快速城市化地区的土地利用与景观格局演变特征分析——以杭州市区为例
Analysis on the Changes of Land Use and Landscape Pattern in Rapid Urbanization Region
摘要
Abstract
Take the rapid urbanization region Hangzhou City as an example, and based on the platform of Erdas 8.7, Arcgis 9.0 and Fragstats3.3 software, TM imageries in 1991, 1996, 2002 and 2005 had been interpreted. The characteristics and changes of land use and landscape pattern were explored during the past 15 years, by means of theory of landscape-ecology and the method of quantitative analysis. The results showed: first, land use structure changed greatly, the farmland decreased, while the built-up areas increased significantly from 5.83% in 1991 to 21.81% in 2005; second, land information entropy increased considerably and had significant correlation with urbanization rate, the coefficient of determination reached 0.9, which indicated that land use developed disorderly under the disturbance of human activities; third,the landscape structure and landscape heterogeneity in Hangzhou city changed greatly. The numbers of patches and diversity index and fragmentation index increased, while the dominance index decreased obviously. Dimension data analysis suggested that the agricultural landscape,forestry landscape and waters landscape tended to increase, which indicated that the shape of these landscape patches became complicated.Construction landscape first increased and then decreased.关键词
