Abstract Chingmei stream, one of the main tributaries to Hsintien stream, locates between Taipei basin and Peishih stream basin. The low plain surrounding its lower course is of flood-prone area. However, due to its closing to the new subcenter district of Taipei city, the plain has been intensively developed and heavily populated, and is bound to be more intensified following the complete of Feitsui reservoir in 1987. Looking back to its history, unfortunetly, serious flood damages have occurred many times in the downstream area. Apparently, there must be misuse of water and land resources existing in this basin. This paper is divided into two main parts: Part 1 deals with the hydrologic characteristics of the basin streamflow and water resources management. A variety of rainfall and streamflow frequences were estimated based on both the extreme value type I model and log-Pearson type III model. Part 2 deals with the land use pattern and its problems and the evaluatin of land resources. From the geographical viewpoint, the optimum measure for land resources management of the basin would be providing a variety of recreation opportunity to meet the wide demand for recreation activities of the increasing population of the Taipei metropolitan area.
