农村居民点迁移合并是土地整理实施过程遇到的实际问题,其研究结果可为土地利用总体规划及镇村布局规划的编制提供依据。该文基于中心地理论,选择农村居民点斑块为研究对象,分析了农村居民点斑块综合影响力的影响因素,构建了综合影响力的评价指标体系。由层次分析法确定了指标权重,单元总分加权法计算了单元的分值,Natural breaks法划分了农村居民点斑块等级,并提出了农村居民点斑块空间布局优化的策略。之后,基于加权Voronoi图扩展断裂点模型,计算了优势农村居民点斑块的空间影响范围,研究了被迁移的农村居民点斑块的迁移方向。研究结果表明:区位因素、居民点因素、资源因素和经济因素是朱林镇农村居民点斑块综合影响力的主要影响因素。中心村、核心村、自然村和零星村落4个等级的农村居民点斑块在规模和数量上等级结构明显。不同等级的农村居民点斑块其影响力不同,应采用重点发展、限制发展、迁移合并和政策保留等策略优化农村居民点空间布局。规模小、影响力低的农村居民点斑块应迁移到附近规模大、影响力高的农村居民点斑块,以保持农村居民点斑块结构稳定。该研究结果符合朱林镇的实际情况,为镇村布局规划的编制提供了依据。
農村居民點遷移閤併是土地整理實施過程遇到的實際問題,其研究結果可為土地利用總體規劃及鎮村佈跼規劃的編製提供依據。該文基于中心地理論,選擇農村居民點斑塊為研究對象,分析瞭農村居民點斑塊綜閤影響力的影響因素,構建瞭綜閤影響力的評價指標體繫。由層次分析法確定瞭指標權重,單元總分加權法計算瞭單元的分值,Natural breaks法劃分瞭農村居民點斑塊等級,併提齣瞭農村居民點斑塊空間佈跼優化的策略。之後,基于加權Voronoi圖擴展斷裂點模型,計算瞭優勢農村居民點斑塊的空間影響範圍,研究瞭被遷移的農村居民點斑塊的遷移方嚮。研究結果錶明:區位因素、居民點因素、資源因素和經濟因素是硃林鎮農村居民點斑塊綜閤影響力的主要影響因素。中心村、覈心村、自然村和零星村落4箇等級的農村居民點斑塊在規模和數量上等級結構明顯。不同等級的農村居民點斑塊其影響力不同,應採用重點髮展、限製髮展、遷移閤併和政策保留等策略優化農村居民點空間佈跼。規模小、影響力低的農村居民點斑塊應遷移到附近規模大、影響力高的農村居民點斑塊,以保持農村居民點斑塊結構穩定。該研究結果符閤硃林鎮的實際情況,為鎮村佈跼規劃的編製提供瞭依據。

The objective of the research was to optimize the combination of rural settlement along with land consolidation implementation. The result could be used for decision making associated with planning of land use and rural settlement spatial pattern. <br> Based on central place theory, this study analyzed external and internal influencing factors of comprehensive influence (RSPCI) for rural settlement patch to build evaluation indicator system of comprehensive influence for rural settlement patches. The indicator system weights of RSPCI was evaluated by applying AHP, and the value of RSPCI for each rural settlement patch was calculated by applying unit score weighting. Then, the rural settlement patches and identified optimization strategies were classified according to Jenks natural breaks classification method. Finally, spatial impact range of core at village level based on extended break-point model of weighted Voronoi diagram and the direction of migration of rural settlements were determined in order to optimize the spatial pattern of rural settlements. <br> The results showed that the indicator systems of RSPCI in Zhulin town included four factors:location, residential settlement, natural resources and economics. The weight for each of them was 0.11, 0.31, 0.28 and 0.30 respectively. The rural settlements were divided into four levels based on value of RSPCI including central village, core village, natural village and scattered village levels. The hierarchical structures for different levels of rural settlement were obvious in terms of size and the number. Four kinds of optimization strategies including priority development, restrictive development, combined migration and retention policies should be used to optimize spatial pattern and layout of rural settlement. Among 466 rural settlement patches in the town, 28 were given with full priority to develop, 193 were given with limited priority to develop, 244 were combined and migrated, and 1 was reserved. The migration direction of 244 patches was given by extended break point model of weighted Voronoi diagram. Therefore, rural settlement patches for different levels showed different influences on scope. As a result, different spatial layout optimization strategies should be employed for different rural settlement patches. In order to maintain a stable structure for residential settlement patches, rural settlement patches with low comprehensive influence should be migrated to those with high comprehensive influence during rural settlement consolidation. The results above proposed tools for officers of land management departments in government to make informed decisions for implementing new land use and planning policies.
