【摘要】：空间贫困研究是对多维贫困理论的丰富和发展,创新空间贫困度量方法是精准配置扶贫资源和提高农村扶贫质量的关键。本文借鉴国际空间贫困研究的基本理论思想,总结出了空间贫困三维结构分析框架,构建了县域空间贫困指标体系和地理识别方法,以宁夏泾源国家扶贫开发重点县为例,开展了空间贫困地理识别。研究发现:(1)不同自然地理区SPI排序为侵蚀堆积河谷平川区(均值1.571)剥蚀构造丘陵区(均值-0.199)侵蚀构造石山区(均值-0.334),表明侵蚀构造石山区贫困程度最大,是减贫重点区域,其中3个自然地理区空间贫困的共同特点是存在经济劣势(C_4~C_7、C_(17)),主要差异是侵蚀堆积河谷平川区生态劣势(C_(25)、C_(16))经济劣势(C_5)位置劣势(C_(20))政治劣势(C_8);剥蚀构造丘陵区经济劣势(C_5~C_7、C_(17))位置劣势(C_(18)~C_(20))生态劣势(C_(16)、C_(23)~C_(25))政治劣势(C_8);侵蚀构造石山区经济劣势(C_4~C_7、C_(17))政治劣势(C_8)位置劣势(C_(18)~C_(20))生态劣势(C_(16)、C_(21)~C_(25))。(2)不同民族村SPI排序为汉族村(均值1.484)回族村(均值1.262)回汉混居村(均值-1.033),表明县域尺度上回汉混居村是减贫重点村。不同民族村空间贫困的共同特征是由于距离最近市场远(C_(17))形成的经济劣势,以及人均耕地面积(C_(23))和农作物特别经济作物种植面积小(C_(24))形成的生态劣势。不同民族村空间贫困的主要差异在于汉族村人居环境差和灾损率高形成的生态劣势,以及贷款不足(C_5)导致的经济劣势突出,回族村主要因文化知识素质较低(C_(12)、C_(13))导致进入市场的机会成本高而形成经济劣势,回汉混居村因汉族和回族生产生活方式差异,造成扶贫资源配置困难,农户对扶贫政策满意率最低(C_8),反映该类村空间贫困的政治劣势最为显著。(3)同一自然地理区域不同民族村空间贫困存在显著差异。侵蚀堆积河谷平川区汉族村、回族村和回汉混居村SPI均值分别为0.526、2.557和1.644,表明该类型区汉族村贫困程度高,经济劣势显著(C_5);剥蚀构造丘陵区回族村和回汉混居村的SPI均值分别约为0.321和-1.934,表明该类型区回汉混居村贫困程度较高,经济劣势(C_2、C_6、C_7)和生态劣势(C_(16))突出;侵蚀构造石山区汉族村、回族村和回汉混居村的SPI均值分别为1.031、-0.029和-0.842,表明该类型区回汉混居村贫困程度亦高,经济劣势(C_5~C_7、C_(17))、政治劣势(C_8)、位置劣势(C_(18)~C_(20))和生态劣势(C_(16)、C_(25))并存。因此,侵蚀堆积河谷平川区的汉族村、剥蚀构造丘陵区和侵蚀构造石山区的回汉混居村是减贫重点村。
[Abstract]:The research on spatial poverty is the enrichment and development of multidimensional poverty theory, and the innovation of spatial poverty measurement is the key to the accurate allocation of poverty alleviation resources and the improvement of rural poverty alleviation quality. This paper draws lessons from the basic theory of international space poverty research, summarizes the three-dimensional structure analysis framework of spatial poverty, constructs the index system and geographical identification method of spatial poverty at the county level, and takes the key counties of poverty alleviation and development of Jingyuan state in Ningxia as an example. Geographical identification of spatial poverty was carried out. It is found that the SPI order of different natural geographical regions is erosion accumulation valley, Pingchuan area (mean 1.571), erosion tectonic hilly area (mean value -0.199), erosion tectonic stone mountain area (mean value -0.334), which indicates that the eroded tectonic stone mountain area is the most impoverished area and is the key area for poverty reduction. The common feature of spatial poverty in three of the physical geographic areas is that there is an economic disadvantage in Che 4C7C / C / T, the main difference is that the ecological inferiority of Pingchuan district in the accumulated valley is eroded and the ecological inferiority of the Pingchuan area is eroded. The main difference is that the economic disadvantage is the economic inferiority C5) the economic inferiority is C5) and the political inferiority is C8#; the economic inferiority of the eroded hilly area is C8#; the economic inferiority of the eroded structural hilly area is poor. 鍔，
