摘要:

西藏"一江两河"中部流域地区是我国沙漠化强烈发展的地区之一。根据"一江两河"综合开发部署和沙漠化的实际状况,制定了本区沙漠化防治的目标、对策和治沙工程布局。"八·五"、"九·五"期间治理沙漠化土地8.46万ha。治沙工程实施后,综合效益指数将比1990年提高33.7%,系统功能状况与效益水平在整体上提高1/3。

关键词: 西藏"一江两河", 土地沙漠化, 治沙工程

Abstract:

The central "One-River-Two-Tributaries" basin in Tibet is one of the severe desertification areas in China.Based on the comprehensive development planning and the real situations of desertification in the area,the desertification control objective,measures and engineering layout were put forward.According to this objective,some 84 600 hectares of desertified lands will be brought under control in the eighth and nineth five-year-plan periods.Once this project hsa been completed,the comprehensive benefit index will be rised by 33.7% sa compared with 1990.As a whole,the systematic function and benefit level will be rised by one third.

Key words: One-River-Two-Tributaries, Land desertification, Sand control project
