徐州主城区景观格局变化分析

         

摘要

Based on the Landsat-5 images of 2010 and Landsat-8 images of 2016 as spatial data, under the supporting of Arcgis and Fragstats software, we analyzed characteristics of urban landscape pattern during these years in Xuzhou.Using Fragstats to analyze the landscape indices of these two periods, the results show that the cultivated land area within the main urban area of Xuzhou has a significant decrease and the landscape of the cultivated land is fragmentation.The urban construction land increased and was dispersed to other landscape patterns.The forest land increased slightly and the shapes changed complicated.The grass land didn't changed obviously during recent years.The water land's three landscape indices all increased, and the landscape stability has been improved.The landscape′s PD, SHDI, LSI increased but other landscape indices declined indicating the more fragile overall urban landscape than before.%选择2010年的Landsat-5影像和2016年的Landsat-8影像,通过Arcgis目视解译和地面核查,建立了徐州市主城区这两个时期的土地利用类型数据,利用Fragstats对这两个时期的景观指数进行了分析计算.结果表明:徐州主城区范围内的耕地面积有较为显著的减少,耕地景观破碎化.建设用地面积增加明显,分散到其他土地类型的间隙中.林地面积略有增加,并且形状变得复杂.草地的3个指数基本没有变化,说明草地斑块在最近几年来没有太多变化.水体的3个景观指数都有所上升,景观稳定性提高.2016年徐州市主城区景观的PD、SHDI、LSI指数上升,其他指数下降,说明最近几年徐州主城区景观整体更加地破碎化了.
