| 摘 要： | 利用2003/2008/2013年中、高分辨率,多源、多尺度遥感影像、地理国情普查数据以及其它专题资料,采取内、外业相结合的方式,利用决策树模型提取不同地区沙化信息。最终通过该沙化信息了解研究区沙化现状,实现沙化动态监测,并结合相应的防沙治沙措施分析不同方法对不同地物类型防沙效果的优劣,方便决策者因地制宜地制定防沙治沙方法,以便取得最优的治理效果。此外,在现有环境稳态的基础上,建立沙化转移矩阵,在环境稳态不改变的条件下,预测研究区沙化趋势。结果表明,2016年沙化状态有所减轻。

| Abstract: | A decision tree model is proposed to extract the desertification data from different regions by means of fieldwork and office work .The data covers kinds of high‐resolution ,multi‐scale remote sensing images and the geographic census information in the years of 2003 ,2008 and 2013 .T hus the desertification information in given region will be obtained in order to make the dynamic monitoring . The relative preventions against different regions decide the final countermeasure in the optimum way .In addition , based on the current environmental steady‐state ,this paper establishes a desertification transfer matrix to predict the desertification trend in the targeted region .The results show this trend has been proportionally reduced since 2016 . |
