Spatial and Temporal Evolution of the Production-Living-Ecological Space in Lianyungang City Lianyun District and Simulation of Carbon Stock Changes in Multi-Scenarios Based on PLUS-Markov-InVEST Model
As the core of the regional human-land relationship system,it is important to explore the spatial and temporal evolution patterns and carbon stock changes in the small-scale high-resolution areas at the county and district level,in order to provide reference for the synergistic effects of the regional produc-tion-living-ecological space to play a better role.This paper analyzes the production-living-ecological space classification system based on land use vector data of Lianyungang City in 2018-2021,and analyzes the pro-duction-living-ecological space classification system based on the dominant function of land use from three aspects of land use quantity,structure,and degree of change.Lianyungang District land use vector data from 2018 to 2021,establish the classification system of the production-living-ecological space based on the dominant function of land use,analyze the land dynamic evolution process of the production-living-ecologi-cal space in terms of changes in the quantity,structure and degree of land use,and select 21 driving factors from the natural and socio-economic dimensions,and use PLUS to analyze the spatial and temporal evolu-tion of the production-living-ecolofical space.The data of 21 driving factors were selected from both natural and socio-economic levels,and the PLUS-Markov-In-VEST model was applied to simulate the land use and analyze the change of carbon stock in 2025 under the scenarios of natural development,economic devel-opment and dual protection of arable land and ecology.The results show that the two scenarios of natural de-velopment and economic development are not conducive to the sustainable development of the region.Only under the scenario of dual protection of arable land and ecology can the production space and living space be reallocated rationally while protecting the ecological space.
