Abstract

Establishing protected areas has been a longstanding strategy to conserve forests. Net Primary Productivity (NPP) offers a reflection of ecosystem quality and vegetation vitality compared to traditional spatial indicators, making it a valuable metric for evaluating conservation outcomes in protected areas. Additionally, there is a lack of knowledge about the concurrent influence of in situ conservation and pertinent policies on forest conservation. Through Propensity Score Matching (PSM) and the Difference-in-Difference (DID) model, we evaluated the conservation outcomes of NPP within protected areas and identified different policies’ impacts. Wuyi Mountain in China, known for its rich forest resources, was selected as the study area. The results revealed: (1) NPP within all protected areas fluctuated within a stable range from 1985 to 2021, with some exhibiting a significant upward trend; (2) A total of 62.5 % of protected areas demonstrated a positive effect on forest NPP. There is a 72 % effective conservation rate for nature reserves, one type of protected area in China, making them the most effectively protected in Wuyi Mountain; (3) In 50 % of the cases, the policies resulted in positive outcomes. The impact of policies on forest NPP varies across different types of protected areas; (4) Only 16.67 % of policy scenarios demonstrated a concurrent positive effect from both protected areas and conservation policies. By analyzing the impact of protected area establishment and conservation policy implementation on NPP, our research can offer valuable insights for policymakers aiming to enhance forest conservation in mountain areas.

建立保护区和实施区域政策都能促进森林净生产力吗？基于 PSM-DID 的中国武夷山证据

建立保护区是保护森林的一项长期战略。与传统的空间指标相比，净初级生产力（NPP）能够反映生态系统的质量和植被的活力，因此成为评估保护区保护成果的重要指标。此外，人们对原地保护和相关政策同时对森林保护的影响还缺乏了解。通过倾向得分匹配法（PSM）和差分法（DID）模型，我们评估了保护区内NPP的保护成果，并确定了不同政策的影响。研究选取了以森林资源丰富著称的中国武夷山作为研究区域。研究结果表明：（1）从 1985 年到 2021 年，所有保护区内的净生产力都在一个稳定的范围内波动，其中一些保护区的净生产力呈显著上升趋势；（2）共有 62.5% 的保护区对森林净生产力产生了积极影响。自然保护区（中国保护区的一种）的有效保护率为 72%，是武夷山保护效果最好的保护区；（3）在 50% 的案例中，政策产生了积极的结果。在不同类型的保护区中，政策对森林净生产力的影响各不相同；（4）只有 16.67% 的政策情景同时显示了保护区和保护政策的积极影响。通过分析建立保护区和实施保护政策对净生产力的影响，我们的研究可为旨在加强山区森林保护的政策制定者提供宝贵的见解。
