Evolution of the Pearl River Course in Urban Area of Guangzhou and Its Influence on Ecological Environment
摘要
Abstract
Evolution of the Pearl River course in Guangzhou has a crucial impact on ecological environment. This paper integrated the data from ancient maps, historical records and modern remote sensing to build a graphic library for the representative river section of the Pearl River in urban area of Guangzhou, which quantitatively reflected the evolution characteristics of the urban river course. Combining the results from other relevant researches, the paper also deduced the evolution trend of the river channel. The results showed that the Pearl River channel narrowed with a rate of 0.6-0.8 m/a before the 1950s. Since then the whole section shape tended to be stable except parts of the course that changed greatly. At last, the paper discussed the influence of the river course evolution on urban ecological environment.关键词
