摘要
自20世纪70年代以来,锦州湾附近海域实施大量填海造陆工程,在促进经济发展的同时也对生态环境造成不良影响,有必要对锦州湾附近海域的围填海状况进行连续监测。文章以5个时相的Landsat TM遥感影像作为主要数据,利用RS和GIS技术手段进行锦州湾附近海域海岸线的提取,系统分析锦州湾围填海海岸线的演进过程,并从海岸线长度和海岸线曲折度等方面对锦州湾围填海开发特点进行定量分析。
Since 1970 s,a large number of land reclamation projects were implemented in the waters near the Gulf of Jinzhou,which have promoted the economic development as well as causing the adverse ecological and environmental effects.It is necessary to monitor the status of the reclamation areas near the Gulf of Jinzhou.This study based on five phases of the Landsat TM remote sensing images as the main data were extracted in the Jinzhou Bay coast line,by using RS and GIS technology,the system analysis of Jinzhou Bay reclamation coastline evolution process,and the length change from the coastline.Quantitative analysis on the characteristics of reclamation development was carried out in Jinzhou Bay by using the structure of the sea and shoreline twists and turns.
