摘要
利用福建将乐林场1996年和2007年2期森林资源规划设计调查数据和样地调查数据,根据杉木人工林结构与功能关系构建了耦合关系模型,评价杉木人工林各小班的主导功能及其变化。结果表明:1996年杉木人工林的主导功能为木材生产、风景游憩和涵养水源的小班比例分别为33.15%、33.70%、33.15%;2007年杉木人工林的主导功能为木材生产、风景游憩和涵养水源的小班比例分别为37.83%、34.27%、27.90%。1996年至2007年10年间以木材生产和风景游憩为主导功能的小班数量分别增加了4.68%和0.57%,而以涵养水源为主导功能的小班数量减少了5.25%。评价结果符合林场实际情况。研究结果旨在为将乐林场杉木人工林多功能经营提供了理论和方法依据。
Using two sets figures of forestry resource survey in Jiangle forest farm in 1996 and 2007 and sampling data, the dominant function and the dynamic change of Chinese fir plantation sublots were evaluated by founding the coupling model based on the relationship between structure and function of Chinese fir plantation. The results show that：Chinese fir plantation sublots took timber production, scenic recreation and water conservation as the dominant function accounted for 33.15%、33.70%、33.15% respectively in 1996;Chinese fir plantation sublots took timber production,scenic recreation and water conservation as the dominant function accounted for 37.83%、34.27%、27.90% respectively in 2007; From 1996 to 2007,the number of sublots which took timber production,scenic recreation as the dominant function were increased by 4.68% and 0.57%, the number of sublots which took water conservation as the dominant function were decreased by 5.25%.The evaluation results agree well with the actual situation of Jiangle forest farm. The results of th e study will provide theory and basis for multi-function management of Chinese fir plantation in Jiangle forest farm.
