摘要
应用机载合成孔径雷达监测洪水势态，离不开洪灾监测信息系统的支持，两者有机的结合，能充分发挥遥感和地理信息系统在防洪减灾应用中的优越性。本文以小清河滞洪区为实验区，从系统目标、数据层及其来源、数据编码、分析模型等几个方面，介绍了该区洪灾监测信息系统的建立情况。
Through the information of forestlands obtained from remote sensing pictures of 692 land patches, this paper has studied the forestlands classification in the method of self-organizing neural tree model under the support of GIS. The results show that this method of classification has so many advantages, such as speed, accuracy and tolerence.
