备注

区域土地利用冲突诊断及其冲突原因的解释可为缓解区域用地矛盾提供理论基础。以沈阳经济区为研究区,从“三生”功能视角建立土地利用冲突诊断模型,对1980—2018年研究区土地利用冲突进行诊断,并测算区域土地利用强度验证土地利用冲突诊断结果,采用小波相干模型,提取研究区土地利用冲突的关键影响因素,进而确定研究区土地利用冲突关键影响因素的作用大小和作用方式。结果表明:(1)土地利用冲突诊断结果的变化趋势大致相同,总体可分为平稳上升(1980—2000年)、快速上升(2000—2013年)和先下降后上升(2013—2018年)3个变化阶段; 在空间分布上基本保持西高东低的稳定分布;(2)经验证,研究区土地利用冲突剧烈的区域土地利用强度相应也较大;(3)1980年以来影响沈阳经济区土地利用冲突的7个关键影响因素分别为GDP增量、第三产业产值比例、第二产业产值比例、工业总产值、第一产业产值比例、人均可支配收入和能源消耗量;(4)1980—2018年研究区土地利用冲突的关键影响因素对区域土地利用冲突产生促进和抑制作用的具体时段和时点各不相同,同一关键影响因素在不同时点对土地利用冲突亦会产生不同的作用方式。研究成果可为缓解决区域用地矛盾、促进东北振兴提供参考。
The diagnosis of regional land use conflicts and the explanation of its causes can provide a theoretical basis for alleviating the contradiction of regional land use. This study took Shenyang Economic Zone as the study area to establish the land use conflicts diagnosis model from the ‘Production-Living-Ecological' function angle, diagnose the land use conflicts in the study area from 1980 to 2018, and calculate the regional land use intensity to verify the land use conflicts diagnosis result. The results showed that:(1)the trend of land use conflicts diagnosis was roughly the same, which could be divided into three stages: steady rise(1980—2000), rapid rise(2000—2013)and first decline and then rise(2013—2018); the spatial distribution basically maintained the stable distribution of high in west of the study area and low in east of the study area;(2)it was proved that the corresponding land use intensity in the area of serious land use conflict in the study area was also high;(3)the seven key influencing factors of land use conflicts in Shenyang Economic Zone were GDP increment, tertiary industry output value ratio, secondary industry output value ratio, industrial output value ratio, primary industry output value ratio, per capita disposable income and energy consumption from 1980 onwards;(4)the key influencing factors of land use conflicts in the study area from 1980 to 2018 had different time periods and time points, and the same key influencing factors had different modes of action on land use conflicts at different time points. These results could provide reference for solving the contradiction of regional land use and promoting the revitalization of Northeast China.
