摘　　要：通过景观格局敏感性、适应性及人口压力指数构建景观格局脆弱性指数,以松花江流域(哈尔滨段)为研究对象,在完成研究区域2005年、2010年和2015年三期景观类型提取的基础上,借助地统计学理论及空间自相关分析方法,对2005-2015年区域景观格局脆弱度的时空变化特征及空间关联格局进行分析。结果表明:1)研究区域景观格局脆弱度整体呈现先增加后减小的变化趋势,脆弱度全局自相关莫兰指数分别0.4761、0.3978和0.4671,表现为较强的正相关,Z-Score值分别为50.21、41.96和49.26,呈聚类模式的空间分布;2)景观脆弱度高-高聚集分布由中东偏南区域向中西部转移,低-低聚集分布区域未发生较大变化,但逐渐表现为深度聚集状态;3)三期景观格局脆弱性空间相关性主要受结构性因素影响,但自2010年人类活动对景观格局的影响程度加深。In this paper,the vulnerability index of the landscape pattern is constructed based on the landscape pattern sensitivity,the landscape pattern adaptability and the population pressure index.We have taken the Harbin Section of the Songhua River Basin as the research target.The study is supported by ENVI5.3,and based on Landsat TM/ETM remote sensing data and non-remote sensing data such as administrative division maps,land use status maps and field survey data.The maximum likelihood method is used to investigate the landscape within three time periods of 2005,2010 and 2015.By applying the geostatistics theory and the software GS+,we have analyzed the statistical characteristics of the landscape pattern vulnerability in the third phase,and determined the rationality of grid division.Spatial and temporal variation characteristics and spatial correlation of the landscape pattern vulnerability were then identified by using the spatial autocorrelation analysis method.Summary of the results are as follows.1)The landscape pattern vulnerability in the Songhua River Basin(Harbin Section)increased first and then decreased from 2005 to 2015.The global Moran index of the landscape pattern vulnerability in this area was 0.4761,0.3978 and 0.4671 for 2005,2010 and 2015,respectively,and the Z-Score was 50.21,41.96 and 49.26 for 2005,2010 and 2015,respectively,showing a strong positive correlation.This suggests that the spatial distribution of the landscape pattern vulnerability was clustering.2)From 2005 to 2015,the high-to-high landscape vulnerability aggregation in this area shifted from the middle-east by south region to the central and western region;while the low-to-low landscape vulnerability aggregation distribution did not change significantly,but gradually showed a state of deep aggregation.3)The spatial correlation of the landscape pattern vulnerability was mainly affected by structural factors,but it was also found that the impact of human activities on the landscape pattern was deepened from 2010 to 2015.The results of
