This paper is to study the purification space related waterscape in Chinese gardens. By tracing back the origin and evolution of the purification from the literature, several categories of the purification space related waterscape in Chinese gardens can be classified based on the layout plan and the evolution of construction technique. In general, the purification space related waterscape has been evolved in two styles: the natural style and the artificial style. The techniques of water management and design criteria adopted for both styles are analyzed and compared in this paper. Due to its long and in-depth influence on the east Asian countries, the purification space related waterscape still exists in some of the classical gardens in China, Japan and Korea.
