中文摘要: |
研究长时段农村居民点用地的动态变化,对推进农村土地整治、优化村镇格局具有基础性的指导作用。基于县域单元,采用综合指标法、地理探测器等分析方法,揭示 1995 年、2005 年和 2015 年安徽省农村居民点用地的空间密度、变化数量特征及空间分布特征,并分析用地变化的影响因素。结果表明:①县域尺度上,皖北地区的农村居民点用地净变化率和结构变化率低于皖南地区,存在市区周围农村居民点用地减少的情况。②在空间特征上,安徽省形成“皖北密集区”和“皖南稀疏区”,其中密度最大地区分布在以阜阳市和亳州市为代表的安徽西北部地区。③农村人口、人均粮食产量、农业机械总动力、高程、农村人均收入是影响农村居民点数量变化的主要因素。人均 GDP、农林牧渔总产值、城市化率对农村居民点变化的影响较小。在乡村振兴的背景下,建议通过加强信息技术手段对农村居民点用地进行监测,实现农村土地资源利用的合理化发展。 |

Studying the dynamic changes of rural residential land use over a long period of time has a fundamental guiding role inadvancing rural land consolidation and optimizing the pattern of villages and towns. Based on the county unit,using comprehensiveindex method,geographic detector and other analysis methods to reveal the spatial density,change quantitative characteristicsand spatial distribution characteristics of rural residential land use in Anhui Province in 1995,2005 and 2015,and analyze theinfluencing factors of land use change . The results show that: ① At the county scale,the net change rate and structural change rate ofrural residential land use in northern Anhui are lower than those in southern Anhui,and there is a decrease in rural residential landuse around the urban area. ③ In terms of spatial characteristics,Anhui Province has formed "density areas in northern Anhui" and"sparse areas in southern Anhui",among which the densest areas are distributed in northwestern Anhui represented by Fuyang andBozhou. ③ Rural population,per capita food production,total power of agricultural machinery,elevation,and rural per capitaincome are the main factors affecting the changes in the number of rural settlements. Per capita GDP,total output value of agriculture,forestry,animal husbandry and fishery,and urbanization rate have little impact on changes in rural settlements. In the context of ruralrevitalization,it is recommended to monitor the land use of rural residential areas by strengthening information technology to realize therational development of rural land resource utilization. |
