摘要
北京作为中国首都,生态环境受到很大的关注,最近几年,北京市加大力度进行西北部山区矿山治理以及生态恢复,以改善首都的生态环境,北京西北部山区作为首都的生态涵养区,其森林资源的调查和监测是十分必要的。以北京市西北部山区为主要研究区,以"北京一号"小卫星遥感影像为主要信息源,参考航空影像与地面调查数据,采用人机交互式解译方法,对北京市各区县森林生态系统资源进行调查监测,统计2006年北京市各区县森林资源的地类面积,将调查结果与2006年地面调查结果进行对比,进行精度分析和综合评价。评估"北京一号"小卫星影像在森林资源调查和监测中的应用能力。进而为森林资源评价、重大生态环境建设工程规划及效益分析等方面提供支持。监测分析结果显示:应用"北京一号"小卫星遥感影像作为信息源,进行北京森林生态系统资源分析与研究是切实可行的,是一种多快好省的方法。针对北京而言,有林地、疏林地、灌木林地等的分类精度均在90%以上,可以实现森林资源的常规监测分析,对北京森林生态系统资源动态监测的快速进行具有实用性。
As China＇s Capital,Beijing＇s ecological environment gains tremendous attention.In recent years,Beijing makes great efforts on northwest mine management and ecological restoration,so as to improve the ecological environment of the capital.As the ecological conservation zones,it is necessary to investigate and survey the forest resources of the north-west mountain area in Beijing,This research takes Beijing northeast the mountainous area as the main research area,using ＂Beijing-1＂ Micro-satellite Remote Sensing Image as data source,taking ground survey data of forest resources and the aerial image for reference,and using the method of man-machine interactive interpretation.Comparing with the result of ground survey data of Year 2006,the paper analyzes accuracy and conducts integrated evaluation,evaluates the ＂Beijing-1＂ Micro-satellite image application＇s ability in surveying the forest resources.The report further provides help in forest resources evaluation,planning and benefit of importance environment construction project.＂Beijing-1＂ Micro-satellite as a good method shows its advantage from the survey result.For Beijing,the closed forest land,the wooded land,the shrub land and so on classified precision above 90%,may realize the forest resources routine monitoring analysis,carries on fast to the Beijing forest ecosystem resources dynamic monitor has the usability.
