新疆土壤侵蚀遥感影像判读与几个独特问题

在新疆土壤侵蚀遥感调查中，对遥感影像的判读，采用了遥感信息与地学资料相结合、综合分析与主导分析结合、室内判读与专家经验及外业调查结合、分层分类判读的方法；根据新疆水蚀、风蚀、冻融侵蚀具有垂直分布规律的特点，在土壤侵蚀分类时主要考虑降水量、海拔高度和年均温等指标；列出了新疆土壤侵蚀分类分级影像特征；指出盐碱地的侵蚀分类与戈壁的侵蚀分级是有待研究的重要问题。

Recognition of Remote Sensing Images and Several Distinctive Problems for Soil Erosion in Xinjiang Autonomous Region

In remote sense investigation for soil loss in Xinjiang Autonomous Region, Remote Sensing Images are recognized by stratum and classification in combination of remote sense information and geoscientific materials, comprehensive analysis and particular analysis, indoor recognition and specialist's experience. In accordance with the characteristics of perpendicular distribution of water erosion, wind erosion and freezing melting erosion, the index such as precipitation, elevation and average temperature are mainly considered when soil erosions are classified. The paper lists the characteristics of remote sense images by classification and grade, and indicates that the erosion classification for saline and Gobi are important problems to be researched.
