Land Use Change Analysis of Coastal City:A Case Study of Yancheng
摘要
Abstract
Land Use/Cover Change(LUCC) is a core issue of global change and regional sustainable development research. Coastal zone is the land-ocean interaction area, which is much more sensitive to human activities. The exploration of coastal LUCC is significant to meet the challenges of the environment and nature. Yancheng, a typical research area in Jiangsu coastal areas, is selected to characterize coastal land-use and land-cover changes with five series of Landsat MSS/TM imagery from 1978 to 2007. The classification schema is newly-developed based on the existing schemas as well as the geographical background of Jiangsu coastal areas, and PCA classification and post-classification comparison are used to perform image classification. With the series of land use/cover change results, the land use structure, land use change quantity, land use change rate and spatial change pattern are analyzed and calculated based on GIS. The results show that:(1) The change of land use was significant during the study period, the land use structure of Yancheng was relatively stable;cultivated land was the main agricultural land use type, but urban construction land had a sharp increase on land use amount and land use proportion in recent years;(2)The land use change quantity and change rate were very significant in different periods. The change of construction land was the most significant, and the urban construction land increased 3.34 times, i.e. from 167.01 km2 in 1978 to 725.19 km2 in 2007, and at the same time the land use change rate reached 15%from 2004 to 2007. (3) From the perspective of spatial change pattern, the central urban districts of Yancheng, especially the Economic Development Zones and newly-incorporated Yandu District, had a rapid urban expansion;simultaneously some newly-developed coastal ports such as Binhai Port, Dafeng Port and coastal towns nearby also had a high-speed growth.关键词
