Abstract:: In order to reveal the spatial and temporal changes of coastline in Yantai City and the change of spatial pattern of land use over the past 40 years, we extracted the length of the coastline with an extension of 5 km along the shore line during four different periods in Yantai City, along with data from the survey on land use. By using Landsat MISS, TM, ETM+ remote sensing data and extracting land types in the two periods of 1973 and 2014, we also analyzed the current situation and characteristics of space-time of land use and cover change (LUCC); the monetary evaluation on landscape has been made based on Costanza’s ecosystem services and Chinese land ecosystem services to value per unit area of coefficients. The results showed that: (1) the total length of coastline has been increasing by 55.976 km during the past 40 years, of which the largest rise took place in artificial coast and the natural coastline of bedrock and silt have been significantly reduced; (2) the total land area had increased by 95.661 km² over the past 40 years, and land reclamation was the main reason for leading to increased land area construction, while the areas of wetlands, forest land and water had substantially reduced; (3) the change of the land use in the total value of ecosystem services has caused the loss of 1 586 360 yuan, of which the loss of ecosystem values of wetlands and woodland make up the largest proportion, that a large number of natural wetlands have been used as building land and that protection of farmland has caused changes in the ecological value of different land cover types.
