摘要:
 植被覆盖度是表征植被生长状态、生态系统变化的重要参数，对景观格局变化、城乡发展研究有重要意义。为揭示社会经济活动对植被覆盖度时空分布的影响，基于局部加权回归法构建时间序列曲线，以丽江坝区1987、1991、1994、2010、2018年5期Landsat遥感影像为数据源，采用回归趋势与同心圆空间梯度模型获得植被覆盖度时空变化特征，并运用偏最小二乘回归模型进行驱动力分析。结果表明，1987-2018年，研究区的主城区内和村落周边的植被覆盖发生了明显退化；主城区内植被覆盖的地区破碎化程度高于郊区，主城区内中低、中等覆盖度地区的斑块形状逐渐复杂、景观连接度增加，中高、高植被覆盖度地区斑块形状越发规则，高植被覆盖度地区的连接度逐渐降低；主城区及其周边的中低、中等植被覆盖度的斑块分布逐渐密集，中高、高覆盖度的斑块聚集度逐渐降低；日照时数、人口密度、公路客运量、财政收入是丽江坝区植被覆盖度变化的主要驱动力。
Abstract:
 Vegetation coverage is an important parameter to characterize plant growth and ecosystem change,which is of great significance to the study of landscape pattern change and urban-rural development.To reveal the impact of socio-economic activities on the vegetation coverage spatio-temporal change,this study constructed a time series curve based on the locally weighted regression,and acquired 5 Landsat remote sensing images in 1987,1991,1994,2010 and 2018 of Lijiang Dam area as the data sources.The spatio-temporal variation characteristics of fractional vegetation cover (FVC) were obtained by using the regression trend and concentric spatial gradient analysis model,and the partial least squares regression was used to analyze the spatial and temporal variation and driving forces of FVC in the study area.The results showed that the vegetation coverage of inside main urban area and around the village degenerated substantially in the study area during 1987 to 2018.The fragmentation degree of vegetation coverage area in the main urban area was higher than the suburbs.The patch shape of the low-medium and medium vegetation coverage areas in the main urban area was complicated gradually and the landscape connectivity increased gradually in the urban area.The patch shape of the high-medium and high vegetation coverage areas was more regular,and the landscape connectivity of the high vegetation coverage area reduced gradually.The patch distributions of low-medium,medium vegetation coverage of the main urban area and suburban areas were concentrated while the patch aggregation of high-medium and high coverage reduced gradually.The major driving factors were the sunshine duration,population density,road passenger capacity and financial revenue for vegetation coverage change in the Lijiang Dam area.
