摘要
利用贵州省福泉市2015、2019年两期森林资源调查数据,将研究区内林地景观类型分为:乔木林、竹林、疏林地、灌木林地、宜林地及其他林地6类景观类型,并借助GIS、Fragstats等分析工具及景观生态学原理,分析了福泉市2015~2019年林地景观斑块特征演变情况。结果表明:福泉市林地面积有所增加,乔木林和灌木林是福泉市的主要景观类型;研究区除疏林地、其他林地外,其余林地景观类型的LSI指数均有所上升,形状趋于复杂;PAFRAC除疏林地保持不变外,其余各林地景观类型的PAFRAC均有所下降,形状趋于规律;PD除其他林地保持不变外,其余各林地景观类型的PD均有所上升,林地受干扰程度有所增加。
Based on the forest resource survey data of 2015 and 2019 in Fuquan City,Guizhou Province,the forest types in the study area were divided into six landscape types,arbor forest,bamboo forest,open forest,shrub forest,suitable forest and other forests.With the help of GIS,Fragstats landscape analysis tools and the principles of landscape ecology,the evolution of forest landscape patch characteristics in Fuquan City from 2015 to 2019 was analyzed.The results show that the area of forest land in Fuquan City has increased,and arbor forest and shrub forest are the main landscape types in Fuquan City.Except open forest land and other forest lands in the study area,LSI index of other forest land landscape types all increased,and their shapes tended to be complex.PAFRAC of all woodland landscape types decreased and the shape of PAFRAC tended to be regular except for the open forests.Except for other forests,PD of other forest land landscape types all increased,and the degree of disturbance of forest land increased.
