- Abstract:
-
Wuhan Metropolitan Area is one of the earliest resource-saving and environment-friendly society comprehensive experimental areas, it also the most important area of Yangtze River Economic Belt and the Central China Development Strategy. Understanding scientifically of land use change pattern of Wuhan Metropolitan Area during past decades is of greate significance for regional land use policy formulation and implementation. In this paper, traditional land use classes coding system is improved to adapt our research. By combining the improved coding system and land use dynamic degree model, we analysis land use data of 1990,1995,2000 and 2005 of Wuhan Metropolitan Area to recognize general pattern, trends in phases and regional heterogeneity of Wuhan Metropolitan Area since 1990. Results show that: (1) In Wuhan Metropolitan Area, area of cropland, forest and grassland decreased greatly, while water body and build up area increased during 1990 to 2005. Most decreased cropland was transformed to water body and build up area. (2) In different phases, it shows different land use change pattern in Wuhan Metropolitan Area: during 1990 to 1995, decreasing of cropland was the major characteristics; during 1995 to 2000, interconversion of cropland and water body was the main characteristics; during 2000 to 2005, cropland transformed to water body and build up area was the main characteristics. (3) Spatial heterogeneity of land use change in Wuhan Metropolitan Area is apparent: regions with large land use dynamic degree are centered on Wuhan City and counties beside it; as far as the land use dynamic degree for single land use class is concerned, regions with large cropland dynamic degree, forest dynamic degree and build up dynamic degree are centered on Wuhan City and counties beside it, while regions with large water body dynamic degree are centered on Xiantao City and Qianjiang City.
