Analysis of Temporal Evolution and Driving Mechanisms of LUCC at Urban and County Levels in Harbin in the Past Decade
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 theoret-ical 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 develop-ment of land use in Harbin.
