摘要:

为探讨在生态文明理念的指引下新时代农村国土综合整治差异化路径，本研究从农村国土综合整治的关注重点出发，在效率、品质、形态、文化等4 个方面构建指标体系，对全国范围内农村国土利用水平进行本底评价，采用ArcGIS探索性空间数据分析，对评价结果进行限制、优势性因素识别，再叠加形成限制性及优势性因素分级，并根据区域差异提出针对性的整治实施路径。结果表明:1)我国农村国土利用水平区域差异明显，总体呈现东部高、西部低的空间分布格局，高值区主要分布在华北平原及沿海地区，低值区多分布在中西部地区以及西南地区；2)各评价子系统空间分布集聚程度较高，高值区及低值区空间分布呈现明显规律性并具有显著的地域性；3)各区域限制性因素和优势性因素差异显著，东部无限制区应进行全域农村国土综合整治，打造乡村振兴示范区，东北地区应当注重品质的提升，西南地区应着重提升土地利用效率。

Abstract:

To explore the regionalization and implementation approaches for rural integrated territory consolidation in China under the concept of ecological civilization. An indicator system is constructed considering the following four aspects, e. g. efficiency, quality, form, and culture from the focus of rural integrated territory consolidation. The utilisation level of rural land is evaluated. Based on the exploratory spatial data analysis of ArcGIS, the evaluation results are limited and the advantages are identified, which are then superimposed to form the classification of limitations and advantageous factors. The targeted consolidation implementation approaches are proposed in this study according to different regional characteristics. The results show that: 1)There are obvious regional differences in the level of rural land use in China. The overall distribution pattern is high in the east and low in the west. The high-value areas are mainly distributed in the North China Plain and coastal areas, while the low-value areas are mostly distributed in the central and western regions and southwest regions. 2)The spatial distribution of each evaluation subsystem is highly concentrated, and the spatial distribution of high-value and low-value areas presents obvious regularity and significant regional characteristics. 3)There are significant differences between restrictive and advantageous factors in different regions. In the eastern unrestricted area, comprehensive rural integrated consolidation should be carried to create a rural revitalization demonstration area. Attentions should be focused on quality improvement in the northeast area and efficiency promotion in the southwest area.
