Functional Evolution of the"Production-Living-Ecological"Space and Its Response to Ecological Security——A Case Study of Shizhu County
Taking Shizhu County in typical mountainous and hilly area as the research area,and ArcGIS software as the platform,this paper constructed the functional structure system of"production-living-ecological"space.The functional transfer matrix,ecological security quality index and ecological contribution rate model of"production-living-ecological"space were used to analyze and study the spatial and temporal distribution characteristics of"production-living-ecological"space and ecological security.The results showed that:during the study period,eco-logical space was absolute dominant in Shizhu County,and the ecological space and living space area showed an overall upward trend,while the production space area showed an overall downward trend.The production space transferred to the ecological space was the largest,and the living space transferred to the ecological space was the smallest.The spatial distribution trend of ecological security was consistent with the change pattern of"produc-tion-living-ecological"space.The comprehensive impact index of dynamic changes in the function of"production-living-ecological"space on ecological security was positive,which was in line with the trend of ecological securi-ty level gradually improving in Shizhu County.
