茂兰森林景观多样性分析(英文)

Analysis of Landscape Diversities in Maolan Forests

以茂兰自然保护区的森林景观为研究对象,从不同层次将保护区分为2个级别,第1级包括核心区、缓冲区、试验区;第2级包括9种类型的景观斑块。借助地理信息系统(GIS)手段,对其森林景观特征及多样性进行研究。结果表明,茂兰自然保护区森林景观整体保护良好,但因自然干扰及人类活动增加等原因,灌木林和非林地景观类型占较重要的位置。保护区的3个功能区中,核心区的景观组分中以大斑块为主,破碎化程度低;缓冲区虽有人类活动增强的趋势,但因其森林面积广阔,且保护良好,景观格向破碎化转变还不明显;试验区景观的破碎化程度最高,这一切都说明了各功能区因受人为干扰强度的不同,从而形成了景观特征的差异。

With Maolan Nature Reserve as an example, its forest landscape characteristics and diversity were studied by utilizing GIS. The results showed that the overall forest landscape in Maolan Nature Reserve was quite good, but with the increasing natural interferences and human activities, shrub forests and non-woodland landscape types have been multiplied; among the 3 functional zones of the Nature Reserve, landscape fragmentation degree is low in core zone and buffer zone, but high in experimental zone.
