以2018年5月20日的上杭县城区航空影像图为信息源,2017版上杭县城区修测地形图为基础数据,ArcGIS10.2为平台,结合GPS定位外业调查数据,在Fragstats4.2上计算景观格局指数,对上杭县城市景观格局进行分析,归纳出上杭县城市景观格局的特点。结果表明,上杭县城市规划中存在的问题是主城区阻塞了重要动物的迁徙通道;公用设施景观建设跟不上城市发展的需要;城市周边大量农业景观未良好利用;"城中村"布局散乱。由此提出了景观格局优化对策:优化布局结构;控制人工景观面积,增加城市绿地;发展农事旅游;改造"城中村";整合小型工业企业。该研究可为上杭县城市景观生态规划、城市建设提供参考。

Taking the aerial images of the urban area of Shanghang County on May 20,2018 as information sources,on the basis of revised terrain map of the county urban area of 2017,the urban landscape pattern characteristics were summarized by using ArcGIS10.2 as platform,combining with GPS field survey data and the calculation on Fragstats4.2 landscape pattern index.Problems existed were pointed out:the downtown blocked the important animal migration channel; the landscape construction of public facilities could not keep up with the need of urban development; a large number of agricultural landscapes ar...
