- Abstract:
- Identifying the spatial differentiation and correlation characteristics of rural settlements is an important foundation and prerequisite for the optimization of rural settlement layout. In order to explore the spatial characteristics and differences of rural settlements in the poverty belt around Beijing and Tianjin, the poverty belt around Beijing and Tianjin was taken as the research area, the spatial differentiation characteristics of rural settlements for 2005 and 2015 were quantitatively analyzed based on the method of GIS technology, kernel density and landscape pattern indices. The theory of spatial dependence was introduced, and exploratory spatial data and spatial econometric model were applied to deeply analyze the spatial correlation and influencing factors to the form of spatial distribution for the rural settlements. The results indicated that:(1)there were obvious spatial distribution in the poverty belt around Beijing and Tianjin, showing the distribution characteristics of denser level in the southeast and the north-west and sparse level in the north; compared with 2005, the scale of rural settlements had gradually increased, the patch complexity was relatively high, and the rural settlement plaque form was increasingly complex in 2015;(2)in general, there is a significant effect of spatial correlation between the spatial distributions of rural settlements in the poverty belt around Beijing and Tianjin; compared with 2005, the concentration of rural land in space was weakened and the tendency of concentration distribution spatial heterogeneity became significant in some local areas in 2015;(3)the influence of different factors on the spatial distribution of rural settlements in the poverty belt around Beijing and Tianjin had significant differences, the influence degree of the factors decreased in the order: distance from rivers>slope>elevation>the distance from road>the distance from town to town; the influences of the distance from rivers, slope, elevation, the distance from road on the spatial distribution of rural settlements were all continuously increasing and the influence of the distance from town to town was gradually decreasing. These results can provide a scientific decision for optimization of rural settlements and coordinated development of Beijing-Tianjin-Hebei region in the poverty belt around Beijing and Tianjin, and provide the scientific basis for poverty alleviation and wealth creation of similar underdeveloped areas.
