摘要
以海南省岛东林场木麻黄退化人工林补植乡土树种和珍贵树种为研究对象,提出近自然化改造经营模式。在岛东林场木麻黄林下补植乡土树种和珍贵树种的3种改造模式进行比较。结果表明,以模式2林木生长的效果较好,能够有效地改善林分的水平和垂直结构,调节林冠下光环境,增大林冠下散射光比例,为下层植被生长提供有效光照条件;增加树种多样性和森林的近自然程度,为退化森林恢复经营提供模式和范例。
Replanting native tree species and rare tree species in at by taking Casuarina degradation plantation forests Daodong Forest Farm of Hainan as the research object, near-nature transformation modes were put forward. The three kinds of transformation modes of repair planting native and rare tree species in Casuarina plantation forests were compared. The results showed that the growth of the forests of pattern 2 was the best, This pattern could effectivity improve spatial structure of the forest stand, regulate light environment under the canopy, increase scattering light proportion under the canopy, provide effective illumination condition for the lower vegetation growth.At the same time, it could increase the degree of species diversity and forest near nature, provide a scientific basis for the development of economic.
