摘　　要：以松花江流域(哈尔滨段)为研究区域,基于2010和2015年Landsat TM/ETM遥感影像进行景观类型提取。对两期影像进行网格划分,根据景观敏感度计算公式对网格进行相关景观指数提取,计算网格敏感度,并进行克里格插值,形成景观敏感度及变化连续空间分布。研究结果表明:从2010年到2015年,研究区域整体景观敏感度从26.888变为21.239;景观敏感度变化较多的区域位于中部偏东区域及东部边缘地区,是因为伴随着城镇化的进程易损度较高的耕地不断减少,易损度较低的居民地城镇用地随之增加;随着规划用地日趋合理化,易损度高的未利用地呈现快速减少的态势。In this paper,the Songhua River Basin(Harbin Section)is taken as the study area,based on the 2010 and 2015 Landsat TM/ETM remote sensing images for landscape type extraction.The two phases of the image are meshed,and the relevant landscape index is extracted according to the landscape sensitivity calculation formula.Kriging interpolation is used to interpolate the landscape pattern sensitivity and change value of the two-phase grid to form the landscape pattern sensitivity and change continuous spatial distribution.The results show:from 2010 to 2015,the overall sensitivity of landscape pattern in the study area changed from 26.888 to 21.239.Landscape sensitivity changes more in the eastern and eastern edge of the central region,due to the process of urbanization vulnerable to higher arable land continues to decrease,vulnerable to lower residential land increased urban land use;with the rationalization of planning land,vulnerable to high unused land showed a rapid decline in the state potential.
