【摘要】 深入探究建设用地扩张与土地利用冲突的动态变化及其空间关系，对于促进城市健康发展以及实现土地资源的合理配置与综合管理具有重要意义。本研究首先对河北省2000-2020年建设用地扩张的强度与模式进行量化，然后基于景观生态风险评价模型对土地利用冲突程度进行评价，最后基于地理加权回归模型分析建设用地扩张对土地利用冲突变化的影响。研究结果表明：(1)2000-2020年，河北省建设用地扩张强度呈现显著的“东南高，西北低”空间分异特征，其中西北部地区扩张模式趋于分散，呈现“飞地式”发展态势。(2)2000-2020年，土地利用冲突强度呈先降后升的特征，空间分布表现为“西北高，东南低”的格局，其变化值由东南向西北递减。(3)建设用地扩张对土地利用冲突变化的影响具有显著时空异质性：2000-2010年扩张强度对土地利用冲突变化主要呈正向影响，而2010-2020年主要转为负向影响，扩张模式在整个研究期主要对冲突变化产生负向影响。更多还原

【Abstract】 It is of great significance for promoting the healthy development of the city and realizing the rational allocation and comprehensive management of land resources to deeply explore the changes and spatial relationship between construction land expansion and land use conflict. This study first quantified the intensity and mode of construction land expansion in Hebei Province from 2000 to 2020, then evaluated the degree of land use conflict based on the landscape ecological risk assessment model, and finally analyzed the impact of construction land expansion on land use conflict changes based on the geographically weighted regression model. The results show that:(1) From 2000 to 2020, the expansion intensity of construction land in Hebei Province showed a significant spatial differentiation characteristic of "high in southeast and low in northwest".(2) From 2000 to 2020, the intensity of land use conflict decreased first and then increased, and the spatial distribution showed a pattern of "high in the northwest and low in the southeast". The change value decreased from southeast to northwest.(3) The impact of construction land expansion on land use conflict change has significant spatial and temporal heterogeneity. From 2000 to 2010, the expansion intensity had a positive impact on land use conflict change, while from 2010 to 2020, it mainly turned into a negative impact.更多还原
