Analysis of the Spatio-temporal Pattern Evolution and Driving Factors of the Production-Living-Ecological Space in Northeast China

Abstract:ObjectiveScientific understanding of the evolution of the spatial pattern of production-living-ecological space under long-term regional time series is an important prerequisite for the improvement of the national space development and protection system. Methods Based on five periods of land use data from 1980 to 2020, combined with land use dynamic attitude and transfer matrix, grid analysis, spatial autocorrelation analysis, triangular graph analysis, geographic detector and other methods, this paper analyzed the spatial distribution scale, spatio-temporal variation characteristics, spatial clustering and driving factors of production-living-ecological space pattern evolution in Northeast China. Results (1) Production-living-ecological space in Northeast China presents a pattern of "ecological dominance and production support". Ecological space (67.42%), production space (29.95%) accounted for a significant proportion, living space (3.89%) expansion rate is the fastest. (2) The evolution of production-living-ecological space shows that the production space is first rising and then stable, the living space is gradually rising, and the ecological space is fluctuating and declining. The ecological space of grassland, woodland and other ecological Spaces have been transformed into agricultural production space, and the urban living space has expanded significantly. (3) The evolution of production-living-ecological spatial pattern in Northeast China is influenced by the comprehensive effects of land use intensity, temperature, elevation, regional GDP, population density and other factors. Human activities accelerate the evolution of production-living-ecological spatial pattern. ConclusionsThe evolution of production-living-ecological space in Northeast China is influenced by the dual mechanism of "constraint of natural base + dominance of human activities". It is necessary to coordinate the contradictions between ecological protection, agricultural production and urban expansion, and strengthen the management and control of the resilience of territorial space.
