基于迫切–适宜度的农村居民点整治时空配置研究

Spatial-Temporal Collocation of Rural Residential Land Consolidation Based on Interaction of Urgency and Suitability Degree

按照农村居民点整治的时空维度特征,以实现农村居民点整治的多目标性为导向,将不同目标实现的影响因素归类为整治迫切性和适宜性两方面,利用迫切–适宜度综合评价与互斥性组合矩阵,列举农村居民点整治的目标差异化时序安排,构建多目标导向的农村居民点整治空间组织与配置格局。使用该方法,将北京市平谷区农村居民点整治的时间迫切性划分为高度、中度、低度和不迫切4个等级,村庄数量比例分别为12.73%,28.36%,24.73%和34.18%,空间上表现出迫切性等级由高到低的圈层结构特征;农村居民点整治的空间适宜性划分为高度、中度、低度和不适宜4个等级,村庄数量比例分别为11.27%,33.09%,36.73%和18.91%,具有明显的空间组团式分布特点;综合迫切–适宜性等级结果,形成农村居民点优先整治区、重点整治区、适度整治和限制整治区的时空配置格局,并提出不同分区农村居民点整治的目标导向和保障措施。

Firstly, according to the spatial-temporal characteristics of rural residential land consolidation, in order to guide the multiple target of rural residential land consolidation, the influence factors of different.goals are classified as two aspects, which are urgency and suitability of rural residential land consolidation. Secondly, with the comprehensive evaluation of rural residential land consolidation urgency-suitability degree and construction of exclusive matrix combining method, the authors list the different target scheduling of rural residential land consolidation and establish the spatial organization and allocation pattern under the guidance of multiple target. The case study in Pinggu district in Beijing show that time urgency of rural residential land consolidation is divided into four grades, high, moderate, low and no urgency, and the proportions of village number are 12.73%, 28.36%, 24.73% and 34.18% accordingly. Characteristics of special distribution is urgency level from high to low layer structure. Space suitability of rural residential land consolidation is divided into four grades, high, moderate, low and no suitability, and the proportions of village number are 11.27%, 33.09%, 36.73% and 18.91% accordingly. There is obvious group layer structure in special distribution of village. Combining with urgency and suitability level results, the spatial-temporal collocation pattern for rural residential consolidation land is formatted, which are the priority areas in the near future, the key areas in the medium term, the suitable areas in the long termand limiting consolidate. The goal orientation and safeguard measures in different areas of rural residential land consolidation has also been put forward.
