目前，全球剩余的森林面积中有相当大一部分位于热带国家。减少该地区的森林砍伐对于帮助减缓气候变化非常重要。需要采取有效的森林养护办法来减少这些国家的森林砍伐和退化。本文利用柬埔寨的国家尺度数据，对社区森林和保护区的森林保护效果进行了调查。除了这两种森林保护方法，我们还评估了与保护区相似但由不同部门管理的保护林的有效性。我们应用处理加权逆概率和倾向得分最小化混杂效应，比较了三种森林保护方法下的地区和非保护区2006 - 2016年的森林砍伐情况。结果表明：群落林、保护区和保护林的毁林率明显低于非保护林；在三种森林保护方法中，保护林是最有效的，社区森林是最无效的。我们的结论是，我们评估的所有政策对森林保护都是有效的，但有效性因方法而异。我们的研究结果还表明，管理给定方法的权威在其有效性中起着重要作用。
Considerable proportions of the remaining global forest areas are currently harboured in tropical countries. Reducing deforestation in this region is important to help mitigate climate change. Effective forest conservation approach is needed to reduce deforestation and degradation in these countries. Here, we investigated the forest conservation effect of community forests and protected areas using country scale data in Cambodia. In addition to these two forest conservation approaches, we also evaluated the effectiveness of protected forests, which are similar to protected areas but managed by different authorities. We compared deforestation between 2006 and 2016 in areas under the three forest conservation approaches and a non-conserved area by applying the inverse probability of treatment weighting with the propensity score minimizing confounding effects. The results showed that community forest, protected areas, and protected forest significantly decreased deforestation compared with non-conserved forests. Out of the three forest conservation approaches, protected forest was the most effective and community forest was the least effective. We conclude that all of the policies we evaluated are effective for forest conservation but the effectiveness varies depending on the approach. Our findings also suggest that the authority managing the given approach plays an important part in its effectiveness.
