| 摘 要： | 浑善达克沙地是我国主要的沙尘暴源区之一,近代浑善达克沙地的生态环境脆弱,沙化日益严重,已成为困扰北京沙尘的主要源头之一,严重影响了京津、乃至整个华北地区的生态安全以及当地生态、社会和经济的可持续发展,这一问题引起广泛的关注。DInSAR技术是重要的监测沙漠高程变化的技术,本文利用DInSAR技术,在对比分析6景ERS-2和EnviSat雷达图像基础上,对2004年10月26日和2005年10月11日两幅EnviSatASAR影像进行了干涉处理,经过配准、平地效应改正、滤波、相位解缠和地理编码,得到高程形变模型。根据研究结果,大部分地区高程是降低的,少数地区高程是升高的,这与2005年春天沙尘暴高强度发生的情况相一致,推广利用DInSAR技术实现沙漠地表形变监测具有重要作用。

| Abstract: | The DInSAR technique is used for monitoring the desert height changes to study sandstorms. Hunshandake Sandy Land, as the
test area, is one of the main sources of sandstorms in Beijing. In order to study the sandstorm source and its impact, a pair
of EnviSat ASAR images of Oct. 11, 2005, and Oct. 26, 2004, is processed on the basis of analysis of six ERS-2 and EnviSat
radar images. After the image configuration, flat earth effect correction, data filtering, phase unwrapping, and geo-coding,
a deformation model over Hunshandake desert is built. According to the results, the height decreased in most areas and increased
in a few areas, which basically coincides with the strong sandstorm appearing in Beijing in the Spring of 2005. The results
show DInSAR has an important role in monitoring of desert surface deformation. |
