- Abstract:
- The purpose of this study is to explore optimal adjustment method of rural settlement layout in Dayushu Town of the Hinterland of Sanjiang Plain. The evaluation indicator system of nodular index for rural settlement patches is built, and then the nearest neighbor index and variation coefficient are employed to determine the rank type of rural residential patches. Using methods of extended break-point model of weighted Voronoi diagram, spatial point pattern and the two-step floating catchment area method, this pape analyzed layout optimization scheme of rural residential patches. The results indicate that: (1) the patches which have a bigger nodule index mainly distribute around the town center and traffic trunk lines with significant location advantage, perfect infrastructure and higher agricultural mechanization level. Meanwhile, the patches of the smaller nodule index distribute remotely and present scatter distribution; (2) the patches number for central village, basic village, migration village and scattered village are 13,20,22 and 13, respectively; four kinds of layout optimization strategies including priority development, restrictive development, combined migration and stressed harness are put forward; (3) according to the weighted Voronoi diagram and the two-step floating catchment area method, the directions of some rural settlement migrations are determined; an optimal scheme to spatial distribution adjustment for rural residential patches in Dayushu town is formulated. The research results can provide theoretical bases for the layout adjustment of rural settlements and agricultural production in Sanjiang Plain.
