Temporal and spatial evolution characteristics of the coastline in Sanmen Bay, Zhejiang in past 100 years

Abstract

Abstract: Based on historical topographic maps, charts and remote sensing images since 1913, 10 periods of coastline data covering Sanmen Bay were obtained and analyzed using GIS and spatial analysis tools. The temporal and spatial evolution characteristics of the coastlines in Sanmen Bay during the last 100 years were investigated. The results show that: (1) The changes of coastlines mainly occurred in the inner bay. The reclamation activities, mainly including harbor construction and island-land connection, led to a total land area increase of 231.42 km². (2) The total length of the coastlines was reduced by magnitudes of 161.99 km and 121.36 km for the mainland and islands, respectively. The average annual change intensity of coastlines changed from -0.05% to -1.85% in the last 100 years and the most intensely changes occurred in 1971-1980 for mainland coasts and 2006-2010 for islands. (3) The straightening of coastlines was caused by meandering cutting as a result of the continuous decrease of natural coastlines. The artificial degree of mainland coastlines continued to increase, which was much higher than that of island coastlines. (4) Population growth, economic development and policy guidance were found to be the main driving forces for the coastline evolution in Sanmen Bay.

Key words: Sanmen Bay, coastline, temporal and spatial evolution
