Abstract: The urban wetland park is one of important land resources, praised as "the kidney of the city", which has multiple functions of ecological restoration and purification. Therefore, the land use monitoring in urban wetland parks is of great significance to environmental improvement, rational utilization of land and protection of wetland resources. The dynamic change of land use was monitored by ENVI supervised classification in Chengdu Bailuwan Wetland Park. Results showed that the land classification in 2012 was as follows:vegetation, cultivated land and half-bare land, creation and bare land,respectively occupiying 42%, 33% and 25% area of the park; In 2015, the land classification ratio turned to 42%, 20% and 22% respectively, and the water body increased by 16%. The cultivated land, vegetation and water area in wetland parks increased year by year, and the land use structure became more reasonable. With the help of dynamic monitoring and analysis of land use change by remote sensing technology, the utilization of wetland park resources would be more rational, which had great significance for the development of urban wetland.
