1987-2019年钦江三角洲土地利用变化及其对海岸线的影响
Land Use Change and Its Impact on Coastline in the Qin River Delta from 1987 to 2019
摘要
Abstract
The estuarine delta is a densely populated and economically developed region,and its land use change research is of great significance for regional economic and social development.In this paper,the remote sensing images from 1987 to 2019 are classified,and the digital coastline system is used to analyze the change rate of coastline,and then explore the relationship between the two and the influencing factors.The results indicate that:From 1987 to 2019,the area of construction land,wetlands,and aquaculture ponds increased,with the area of construction land increasing by 57.34 km2,while the area of cultivated land,terrestrial vegetation,and water bodies decreased.From 1987 to 2019,the annual average rate of shoreline advancement was 33.90 m/a,and the direction of shoreline development was seaward extension,indicating that the shoreline was in a state of growth.The change of coastline is strongly associated with the change of land use type.This study provides reference for the protection and utilization of natu-ral resources in the Qin River Delta.关键词
