of the land resources. It's exploitation is limited by a severe lacking of water and soil and water erosion in rainy season. In accordance with the land resources characteristics and the limited factors,it's utilization way and rational allocation are presented as well.
