甘井子区土地利用及景观格局研究

Study on Land Use and Landscape Pattern in Ganjingzi District

以2005年和2015年土地利用数据为基础,利用GIS技术及景观格局指数来研究甘井子区10年间土地利用景观格局的动态演变规律。结果表明:(1)甘井子区各类型用地变化显著。其他农用地和建设用地增加最大,自然保留地、园地减少幅度大。(2)景观斑块数量、斑块密度、蔓延度呈增加的趋势,而分离度、多样性、均匀度呈降低的趋势。

Based on the data of land use in 2005 and 2015, the dynamic evolution of land use landscape pattern in Ganjingzi area was studied by GIS technology and landscape pattern index. The results show that： （1） Ganjingzi area of various types of land changes significantly. Other agricultural land and construction land to increase the largest, natural reserves, the park to reduce the rate of large. （2） The number of patches, patch density and contagion of Ganjingzi area increased, while the landscape division index, Shannon＇s diversity index and shannon＇s evenness index decreased gradually.
