摘　　要：针对哈尔滨市土地利用的定量论证问题,从区县尺度分析多时段用地转化特征动态演变有助于得出更精细的结果,为地方政府部门和合理制定规划政策提供理论支持。本文采用2014—2022年哈尔滨市区县各项遥感影像数据,结合GDP、人口、DEM、坡度、气温、降水等影响因子数据信息,离散化后用土地覆被转移矩阵分析哈尔滨市土地利用覆被类型变化情况,引入地理探测器用单因子贡献率分析和多因子交互贡献率分析方法,探究了哈尔滨市近十年的用地变化的贡献度,综合分析了区县级土地利用时序演变特征及LUCC时序演变的多因子协同驱动机制,多因子交互贡献率对土地覆盖空间分布影响力体现为哈尔滨市土地利用的整体健康和可持续发展。Addressing the issue of quantitative demonstration of land use in Harbin,analyzing the dynamic evolution of multi-period land use conversion characteristics from the district-county level scale can help to achieve more detailed results and it provides theoretical support for local government departments in planning and formulating policies.This paper utilizes remote sensing image data from various districts and counties in Harbin from 2014 to 2022,combined with information of influencing factors such as GDP,population,DEM,slope,temperature,and precipitation.After discretization,the land cover transfer matrix is used to analyze the changes in land use and cover types in Harbin.The geodetector is introduced to analyze the contribution of single-factor and multi-factor interactions to land use changes in Harbin over the past decade.The paper comprehensively analyzes the temporal evolution characteristics of land use at the district-county level and the multi-factor synergistic driving mechanisms of LUCC temporal evolution.The influence of multi-factor interaction contribution rates on the spatial distribution of land cover reflects the overall health and sustainable development of land use in Harbin.
