Abstract:

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.

Key words: natural reserve, forest vegetation type, forest health, index system, evaluation
