摘要
根据清镇市的林业需求分析结果,对水源涵养(P_1)、森林旅游(P_2)、水土保持(P_3)、生物多样性保护(P_4)、木材需求(P_5)、调节小气候(P_6)、改善空气质量(P_7)等常绿阔叶林的主要森林功能,利用层次分析法,以经济效益、社会效益和生态效益为评价指标,定量计算各功能类型的综合效益,进行主导功能优选。结果表明,各功能类型的综合效益为:P_3(0.1955)>P_2(0.1727)>P_1(0.1517)>P_4(0.1356)>P_6(0.1154)>P_7(0.1148)>P_5(0.1146),在7种主要的功能类型中以P3即水土保持功能类型的综合效益最佳。因此,清镇市的常绿阔叶林应该以发挥森林的水土保持功能为主,辅以其他功能类型的经营管理模式。研究结果可为区域常绿阔叶林的森林多功能经营提供参考。
According the forestry requirement in Qingzhen,to summarize the function type of evergreen broad-leaved forest, so as to find what is the optimal type. By using analytic hierarchy process method, taking economic benefit, social benefit and ecological benefit as evaluation index to calculate the comprehensive benefits of each function type. The result indicates that the comprehensive benefits is P3(0. 1955) 〉P2(0. 1727) 〉P1(0. 1517) 〉P4(0. 1356) 〉P6(0. 1154) 〉P7 (0. 1148) 〉P5(0. 1146) ,that shows the type P3 is the optimal leading function type. That means the multi-function management of evergreen broad-leaved forest in Qingzhen, the optimal management mode is to emphasis on soil and water conservation, then supplemented by other function. The results can provide the basis for the forest muhi-functional management of the study area.
