摘　　要：本文介绍了紫阳县城滑坡监测工作的技术方案及数据处理方法和结果。通过各种方案的对比分析．对监测网的各种技术方案的选取提供了依据．文中所提出的依据稳健估计原理、利用Ｓ变换解决参考基准的定位问题．是基准网非稳定情况下进行监测数据处理的成功方法，颇有借鉴意义。This paprt deals with the monitoring work for slide movements in the area of Ziyang City and gives outits technical design,the methods of processing data and the resurts. Based on the study of various technical designs, the suggestion how to choose them was put forward. The principle of robust estimate for data and usings transformation to solve the problems related to reference positioning are proposed in this paper, and it hasbeen proved that they are helpful and successful for the monitoring data processing under the unstability ofreference network.
