广东省围填海历程及其环境影响研究

Study on the Process of the Sea Reclamation and Its Environmental Impact in Guangdong Province

围填海是沿海地区获取土地资源的重要途径,但过度或不合理围填海将会给近海生态环境造成不同程度的影响。文章对广东沿海1949-1990年、1990-2000年、2000年至今三个阶段围填海进程及其类型进行了分析,总结了围填海对海岸线、近海水动力和水环境和近海生态系统的影响。

With the fast development of coast economy and continuous increasing population pressure , sea reclamation has been an important way to obtain land resources on coastal areas. However ,excessive expansion and unreasonable reclamation will make a threat to the marine ecological system. The sea reclamation process and its types, which the three stages of 1949-1990, 1990-2000, 2000 to present, were analyzed, and the influences of the sea reclamation on the coastlines , hydrodynamic and water environment adjacent area , and coastal ecosystem were discussed.
