摘要
千岛湖国家森林公园林地中约有3/4(2万hm2)为马尾松次生林,森林景观单一,生态功能脆弱。1996年5~7月在小金山林区进行了砍松留阔间伐试验,经过6a多的观察,马尾松纯林已逐步向针阔混交林过渡,且有向原始常绿阔叶林演替的趋势。
Three quarters of Thousand-isles Lake Na t ional Forest Park (20 000 hm2) managed by Xin'anjiang Development Controllin g Corporation in Chun'an in Zhejiang Province cover Pinus massoniana second ary fores t,which can't meet the need of ecological and social benefit due to the monotono us landscaping and no tree diversity.In order to research into transformation te chno logy of Pinus massoniana secondary forest phase,interval cutting experiment was made in Xiaojinshan Pinus massoniana forest district from May to July o f 1 996.After six years of observation,the result indicated that interval cutting ha s promoted the transition from pure Pinus massoniana forest to mixed forest of n eedle and broad-leaved trees,and the evolvement from the mixed forest with Pi nus massoniana as its basis to evergreen broad-leaved trees,thereby improved ecological condition,increased economic profit,added new sights eeing near Thousand-isle s Lake National Forest Park.
