摘要
基于华安县2008年森林资源二类调查成果,将林地景观分为11个景观类型,在ArcGIS 10.2和Fragstats4.2软件支持下,利用景观水平指数和景观类型水平指数对林地景观格局进行分析。结果表明:马尾松林、阔叶林、杉木林、经济林、桉树林、竹林景观在全县林地景观中占优势,整体上林地景观异质性程度较高,多样性丰富,均匀度较高,呈现一定的破碎状态。杉木林破碎化程度高,与外界物质能量交换程度也较高,而整体上11个景观类型聚集度水平均较高。
Based on forest resource survey results in Huaan County in Fujian Province in 2008,11 forest landscape types were divided,and these forest landscape patterns were analyzed by using landscape level index and landscape type level index with support of ArcGIS 10. 2 and Fragstats 4. 2 software. The results showed that the landscapes of Pinus massoniana forest,broad-leaved forest,Cunninghamia lanceolata forest,cash forest,Eucalyptus forest,bamboo forest were the dominant forest landscape of Huaan County. In general,forest landscape heterogeneity in this county was high,with rich landscape diversity,high landscape evenness with certain broken landscape state. Forest landscape of Cunninghamia lanceolata had higher fragmentation degree,and the exchange degree of material and energy with the outside was also higher. The landscape type aggregation levels of above 11 types were high on the whole.
