Abstract:

The study of the spatial evolution of rural settlements at micro-scale contributes to the deep understand of the diversity of settlement evolution. The paper discusses the multivariate space evolution model of the typical karst rural settlements in the Guizhou Plateau at patch scale and aims to reveal the diversity of rural settlements in karst mountainous areas, which is important to promote the reconstruction model in suitable production, living and ecological space in karst mountainous villages. The high resolution remote sensing images with long time series from 1963 to 2015 and the field surveys of local households are the main data sources. In order to reflect the spatial distribution pattern of the settlements in the study area, the average neighborhood index, the patch density per unit area and the percentage of the settlement area are defined, and the types of settlement evolution are divided based on the space composition of new and old settlement houses. The results show that the overall settlements in the study area can be characterized as “dense in the peripheral area and sparse in the middle”, and this kind of spatial pattern had been continuously strengthened from 1963 to 2015. The types of settlement evolution can be divide into “hollowing out and abandoned type”, “Old declined and new built-up type”, “natural fading type”, “internal reconstruction type”, “basically unchanged type” and “comprehensive evolution type”. In 1963, the settlements mixed with old and new buildings in the study area accounted for 71.83% of the area, and the settlements dominated with old buildings accounted for 28.17% of the area. In 2015, the settlements mixed with old and new buildings, the settlements dominated with old buildings and the settlements dominated with new buildings accounted for 45.14%, 28.07% and 26.79% of the total area, respectively. The settlement landscape in the study area experienced the evolution process of mixture of old and new buildings, old buildings dominated and new buildings dominated from 1963 to 2015. The multiple paths of the settlement evolution in the study area can be summarized as three types: lowland oriented, traffic oriented and economy and central area oriented. Based on the above results, this paper argues that the remediation of the settlement and the spatial optimization and control in the study area should be based on the multiple evolution models.
