摘要: 城市湖泊作为一种重要的生态和旅游资源,其变迁趋势对城市的发展影响深远。为研究武汉都市发展区湖泊变迁情况,引入2013年6月获取的Landsat 8卫星数据,结合都市发展区1975—2013年近40 a 30多期遥感影像作为数据源,利用NDWI和谱间关系法,结合目视解译的方法提取区域内68个湖泊的时空信息,详细研究湖泊面和湖泊边界线的变化情况,基于GIS的空间分析技术和RS的变化检测的方法建立湖泊变迁专题图,并利用景观学指标分析湖泊变化原因。结果表明研究与武汉市政府水资源统计信息相符,为武汉市湖泊资源的保护和可持续发展提供了即时依据。

Abstract: Urban lake is an important ecological and tourism resource. Its variation has profound impact on the city’s development. The variations of lake surface and lake boundary in Wuhan are researched in detail by using NDWI and TM2+TM3> TM4+TM5 method in association with visual interpretation to extract the spatio-temporal information of 68 lakes. The research is based on Landsat 8 satellite data obtained in June 2013 and remote sensing images from 1975 to 2013 in the urban development area in Wuhan. Furthermore, thematic map of lake changes is given by using GIS spatial analysis technology and RS change detection method. The causes of lake changes are analysed through landscape indices. The research result is consistent with the government statistics of water resources in Wuhan city. It is also an instant basis for the protection and sustainable development of lake resources in Wuhan city.

Key words: Wuhan, lake change, Landsat 8, GIS, thematic map
