杉阔混交人工林
1.
Through investigating and analyzing the change of forest land vegetation of artificial mixed forests of Cunninghamia lanceolata and broad-leaf trees before and after clear cutting,the results show that some species invaded into the clear cutting site and other species declined after clear cutting.
通过对皆伐作业前后杉阔混交人工林林地植被变化的调查分析,结果表明:皆伐后一部分植物消失(衰退种)、一部分植物增加(侵入种),但优势植物基本保留下来(保留种),这主要是由于迹地清理方式采用带堆法的缘故。
