基于RS和GIS的长江安庆段岸线资源评价

应用遥感影像结合GIS相关技术对长江安庆段岸线进行解译、分类，查清长江安庆段岸线资源分类长度，并采用岸前水深和岸线稳定性两个评价指标对岸线资源进行分等评价，兼顾岸前航道水域宽度和后方陆域场地条件两个限制性因素，综合确定岸线条件的优劣。评价结果：长江安庆段岸线总长度为249．6km，一级、二级优良岸线62．4km，三级岸线187．2km；开发条件较好的岸线有周家湾一套口、沟口-老湖塔和谭家沟-马船沟三段。最后结合安庆市经济发展背景、区位条件对安庆沿江岸线资源开发分段提出若干建议。

Riverbank Resources Evaluation along Anqing Reaches of Changjiang River Based on RS And GIS

The length of the classified riverbank resources along Anqing Reaches of the Changjiang River was figured out using remote sensing and geography information system.The exploitation condition of the riverbank resources along Anqing Reaches of the Changjiang River was evaluated through selecting indication such as water depth and riverbank stability,and then considered extensity rear water-front on land and water route width as other two limited factors.The result of the evaluation:the riverbank was 249.6km long,and the better was 62.4km.At last some suggestions on exploitation were put forward.
