Anthropogenic activities have an important effect on the natural coastlines of island cities as a result of urbanization and population agglomeration in developing countries. In order to identify the relationships between land use and coastline changes in the typical island city, this study used land use data, remote sensing technology, and geographic information system (GIS) technology to analyze the land use situation and coastline changes in the coastal zone of Zhoushan Island in China. The results show that, from 2012 to 2017, the coastal land area of Zhoushan Island increased from 121.54 km2 to 126.00 km2. New agricultural land accounted for the highest proportion of total land use growth (46.86%), followed by residential land, land for street, and transportation and industrial land. The length of the coastline increased from 137.98 km to 142.7 km. The indicators of agricultural land, industrial land, land price, and production coastline had a significant positive impact on the rate of coastline changes. Moreover, the coastline was more than just a natural coastline but also had 336 multiple functions in terms of production, daily living, leisure, and transportation. The study found that the rapid growth of tideland reclamation-based, land reclamation-based aquaculture, and the harbour/port construction-based logistics industry are the main reasons for the continuous changes in coastlines.

Abstract-China is undergoing a period of rapid industrialization and urbanization and a great number of migrant workers are moving into the city. However, their transformation is not complete with the geographical move. The paper is focused on two stages of migrant workers, which are geographical migration and identity transformation, to establish new evaluation indicators. Research was conducted in 22 settlements of migrant workers in Hangzhou to evaluate the degree of citizenization of migrant workers and its regularities in urban space.
