【摘要】 在实践的基础上,探讨利用CBERS-02星遥感图像,结合GIS技术实施快速、准确、经济的大范围生态环境调查,尤其是土地利用/覆盖状况调查。通过对遥感图像处理和信息提取,查明了研究区2000~2004年期间土地利用/覆盖状况及其动态变化,建立了研究区生态环境本底数据库。在综合分析研究区生态环境状况及其动态变化基础上,探讨了林地、耕地、草地等土地利用/覆盖发生变化的原因。论文认为,应用3S技术,尤其是应用多时相遥感技术进行生态环境本底调查,可达到快速、高精度动态监测的目的,为四川省生态环境建设提供科学的依据,同时也证实CBERS-02图像在生态遥感动态监测与评价中的实用性。更多还原

【Abstract】 Based on the practice,the authors discuss using CBERS-02 image data to acquire some information such as ecological environment status by means of remote sensing and GIS,and the ecological change situation from 2000 to 2004 in Sichuan province,especially land use / coverage survey.By the image process and interpretation,the dynamic change information is picked up and the background database of the ecological environment is founded.The authors analyze and discuss the Sichuan ecological environment status and dynamic change monitoring,and explain the change reason of forest,plow land and lawn.Due to the combination of advance techniques and expert’s experience,especially the application of different time RS technology to survey ecological environment status,so the result is reliable and reasonable.Meanwhile,the result also confirmed the practicability of CBERS-02 image in the dynamic monitoring of ecological environment.更多还原
