摘要
根据海南省昌江县森林资源调查数据,在GIS支持下应用Fragstats和景观生态学理论,将海南省昌江县森林资源划分为12个森林景观类型,建立栅格化数据库,选取15个关键景观格局指数进行分析。研究表明昌江县天然林和各景观类型聚集度高,空间异质性强,破碎化程度小,景观多样性较为丰富,景观指数间表现出较高的相关性,生态总体质量好,有利于维系生物多样性和生态系统功能。
Based on the data from forest resource survey in Changjiang county,by using Fragstats under support of ArcGIS and landscape ecology theory, forest land has been classified into 11 classes. A raster has been build, and 15 key landscape pattern indexes have been computed. The results show that the nature forest and other landscape classes has a high aggregation, spatial heterogeneity, low fragmentation and contagion index.
