- 摘要:
- 为研究宁夏海原县生态脆弱性与经济贫困的空间耦合关系,揭示其空间分异特征,基于统计调查数据和遥感数据,结合地理信息技术,以村域为研究单元,通过构建评价指标体系,对海原县生态脆弱性与经济贫困程度、空间耦合关系以及分异规律进行了综合分析。结果表明:海原县生态脆弱性整体处于中等偏高水平,且空间差异较大,空间分布格局具有较强的集聚性特征,生态脆弱性高的地区主要分布在开发强度大、人类活动频繁的河川河谷区以及海拔高、地形起伏大的南部地区; 从贫困程度来看,海原县中度贫困及以上的行政村比例为55.72%,表明研究区整体贫困程度较深,重度贫困和极度贫困集中分布在海拔高、坡度和地形起伏大的南部和西部地区; 从生态与经济耦合关系来看,研究区生态脆弱性与经济贫困耦合协调程度较低,协调同步发展比例为10.71%,失调环境滞后型和失调经济落后型行政村数量最多,且空间分布较为集中,主要集中分布在海原县东部和南部等地区。研究结果可为促进区域生态经济协调可持续发展,实现乡村振兴提供科学参考。
- Abstract:
- In order to study the spatial coupling relationship between ecological vulnerability and economic poverty in Haiyuan County, Ningxia, and to reveal its spatial differentiation characteristics, based on statistical survey data and remote sensing data, geographic information technology, the village was used as a research unit, and an evaluation index system was constructed to analyze Haiyuan County's ecological fragility and economic poverty, spatial coupling relationship and differentiation rule. The results show that the overall ecological vulnerability of Haiyuan County is at a medium to high level, and the spatial differences are large. The spatial distribution pattern has strong agglomeration characteristics. The areas with high ecological vulnerability mainly distribute along rivers with high development intensity and frequent human activities, river valley areas and southern areas with high elevation and large topography; from the perspective of poverty, the proportion of administrative villages with moderate poverty and above in Haiyuan County is 55.72%, indicating that the overall poverty in the study area is relatively deep, and severe poverty and extreme poverty concentrate in the southern and western regions with high altitude, large slope and undulating terrain; from the perspective of the coupling relationship between ecology and economy, the degree of coordination between ecological fragility and economic poverty in the study area is low, and the proportion of coordinated and synchronous development is 10.71%, and the unbalanced environment is lagging. The number of administrative villages with unbalanced economic backwardness is the largest, and their spatial distribution relatively concentrate, mainly in the eastern and southern regions of Haiyuan County.
