摘  要:以北京市平原区为研究区域,利用北京1号卫星(Beijing-1)融合数据,研究了非正规垃圾场的影像特征,建立了非正规垃圾场在小卫星影像上的判读标志,通过人机交互和计算机自动检测方法对北京地区的非正规垃圾场进行了判读分析和变化检测试验研究。验证发现:利用Beijing-1小卫星的全色和多波段融合影像对非正规垃圾场的识别精度可达90.3%;由于非正规垃圾场影像特征的不确定性,计算机自动变化检测方法不能替代人机交互判读,但可提高人机交互识别变化的效率。Due to urbanization increasing, the quantity of solid wastes in Beijing is increasing rapidly and leads to large numbers of informal solid wastes dumps. Solid wastes in these sites are usually dumped in the open air without certain environmental conservation measures, which influence the urban environment and human healthy badly. It is absolutely necessary to monitor these dumps in order to take some effective measurements to dispose them. Remote sensing technology can provide a rapid and effective way to identify and monitor the dumps, owning to its characteristics of objectivity, real-time and macro-scope view. With high spatial resolution, high frequency of revisiting and broad coverage range, Beijing-1 Microsatellite image is an important data source for urban environment monitoring. Taking the flat plain area of Beijing as study site,this paper establishes the interpretation keys of informal open-air solid waste dumps through studying their characteristics based on Beijing-1 fusion images. Via visual interpretation and automatic change detection methods, the authors studies the location and change of the open-air solid waste dumps. Compared with the field investigation data, it shows high accuracy ( about 90.3% ) of the indoor visual interpretation result using Beijing-1 images. However, on account of the uncertainty of the solid waste dumps characteristics, automatic change detection method can just be utilized to decrease the work of visual interpretation to find the location instead of replacing it completely.
