With the development of remote sensing technology, monitoring and dynamic analysis of ponds is becoming easier to obtain which is very important for regional LUCC research and water resource protection. Taking Honghu city in Jianghan plain as study area, the multi-scale segmentation was carried out based on object-oriented method according to the Landsat TM remote sensing data in 1990, 2000 and 2009. The spectral, space, texture features were used as well as the expert system was also combined for the extraction of ponds information. Remote sensing monitoring and spatial-temporal evolution analysis were carried out on the change of pond in Honghu city. The results showed that ponds area performed an increasing trend in the past 20 years. The increased ponds area in 1990—2000 and 2000—2009 were 306.53km2 and 379.69km2, respectively. The increasing pond area decreased with increasing distance to lakes, and the increasing pond area usually changed from farm land, lakes and rivers. Object-oriented ponds information provides important reference data in monitoring region environment and resources.
