纳板河流域国家级自然保护区主要森林植被类型健康评价研究

本研究以纳板河自然保护区季风常绿阔叶林、落叶阔叶林、热带季雨林、热带山地雨林等4种主要植被类型为研究对象,采用主成分分析法从5大类18个指标中筛选12个指标作为主要植被类型森林健康评价指标;采用德尔菲专家打分法与层次分析法,确定每个指标的权重,并通过森林健康评价指数法对保护区主要植被类型487个小班的森林健康进行评价。结果表明：优质及健康的森林小班有405个,占总面积的77.79%;亚健康及不健康的森林小班有82个,占总面积的22.21%。主要植被类型健康状态整体呈优良,但受社区活动的影响,靠近农田村寨的植被类型健康等级低,需要对其采取一定的措施方能减缓不利局面的恶化,实现人与自然和谐相处的可持续发展目标。

Health Evaluation of Main Forest Vegetation Types in Naban River Nature Reserve

This research took four main vegetation types of the monsoon evergreen broad-leaved forest, deciduous broad-leaved forest, tropical monsoon forest and tropical montane rainforest in the Naban River nature reserve as the research objects, used principal component analysis to select 12 indicators from the 18 indicators in five categories as the forest health assessment indicators for main vegetation types, adopted Delphi expert scoring method and analytic hierarchy process to determine the weight of each index, and assessed forest health of major vegetation types of 487 small classes in reserve through the forest health assessment index method. The results show that there are 405 high quality and healthy forest small classes, accounted for 77.79% of the total area; there are 82 sub-healthy and unhealthy forest small classes, accounted for 22.21% of the total area. The health status of the main vegetation types is good, but due to the influence of community activities, the vegetation types that close to farmlands and villages have low health status, so some measures should be taken to alleviate the deterioration of the adverse situation, realize the sustainable development goal of harmonious coexistence between man and nature.
