徂徕山生态公益林健康评价及经营决策

FOREST HEALTH ASSESSMENT AND MANAGMENT DECISION MAKING PARK OF ECOLOGICAL FOREST IN CULAI MOUNTAIN FOREST

生态公益林作为生态建设的主体现已成为国内外关注的重点,对其进行健康评价和经营决策研究十分必要。本文根据徂徕山生态公益林的调查及分析数据,选用适合徂徕山生态公益林健康评价的指标,用主成分分析法对其健康状况进行综合评价,评价结果为:赤杨纯林的健康等级为Ⅰ;刺槐纯林、麻栎纯林、油松/刺槐混交林的健康等级为Ⅱ;赤松纯林、油松纯林、黑松纯林、日本落叶松纯林的健康等级为Ⅲ;油松/侧柏混交林的健康等级为Ⅳ。根据评价结果及样地调查,对不同健康等级的林分从调节密度、增强间伐力度、提高生物多样性、加强基础设施建设等方面提出保护与发展的经营决策,充分发挥生态公益林的效益,保证林分的健康稳定。

As the main body of ecological construction,ecological forest has become the focus both in China and in the world,and forest health condition assessment and forest resources management research is extremely essential.This paper is evaluating the ecological forest of Culai mountain comprehensively according to the surveying data,with the best evaluating indictors for Culai mountain,and the methods of principal component analysis.The results showed： The health-degree of Alnus japonica pure forest is Ⅰ;The health-degree of Robinia pseudoacacial.pure forest,Quercus acutissima pure forest,Pinus tabulaeformis/Robinia pseudoacacial.mixed forest are Ⅱ;The health-degree of Pinus densiflora pure forest,Pinus tabulaeformis pure forest,Pinus thunbergii pure forest and Larix kaempferi pure forest are Ⅲ;The health-degrees of Pinus tabulaeformis/Platycladus orientalis mixed forest is Ⅳ.Management decisions,such as density regulation,the intensity of intermediate cutting,and the biodiversity improving,will be proposed according to the evaluation results and sample-plot surveying for the forest protection and development,to fully expert the benefits of ecological forest and to grantee the forest＇s healthy and stable.
