摘　　要：以洛阳市中心城区为研究对象,采用景观指数和梯度分析相结合的方法,以近15年城区遥感影像数据为依据,以洛河为中心,采用GIS软件进行图像处理,分别向洛河南北两岸构建3 km间隔缓冲带,分析洛阳市中心城区景观格局时空动态变化和梯度变化特征。结果表明,近15年来在城市化的不断推进下,各类型斑块面积占比有显著变化,景观格局结构不断转变;各类型斑块的时空梯度特征差异明显,洛河南北两岸在不同的城市建设力度下表现出不同的水平特点;景观格局逐渐向破碎化、异质化方向发展,城市化过程和人为干扰是影响景观格局梯度变化特征差异的重要因素。Taking the central urban area of Luoyang City as the research object,the method of combining landscape index and gradient analysis was adopted.Based on the remote sensing image data of the urban area in recent 15 years,the Luohe River was taken as the center,and GIS software was used for image processing,to build a 3 km interval buffer zone to the north and south sides of the Luohe River,and analyze the spatial-temporal dynamic changes and gradient changes of the landscape pattern in the central urban area of Luoyang.The results showed that with the continuous advancement of urbanization in recent 15 years,the proportion of various types of patch areas had significantly changed,and the landscape pattern structure was also constantly changing;the spatial-temporal gradient characteristics of various types of patches differed significantly,and the north and south sides of the Luohe River exhibited different levels of characteristics under different urban construction efforts;the landscape pattern was gradually developing towards fragmentation and heterogeneity,and the process of urbanization and human interference were important factors affecting the differences in gradient changes of landscape pattern.
