摘　　要：基于昆明市2005年、2010年、2020年遥感影像和土地利用现状数据,利用遥感(RS)、地理信息系统(GIS)技术,分析呈贡大学城土地利用景观的空间格局及其变化特征。结果表明:在呈贡大学城建设期间,研究区域由农村田园景观变为典型的城市园林景观。耕地大幅减少并转向建设用地,且土地用途之间的空间关系趋向复杂。虽然耕地形式趋于简单化,但建设用地形式愈加复杂化,建设用地用途之间的空间关系也在恶化,土地利用类型空间连通性变差。整体景观的破碎化程度增强,异质化程度逐渐增大,形成了具有多种类型的密集格局。The spatial pattern of land use landscape and its changing characteristics in Chenggong University Town were analyzed by using RS and GIS technologies,based on the remote sensing images and land use data of Kunming in 2005,2010,and 2020.The results showed that the study area changed from a rural landscape to a typical urban garden landscape during the construction of Chenggong University Town.Arable land had been substantially reduced and shifted to construction land,and the spatial relationship between land uses had become more complex.Although the form of arable land tended to become simpler,the form of construction land was becoming more complex,the spatial relationship between construction land uses was also deteriorating,and the spatial connectivity of land use types deteriorated.The overall landscape became more fragmented and heterogeneous,resulting in a dense pattern with various types.
