Spatial-temporal Dynamics Analysis of Coastal Landscape Pattern on Driving Force of Human Activities: a Case in South Yingkou, China

This paper chooses south Yingkou coast as study area, some landscape pattern indexes such as water landscape dominant index, wetland landscape index, building disturb index and landscape stability degree are created to describe coastal landscape pattern change. Remote sensing images obtained in 1990,2000,2005,2010 and 2015 were employed as data sources. The result shows that water landscape which include salt pools, fishing ponds and tidal channel decreased, while terrain landscape include building land and grassland increased. Sea reclamation by human activities weakened coastal landscape characteristics in different sub-regions. The north sub-region has changed from salt pools, fishing ponds to town and industry landscape, the water landscape dominant index reduces to 0.15 and building disturb index raises to 45.40. The middle sub-region is just changing from water landscape to terrain landscape. Its water landscape dominant index is 0.56 and building disturb index is 10.30. The south sub-region still maintains water landscape. Its water landscape dominant index is 0.85 and building disturb index is only 4.40. The landscape stability degree of Iand II covered most areas.Idegree areas account for 35.73%. IIdegree areas account for 39.86%, while the areas which landscape types changed above 2 times, only account for 24.41%.
