摘要
利用广西岑溪市1999年、2009年两期森林资源规划设计调查数据,借助GIS分析工具及景观生态学原理,分析了间隔期内林地变化及林地景观斑块特征演变情况。研究结果表明:在10年中,岑溪市林地面积有所增加,林地的增加尤其是有林地较大幅度的增加导致了林地整体质量的提升;研究区内林地景观斑块形状指数有所下降,形状趋于规则;斑块分维数有所下降,形状趋于规律;斑块密度指数有所上升,受干扰程度有所增加。全市林地景观格局呈现多样化,破碎化程度增加,林地景观格局的演变主要受人类活动的干扰影响。
By using the data of forest inventory planning and design in Cenxi city in 1999 ＆ 2009, the forestland and landscape patch changes were analyzed with the support of GIS and landscape ecology principle.The results show that in 1999-2009 the total area of the forestland increased slightly, the increasing of forestland, especially greatly increasing of woodland led to the improvement of the whole forestland quality. The value of shape index of the landscape was decreasing, shape trending to be simplified. The heterogeneity of the landscape was decreasing, shape trending to be law. The density index of the landscape was increasing, the degree of interference was increasing. The forestland landscape presented diversification in study area, the fragmentation of forestland landscape was increasing, the mainly reason of change was human activities.
