- Abstract:
-
The coastal zone has become one of the most concentrated regions of human production activities because of its abundant water and soil resources. In recent years, significant changes of land use types have occurred in coastal zone due to the strong exploitation and utilization of human activities. With the help of RS and GIS technologies, we studied the changes and transfer characteristics of land use types in the coastal zone of Jiangsu Province over the recent 19 years based on the remote sensing data of 1995, 2002, 2009, 2013 to provide a reference for the rational utilization of local land resources and the adjustment of land use structure and achieve the harmony between land exploitation and ecosystem protection. The result show that: (1) cultivated land is the main land use type in the study region, followed by artificial pond, and the areas of the forestland, grassland and beach are relatively small; (2) the main characteristics of land use change are the decrease in cultivated land, water body and beach and the increase in construction land and artificial pond; (3) transfer characteristics of land use type is different in different periods. Overall, the cultivated land, construction land and artificial pond are closely linked, and they have a large amount of area to transfer among three types of land use; The water body and the beach mainly converted each other; the cultivated land is the main transfer target and source of the forestland and grassland; (4) the total value of ecosystem services in Jiangsu coastal zone hac been decreasing over the recent 19 years, and the decreasing rate rose.
