Abstract:

This study is to reveal the wetland system pattern of Huaihe River basin during the Sui-Tang (A.D.581-907) dynasties and Northern Song (A.D.960-1127) Dynasty, which were two millenarianism periods in Chinese feudal history. The data reflecting the wetland system pattern of Huaihe River basin during these two periods were mainly digitalized from "The Historical Atlas of China" and the data reflecting present wetland system pattern of Huaihe River basin were from "Basic Geographic Information Database of China". Based on ArcView GIS software, this study generated the sketch maps of wetland system pattern for the two historical periods and then discussed the pattern changes.From Sui-Tang to Northern Song, there were no significant changes for macro pattern of wetland system of Huaihe River basin. Wetland system was stable during Sui-Tang periods and relatively stable during Northern Song Dynasty. Natural wetlands in the basin, such as rivers and lake-marshes, maintained their relative stableness, which determined the stability of macro pattern of wetland system in the basin throughout the period. Stable wetland system pattern of Huaihe River basin provided good natural environmental background for the development of agricultural economy and social culture during that period. The major changes of wetland system of Huaihe River basin during these periods came from artificial wetlands.
