摘要:
 基于融江流域2009年森林资源二类调查数字化成果,运用景观生态学原理和景观指数分析方法,通过ArcGIS9.3和Fragstats3.3软件分析了融江流域的I级和II级景观格局特征。选取的景观指数包括斑块总面积(TA)、斑块个数(NP)、类型面积(CA)、平均大小(MPS)、香农多样性(SHDI)、优势度(LDI)、香农均匀度(SHEI)等。研究结果表明,融江流域以有林地和灌木林地组成的森林景观面积比达到74%,保障了流域景观的生态功能;在森林景观中杉木面积比约为49%,同时斑块密度和斑块边缘密度也较大,对景观类型的发育和保持结构功能的稳定都不利。建议将过于单一的杉木纯林向针叶林、针阔混交林结构调整。
