- Abstract:
-
Using the data of Landsat TM5 (1988, 1995, 2000 and 2006) and Landsat TM8 (2013), the evolvement and its driving factors of landscape pattern in Jiangbei District of Nanjing City in the past 25 years were explored based on the technology of remote sensing and GIS and the theory of landscape ecology. Some indices were chosen to describe the changes of landscape pattern, such as the number of patches, the average area of patches, edge density, average dimension index, shannon diversity index, shannon evenness index and so on. The results showed that the landscape pattern in Jiangbei District changed greatly from 1988 to 2013. The woodland and construction land increased, while the farmland decreased, and the area of other types fluctuated slightly. Under the action of human disturbance, aggregation index and patch cohesion index decreased, while Shannon’s diversity index and Shannon’s evenness index increased in this area. The growth of population, economy and industry together with the adjustment of industrial structure are the main driving factors on the evolvement of landscape pattern in Jiangbei District of Nanjing City.
