摘要:

科学准确地评估保护区的保护成效对于减少生物多样性丧失具有重要意义, 然而若对保护区内外的环境差异及溢出/泄漏效应考虑不足, 将导致评估结果出现偏差。本文以河南伏牛山地区3处国家级自然保护区(伏牛山、宝天曼、南阳恐龙蛋化石群)为研究对象, 使用倾向得分匹配模型(propensity score matching model)和平均处理效应(average treatment effects)对3处保护区2000-2020年净初级生产力(net primary production, NPP)和抵御人类扰动的保护成效及溢出/泄漏效应进行评估, 并借助单因素方差分析探讨其影响因素。结果表明: (1)在NPP保护方面, 2000-2010年伏牛山和南阳保护区成效显著, 分别出现泄漏和溢出效应, 2011-2020年伏牛山和宝天曼保护区成效差并出现泄漏效应。(2)在抵御人类扰动方面, 2000-2010年伏牛山保护区成效显著, 南阳保护区成效较差, 2011-2020年3处保护区成效均较好且出现溢出效应。(3) NPP本底值低, 以及气温和降水量高时, NPP保护成效好且易于发生溢出效应, 人口密度低和GDP水平高时, 抵御人类扰动的成效好且易于发生溢出效应, 反之成效差且易于发生泄漏效应。以上结果表明保护成效和溢出/泄漏效应在伏牛山地区存在阶段性变化与保护区分异, 自然和社会经济因素对其有显著影响。倾向得分匹配和溢出/泄漏效应评估方法为保护区整体评估提供了新的技术思路。

Abstract

Aims: The scientific and accurate assessment of the protection effectiveness of nature reserves is of great significance for reducing biodiversity loss. However, inadequate consideration of environmental differences inside and outside nature reserves and spillover/leakage effects will lead to biased assessment results. This paper aims to evaluate the protection effectiveness and spillover/leakage effects of the national nature reserve group of Funiu Mountain area in Henan Province and their influencing factors.
Method: In this study, three national nature reserves including Funiu Mountain National Nature Reserve (NNR), Baotianman NNR, and Nanyang Dinosaur Eggs Fossil Cluster NNR in Funiu Mountain area were selected. The propensity score matching model and average treatment effects were used to evaluate the effectiveness of protection and spillover/leakage effects of net primary production (NPP) and resisting human disturbance. The one-way analysis of variance was used to identify and discuss the influencing factors for these.
Results: (1) In terms of NPP, the protection effectiveness of Funiu Mountain NNR and Nanyang Dinosaur Eggs Fossil Cluster NNR was significant from 2000 to 2010, with leakage and spillover effects occurring, respectively. From 2011 to 2020, the protection effectiveness of Funiu Mountain NNR and Baotianman NNR was poor, and leakage effects occurred. (2) In terms of resisting human disturbance, the effectiveness of Funiu Mountain NNR from 2000 to 2010 was good. However, the effectiveness of the Nanyang Dinosaur Eggs Fossil Cluster NNR was poor. From 2011 to 2020, the three NNRs showed significant reduction in human disturbance, and spillover effects occurred. (3) When the NPP background value was low and the temperature and precipitation were high, the nature reserves had better NPP protection effectiveness and were prone to spillover effect; when the population density was low and the GDP level was high, the nature reserves had better effectiveness in resisting human disturbance and were prone to spillover effect, whereas the effectiveness was poor and prone to leakage effect.
Conclusion: The protection effectiveness and spillover/leakage effects differ among different natural reserves in different periods in the Funiu Mountain area, and natural and socio-economic factors significantly impact this. The propensity score matching model and spillover/leakage effects provide a new technical idea for the overall protection assessment of the nature reserves.
