Research On Spatial Consolidation Of Rural Settlements Based On Modified Gravity Model

For a long time, the spatial layout of rural settlements exist quantity, widelydistributed, small-scale features, and spatial distribution of scattered rural settlementslargely inefficient pattern of restricting the sustainable socio-economic development of theregion, how to solve rural residential space layout disorders, to fully tap its internalpotential, in order to achieve change by the extension and expansion of rural residentialdevelopment to content development, integration of urban and rural development is whenthe problems to be solved.On the other hand, the gravity model analysis of different regions of space as acentral tool of interaction is widely used in economic geography and regional geographyresearch and analysis, the gravity model based on the characteristics of rural settlementscorrection, you can optimize the layout of rural residential space provide a scientific basis.On this basis, the select group of Poyang County Forest Township as a study area, toexplore the relationship between rural residential space, improved rural settlements gravitymodel analysis features, elements, calculation method, the gravitational mass and thedistance between the two model parameters reconstruction and revision, the final measuregravitational rural settlements and the corresponding value of the spatial layoutoptimization strategy based on the value of gravity grading results. Studies have shownthat:(1) Comprehensive application of GIS and spatial analysis of AHP, from naturalconditions, economic base, social life, the policy implications of the gravitational masssettlements comprehensive evaluation system constructed four groups Township Farmers’village, improved gravity model gravitational mass is calculated, you can measure out amore comprehensive gravitational mass gravitational mass groups Township Farmers’village settlements and11villages centers, mostly in the Institute of obtaining valuesbetween21-52;(2) by building tuanlin rural road network data sets, introduced OD matrix can beeasily and accurately measure each of the11rural settlements to the administrative centerof the village from the road network as an alternative to the simple gravity model lineardistance. Each institute must generate11rural settlements each path between theadministrative center of the village, a total of1573paths, so that the gravity model tostudy the interaction in a rural residential space more practical and operational aspects.(3) the use of quality parameters and distance parameters modified gravity model canwell support the layout and structure of rural residential space optimization. According tothe spatial effects of gravity value, and ultimately determine the priority groups TownshipFarmers’ village residential development type15, type78keep tapping, shrink and decline of type50, and the corresponding regulatory direction, to the new ruralconstruction and rural land remediation process the " village relocation and " provide areference.(4) rural settlements is a mutual influence, interrelated economic and social ecologicalcommunity, the performance of the town, the center of the village near the village withthe grass roots of a mutual attraction organic network within the region. Gravity model toplay in geography and regional economics, an important theoretical support, can well beused to simulate the spatial structure of rural residential land in connection strengthbetween the relevant factors for rural residential space layout optimization analysisprovides a powerful support.
