森林自然保护区保护效果评价方法:挑战与进展

建立自然保护区是保护生物多样性的最有效的保护措施之一,但如何评估自然保护区保护效果一直是自然保护研究的难点。本文针对热带森林自然保护区保护效果评价方法进行综述,分析热带森林自然保护区保护效果评价面临的挑战:空间不可比、时间不可比;明确了热带森林自然保护区保护效果评价可比性建立的基本模式:确定森林退化指标,选择协变量,平衡协变量,选择对比方式,判断并去除空间溢出的影响范围;回顾了自然保护区保护效果评估常用统计方法:回归评估法和匹配评估法。为了加强热带森林自然保护区保护效果评估,在今后评估方法选择过程中建议:强化时空对比;强化多学科交叉方法的应用;强调多维度评估指标的选择和应用。

Conservation Effect Assessment Methods of Forest Nature Reserves: Challenges and Research Progress

One of the most common conservation strategies in the protection of biodiversity is the establishment of protected areas (PAs), but how to evaluate protected areas'' protection effect is always the difficulty of natural conservation research. We summarize the protective effect assessment methods of tropical forest PAs, and analyze the challenges of tropical forest PAs'' protection effect evaluation:space and time are not comparable; We clarify the basic pattern of comparability build for tropical forest PAs'' protection effect evaluation:determine the forest degradation index, select and balance covariates, choice comparative ways, judge and remove the influence of space spillover; Then we review the statistical methods:regression and matching methods. In order to strengthen the evaluation of tropical forest PAs'' protection effect, we suggest that we should strengthen the spatial-temporal contrast and the application of multidisciplinary methods and emphasize the selection and application of multi dimension evaluation index in the future.
