摘要
根据2004年的TM遥感影像,在软件ERDAS 8.6下解译出万州地区的土壤侵蚀等级分布情况并在ARC-VIEW3.2进行分析统计。通过与1995年的土壤侵蚀调查数据进行比较分析,发现万州区的土壤侵蚀状况明显好转,并对万州区土壤侵蚀状况发生变化的驱动因子进行分析,多角度阐明了万州区土壤侵蚀变化的原因。为万州区今后水保工作的开展具有一定的指导意义。
Based on TM image of 2004, the spatial distribution of soil erosion ranks of Wanzhou district has been interpreted under the software of ERDAS 8.6 ,and the date was analysed under the software of ARCVIEW3.2. By comparing the result with 1995＇s,a meliorating trend of soil erosion in Wanzhou was found. Moreover, the driving factors of soil erosion variation were analyzed deeply and were illuminated in multi-aspect. And the study has significant guidance for soll and water conservation in Wanzhou district.
