摘　　要：基于2001、2011和2018年三期Landsat遥感影像解译的郴州市苏仙区景观类型分布图,借助ArcGIS和Fragstats软件,分析研究区的景观类型结构、景观动态度、景观面积转移矩阵和景观格局指数变化。运用Clue-s和SPSS软件,通过Logistic回归模型分析研究区17a间驱动力因子。结果表明:(1)2001—2018年苏仙区景观类型结构变化显著,林地一直是苏仙区主要的景观类型,占比超过50%;(2)由景观动态度变化可知,在17a间建设用地的变化速度最快,并处于加速增快的趋势,其次为草地、未利用地和耕地;(3)从景观类型水平上看,林地、草地、耕地和建设用地的景观形状指数增大,说明其受到人类活动的干扰,边界复杂程度上升;(4)从景观水平上可知,苏仙区景观结构维持了较好的多样性,各斑块类型面积比重趋于平衡,景观的破碎化程度逐渐增大;(5)由景观类型面积转移矩阵可知,在保证基本农田保护红线的基础上,农业用地大面积转化为建设用地,建设用地的不断扩张将逐步成为该区主要景观;(6)由驱动因子分析可知,自然因素影响林地、草地、耕地、水域较多,社会经济因素影响建设用地和未利用地较多。Based on the Landsat remote sensing images for the landscape distribution of Suxian district of Chenzhou City in 2001,2011 and 2018,ArcGIS and Fragstats were used to analyze the changes in the landscape type structure,the landscape dynamic attitude,the landscape area transfer matrix and the landscape pattern index in the studied area.Through using Clue-s and SPSS,the driving force factors in 17 years(17a)of this district were analyzed by the logistic regression model.The results were stated as follows:(1)In 2001-2018,the landscape type structure of Suxian district had changed dramatically,and the forest was always the major landscape type in Suxian District,occupying a ratio higher than 50%;(2)According to the landscape dynamic change in 17a,the change of construction lands was the quickest and was still accelerating,followed by the grasslands,the unused land and the cultivated land;(3)In terms of landscape type,the landscape shape index of the forest,the grassland,the cultivated land and the construction land increased,which means that the boundary complexity was increased due to the affection of human activities;(4)In terms of landscape level,the landscape structure of Suxian district maintained a good diversity,the area ratio of each sector was coming closer to balance,and the landscape fragmentation degree was increasing;(5)According to transition matrix of landscape area,within the red-line for basic farmland protection,lots of agricultural lands had been converted into construction lands;the continuous expansion of construction lands would gradually become the major landscape of this district;(6)According to driving force factor analysis,natural factors gave more impact on forest,grasslands,cultivated lands and water area;social and economic factors gave more impact on construction lands and unused lands.This research has directive significance to urban landscape ecological planning and future construction of Suxian District,and it also provides important reference for urbanization development and urban lan
