西藏自治区历次沙化调查技术方法变化及发展方向研究

Study on Change and Development Direction of Each Desertification Investigation Techniques and Methods in Tibet

西藏自治区是我国沙化土地集中分布区域之一。自1994年以来,西藏自治区先后开展了6次沙化调查,为紧跟我国生态监测技术发展水平,沙化调查技术标准及方法与时俱进,不断革新进步。现就西藏自治区历次沙化调查进程,以及技术标准和方法的变化及影响进行系统梳理和分析,同时展望下阶段沙化调查监测技术标准与技术方法发展方向,以期为全国沙化调查监测技术发展提供借鉴。

Tibet is one of the areas with concentrated distribution of desertificated land in China. Since 1994, Tibet has conducted successively six desertification investigations, and the technical standards and methods of desertification investigation in Tibet have been keeping pace with the times and constantly innovating and progressing in order to closely follow the development level of ecological monitoring technology in China. Now, the progress of each desertification investigation in Tibet, and changes and influences in technical standards and methods are systematically combed and analyzed. At the same time, the development direction of technical standards and methods for desertification investigation and monitoring in the next stage is put forward, with the aim to provide reference for the improvement of national desertification investigation and monitoring techniques.
