Analysis of the Impact of the Integrated Conservation and Restoration Project of Mountains,Rivers,Forests,Farmlands,Lakes,Grasslands,and Deserts on the Landscape Pattern in Central Heilongjiang Province
From the perspective of landscape patterns,this study explores the impact of land use changes in the Lesser Khin-gan Mountains and Sanjiang Plain region concerning the influence of the integrated conservation and restoration(ICR)project of mountains,rivers,forests,farmlands,lakes,grasslands and deserts,and analyzes its response trend and correlation mecha-nism.The aim is to provide insights for regional land consolidation and ecological restoration decision-making.Spatial-temporal dynamic analysis was conducted using land use transfer matrices and GIS spatial analysis methods.Landscape pattern indices were measured,and a global regression linear model based on land use and landscape pattern changes under the influence of the ICR project was constructed to analyze the associated impacts and reasons for different land uses on landscape patterns in this scenario.Significant changes in land use types have occurred since the implementation of the ICR project,leading to corresponding responses in landscape patterns.The overall connectivity of the region showed an initial decrease followed by an increase,while fragmentation,complexity,and heterogeneity exhibited an initial increase followed by a decrease.In the global model,farmland types showed the highest correlation among various landscape pattern characteristics,followed by forest and built-up land types.Different land uses,such as farmland and forest land,exhibited various interactive effects on different landscape characteristics.Additionally,variations in landscape pattern responses were observed in differ-ent spatial locations within the region.Under the influence of the ICR project,farmland types played a dominant role in the changes in landscape patterns.The expansion of farmland promoted landscape dominance and connectivity,while mitigating fragmentation and heterogeneity.The response of landscape fragmentation,complexity,and heterogeneity in the Lesser Khingan Mountains region was significant,as was the improvement in connectivity and complexity in the Sanjiang Plain region.This highlights the differential responses of landscape patterns to land use changes in different regions.
