Abstract

The Poverty Alleviation Relocation (PAR) policy is widely regarded as an effective approach for breaking the cycle of ecological vulnerability and poverty. However, quantitative research on the ecological restoration effectiveness of PAR lacks sufficient experimental data support. This study focuses on the karst region and employs analysis methods such as volume-derived biomass and correlation analysis to evaluate the impact of PAR on carbon storage in forest ecosystems using on-site experimental data. The objective is to enhance and broaden the research framework for assessing PAR’s ecological restoration effectiveness. The findings reveal that, compared to the pre-PAR implementation period in 2015, the study area experienced an 8.16% increase in forest land area and a 6.57% increase in carbon storage after six years of PAR implementation in 2021. Following PAR implementation, carbon storage in the stone desertification area surged by 14.31%, indicating a significant correlation between PAR households and carbon storage variables. In the karst area, carbon storage increased by 4.34%, exhibiting a significant correlation between the two variables. Conversely, in the non-karst area, carbon storage rose by 5.01%, but no significant correlation was observed between the variables. Furthermore, post-PAR implementation, there is a discernible trend of stronger carbon storage enhancement with increasing distance from the relocated PAR households.

通过碳储存分析评估扶贫搬迁的生态恢复效果：喀斯特地区的启示

扶贫搬迁（PAR）政策被广泛认为是打破生态脆弱性和贫困循环的有效方法。然而，有关 PAR 生态恢复效果的定量研究缺乏足够的实验数据支持。本研究以岩溶地区为研究对象，采用生物量体积衍生分析和相关性分析等分析方法，利用现场实验数据评估 PAR 对森林生态系统碳储存的影响。目的是加强和拓宽评估 PAR 生态恢复效果的研究框架。研究结果表明，与 2015 年 PAR 实施前相比，2021 年 PAR 实施六年后，研究区域的林地面积增加了 8.16%，碳储量增加了 6.57%。实施 PAR 后，石漠化地区的碳储量激增了 14.31%，表明 PAR 户与碳储量变量之间存在显著相关性。在岩溶地区，碳储量增加了 4.34%，这两个变量之间存在显著的相关性。相反，在非喀斯特地区，碳储量增加了 5.01%，但两个变量之间没有发现明显的相关性。此外，PAR 实施后，随着与 PAR 搬迁户距离的增加，碳储存量有明显增加的趋势。
