摘要
在水土流失严重的区域,卫星影像是解决水土流失的问题的方法之一,通过解译卫星影像中的信息,了解水土流失的程度。利用遥感技术进行水土流失的调查,方便、快捷、可操作性强都是它的特点,非常适合区域调查与编图。文章以湖南某县为研究对象,利用分辨率更高的影像,并归纳总结识别技巧,提高识别的精度和速度。在完成解译后,对信息数据进行统计获得了与实际考察一致的结果,提高了解译的速度,对耕地等达到了较好的效果,提高了工作效率。
In areas with severe soil erosion,satellite imagery is one of the methods to solve the problem of soil erosion.By interpreting the information in the satellite imagery,we can understand the extent of soil erosion.The use of remote sensing technology for the investigation of soil erosion is convenient,fast and operable.It is very suitable for regional investigation and mapping.This article takes a county in Hunan as a research object,uses higher resolution images,and summarizes recognition techniques to improve the accuracy and speed of recognition.After the interpretation is completed,the statistics of the information data are consistent with the actual investigation,and the speed of understanding the translation is improved,which achieves a better effect on the cultivated land and improves the work efficiency.
