Spatiotemporal Change Patterns of Coastlines in Xiangshan Harbor (Zhejiang, China) During the Past 40 Years

Abstract

ABSTRACT Li, J.; Pu, R.; Yuan, Q.; Liu, Y.; Feng, B.; Guo, Q.; Jiang, Y., and Ye, M., 2018. Spatiotemporal change patterns of coastlines in Xiangshan Harbor (Zhejiang, China) during the past 40 years. As special and important landscape bodies, tidal inlets possess many coastal resources. Consideration of the maintenance and protection of coastline resources and the environment is a challenging research topic, i.e. how to reasonably and scientifically exploit and use coastal resources. In this study, multitemporal Landsat images were used to explore and quantify relationships between the intensity of human activities and coastline changes. Specifically, (1) the spatial location, length, and tortuosity of coastlines in Xiangshan Harbor (XH; Zhejiang Province, China) tidal inlets, from 1974 to 2014, were extracted from satellite images; (2) the coastline change indices and the intensity of human activities in the tidal inlet areas of XH were calculated and assessed; and (3) the relationships between coastlin...
