摘要
以黑龙江省塔河县为研究区,1998年、2008年和2018年3期Landsat TM影像为数据源,在3S技术的支持下应用Fragstats软件,运用景观生态学方法,对塔河县森林景观格局变化特征进行分析。研究结果显示,塔河县林地与耕地的总面积所占比重多且大部分以大块斑块分布,整体森林景观总面积呈先减少再增加的趋势,面积转移重要表现在林地向耕地、草地的转化。1998~2018年,由于分离度指数呈上升趋势,塔河县景观格局的破碎程度逐渐加剧。在森林景观动态变化分析的基础上,文中提出了塔河县森林保护的建议,为区域生态保护与生态城市建设提供科学借鉴。
Taking Tahe County of Heilongjiang Province as the research area,1998,2008 and the third Landsat TM images of 2018 were used as data sources,Fragstats software was applied with the support of 3S technology,and landscape ecology methods were used to analyze the forest landscape pattern of Tahe County.Change characteristics are analyzed.The research results show that the total area of forest land and cultivated land in Tahe County is large and most of them are distributed in large patches.The total area of the overall forest landscape decreases first and then increases.From 1998 to 2018,the degree of fragmentation of the landscape pattern in Tahe County gradually increased due to the rising trend of the separation index.Based on the analysis of the dynamic changes of the forest landscape,the paper puts forward suggestions for forest protection in Tahe County,which provides scientific reference for regional ecological protection and ecological city construction.
