Remote Sensing Analysis of Surface Coverage of Typical Urban Areas around Dianchi Lake

As the largest plateau lake in Yunnan province, Dianchi Lake plays an important role in water environment protection and pollution control. For surface coverage change of typical towns around Dianchi Lake, there are some things which have great significant for providing data support for timely optimization control scheme, such as remote sensing detection technology, quick understanding of pollution sources, and realtime monitoring of Dianchi Lake pollution. Selecting an typical town Jinning as research area, which is around Dianchi Lake, and based on Landsat8 to remote sensing image of surface coverage classification information extraction, use confusion matrix compared with maximum likelihood method and visual interpretation for classification accuracy. From this article, we can know that Landsat8 image can be quick and efficient extraction of urban surface cover classification information through visual interpretation. Landsat8 also can ve applied to Kunming and Chenggong, both of them are in Dianchi Lake watershed. This article prouioles technical support of management of Dianchi Lake watershed protection of macroscopic dynamic monitoring,amd also provides decisionmaking information for planning and management evelopment of the town in Dianchi Lake watershed.
