【摘要】：空間貧困研究是對(duì)多維貧困理論的豐富和發(fā)展,創(chuàng)新空間貧困度量方法是精準(zhǔn)配置扶貧資源和提高農(nóng)村扶貧質(zhì)量的關(guān)鍵。本文借鑒國(guó)際空間貧困研究的基本理論思想,總結(jié)出了空間貧困三維結(jié)構(gòu)分析框架,構(gòu)建了縣域空間貧困指標(biāo)體系和地理識(shí)別方法,以寧夏涇源國(guó)家扶貧開(kāi)發(fā)重點(diǎn)縣為例,開(kāi)展了空間貧困地理識(shí)別。研究發(fā)現(xiàn):(1)不同自然地理區(qū)SPI排序?yàn)榍治g堆積河谷平川區(qū)(均值1.571)剝蝕構(gòu)造丘陵區(qū)(均值-0.199)侵蝕構(gòu)造石山區(qū)(均值-0.334),表明侵蝕構(gòu)造石山區(qū)貧困程度最大,是減貧重點(diǎn)區(qū)域,其中3個(gè)自然地理區(qū)空間貧困的共同特點(diǎn)是存在經(jīng)濟(jì)劣勢(shì)(C_4~C_7、C_(17)),主要差異是侵蝕堆積河谷平川區(qū)生態(tài)劣勢(shì)(C_(25)、C_(16))經(jīng)濟(jì)劣勢(shì)(C_5)位置劣勢(shì)(C_(20))政治劣勢(shì)(C_8);剝蝕構(gòu)造丘陵區(qū)經(jīng)濟(jì)劣勢(shì)(C_5~C_7、C_(17))位置劣勢(shì)(C_(18)~C_(20))生態(tài)劣勢(shì)(C_(16)、C_(23)~C_(25))政治劣勢(shì)(C_8);侵蝕構(gòu)造石山區(qū)經(jīng)濟(jì)劣勢(shì)(C_4~C_7、C_(17))政治劣勢(shì)(C_8)位置劣勢(shì)(C_(18)~C_(20))生態(tài)劣勢(shì)(C_(16)、C_(21)~C_(25))。(2)不同民族村SPI排序?yàn)闈h族村(均值1.484)回族村(均值1.262)回漢混居村(均值-1.033),表明縣域尺度上回漢混居村是減貧重點(diǎn)村。不同民族村空間貧困的共同特征是由于距離最近市場(chǎng)遠(yuǎn)(C_(17))形成的經(jīng)濟(jì)劣勢(shì),以及人均耕地面積(C_(23))和農(nóng)作物特別經(jīng)濟(jì)作物種植面積小(C_(24))形成的生態(tài)劣勢(shì)。不同民族村空間貧困的主要差異在于漢族村人居環(huán)境差和災(zāi)損率高形成的生態(tài)劣勢(shì),以及貸款不足(C_5)導(dǎo)致的經(jīng)濟(jì)劣勢(shì)突出,回族村主要因文化知識(shí)素質(zhì)較低(C_(12)、C_(13))導(dǎo)致進(jìn)入市場(chǎng)的機(jī)會(huì)成本高而形成經(jīng)濟(jì)劣勢(shì),回漢混居村因漢族和回族生產(chǎn)生活方式差異,造成扶貧資源配置困難,農(nóng)戶(hù)對(duì)扶貧政策滿(mǎn)意率最低(C_8),反映該類(lèi)村空間貧困的政治劣勢(shì)最為顯著。(3)同一自然地理區(qū)域不同民族村空間貧困存在顯著差異。侵蝕堆積河谷平川區(qū)漢族村、回族村和回漢混居村SPI均值分別為0.526、2.557和1.644,表明該類(lèi)型區(qū)漢族村貧困程度高,經(jīng)濟(jì)劣勢(shì)顯著(C_5);剝蝕構(gòu)造丘陵區(qū)回族村和回漢混居村的SPI均值分別約為0.321和-1.934,表明該類(lèi)型區(qū)回漢混居村貧困程度較高,經(jīng)濟(jì)劣勢(shì)(C_2、C_6、C_7)和生態(tài)劣勢(shì)(C_(16))突出;侵蝕構(gòu)造石山區(qū)漢族村、回族村和回漢混居村的SPI均值分別為1.031、-0.029和-0.842,表明該類(lèi)型區(qū)回漢混居村貧困程度亦高,經(jīng)濟(jì)劣勢(shì)(C_5~C_7、C_(17))、政治劣勢(shì)(C_8)、位置劣勢(shì)(C_(18)~C_(20))和生態(tài)劣勢(shì)(C_(16)、C_(25))并存。因此,侵蝕堆積河谷平川區(qū)的漢族村、剝蝕構(gòu)造丘陵區(qū)和侵蝕構(gòu)造石山區(qū)的回漢混居村是減貧重點(diǎn)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，
