Land Use Change of Kunming Based on Landscape Ecology and NDVI

Land use change plays vital roles in regional, social and economic development and global environmental change. Based on three different phases of TM images acquired in 1992, 2000 and 2006, this paper takes Kunming in China as a case study to analyze spatial change of land use and to evaluate urban environment quantitatively by combining Landscape indices and NDVI. Following the theory of landscape ecology analysis, 4 typical landscape indices are abstracted to evaluate the environmental effects and spatial feature changes of land use. With the development of urbanization process, urban environment issues have attracted more attention. This paper introduces the NDVI and green index to demonstrate the urban expansion and environment state. The study provides a better research case of revealing land use change in the industrialization and urbanization process in plateau region and research results are beneficial to promote the development and regional planning of urban.
