摘 要: 在遥感与地理信息系统的支持下,通过解译1991年、2002年、2007年3期Landsat5-TM影像,分析了武汉地区从1991年到2007年土地利用和景观格局的变化情况。结果表明,16年间研究区内景观格局发生了很大变化;农业用地面积、人工建筑用地面积在不断增加,而水域面积和林地面积相对减少;研究区景观的破碎化程度降低,景观多样性水平下降,景观异质性减少;引起变化的主要原因为城市化的快速发展。 The change of land use and landscape pattern from 1991 to 2007 in Wuhan city was discussed based on Landsat5-TM data in 1991,2002,and 2007 with the support of GIS.Results showed that the landscape pattern in Wuhan city had been changed a lot during the last 16 years.The area of agricultural land and building land increased constantly,while those of water and forest land reduced.The landscape pattern could be characterized by gradually decreasing of landscape fragmentation degree,landscape diversity and landscape heterogeneity.The main reasons which led to the change in landscape pattern were the development of urbanization.
