Life Cycle Analysis of Sea Reclamation in Pearl River Estuary with Multi-source Remote Sensing Imageries
摘要
Abstract
Sea reclamation is regarded as an important means to seek reservation space from sea for development when regional socio-economy develops to a certain stage.The Pearl River Delta is one of hot spots for society and economy development in China.It has great importance for overall development in coastal zone to explore its spatio-temporal process and analyze the future trends of sea reclamation.This paper mainly discussed the spatio-temporal process and periodical characters of sea reclamation in the Pearl River Estuary with the multi-source Landsat imageries.The results indicated that the sea reclamation in Pearl River Estuary was mainly performed after the reform and opening up policy carried out in 1978.Four typical periods could be divided during the process of sea reclamation.Each period presented different total areas and growth rates,which was conclu-ded as follows:the areas of sea reclamation were about 18572 hectares,25528 hectares,13911 hectares,and 6723 hectares during the periods 1978—1988,1988—1996,1996—2005,and 2005—2015,respectively.By 2015,the total reclamation area in Pearl River Estuary was up to 64753 hectares.The hot spots of sea reclamation were especially concentrated along the west coastline. The potential regions of Pearl River Estuary for sea reclamation project in the future were further anticipated with the analysis of life cycle diagram.Results indicated that the coastal zone in Zhuhai and the former parts of coastal zone in Shenzhen would be the focus areas in implementing sea reclamation.In comparison,other areas will have relatively lower probability of sea reclamation. Furthermore,islands located in the Pearl River Estuary will be inclined to be connected with ter-restrial lands because of the continual reclamation,the sea reclamation process will be terminated at last.Life cycle analysis can provide scientific reference for making planning of sea reclamation in coastal zone.关键词
