利用遥感技术调查六盘山涵养林

Remote Sensing technology in the research of water source-conserving forests in Liupanshan Mountains

采用Landsat ETM+数据,进行区域1:5万比例尺的基础土地利用调查,通过影像处理、野外调查、解译、质量控制、结果分析几个步骤,得到六盘山地区水源涵养林的现状,说明退耕还林工作对六盘山及周边地区的生态、气候等环境因素的重要性。

In this work, we use the Landsat ETM＋ data for 1：50000-scale primary land use research of the Liupanshan Mountains. By image processing, field visit, interpretation, quality control and result analysis, the present situation of the water source-conserving forests in Liupanshan Mountains is known. All facts shows that reuse the farmland for forestation is very important for the Liupanshan Mountains and its surrounding region, as well as for their ecosystem and climate.
