摘要:

以黄土高原地区宁夏西吉县为对象,从县域到农户不同尺度,研究生态脆弱地区与贫困地区乡村聚落空间变化特征及其影响因素,在经济社会不断发展的背景下,西吉县的乡村聚落数量和规模均明显增长,并呈现向生态环境较好、交通便利地区集中的基本特征.对于空间变化的影响因素:在宏观层面上,人口与经济增长是主要驱动力,政府移民、建筑结构升级也显著推动村庄演化,但在人口增长快、生态不断退化的压力下,乡村发展进入搬迁-生态恶化-贫困加剧的恶性循环,这是生态脆弱、发展模式粗放和经济滞后导致的共同结果.在微观层面,从农户的角度出发,利用Logistic回归分析发现,乡村聚落空间变化的核心原因是分家、外出务工等社会因素、而非收入增长等经济因素.

关键词: 西吉县, 乡村聚落, 空间变化, 影响因素

Abstract:

This work takes Xiji as a typical area to investigate the development trend and its influence factors in the ecological fragile areas and poor areas from county level to farmer level. Under the background of economic and social development, the number and size of villages significantly increased and concentrated on good ecological environment and traffic convenient areas. The influencing factors are analyzed. At the macro level, population and economic growth are the main driving forces. The government immigration and structure upgrade also significantly contribute to the space evolution of rural settlements. Under the background of population pressure and ecological degradation, rural development in Xiji has entered a vicious cycle: relocation-ecological deterioration-increasing poverty, which is the result of fragile ecology, extensive development mode, and lagging economy. At the micro level (from farmer's respect), the core reasons of spatial variation of rural settlements are found to be the family separation, working outside, and other social factors rather than revenue growth, based on Logistic regress analysis.

Key words: Xiji, rural settlement, space change, influence factor
