"三生空间"视角下贵州省景观生态安全评价及其耦合特征分析
Evaluation of Landscape Ecological Security and Its Coupling Characteristics Analysis in Guizhou Province from the Perspective of Production-Living-Ecology Space
摘要
Abstract
[Objective]The aim of this study is to explore the evolution of landscape ecological security pattern in karst ecologically fragile areas,which is of guiding significance for the construction of ecological civiliza-tion and ecological risk prevention and control in karst regions.[Methods]Guizhou Province was taken as the research object.From the perspective of production-living-ecology space,based on the theory of landscape ecology and with the help of coupling coordination model,the spatiotemporal variation mechanism and cou-pling coordination characteristics of landscape ecological security in Guizhou Province in the past 20 years were analyzed.[Results](1)From 2000 to 2020,The ecological space of forest land in Guizhou Province was dominant,accounting for more than 53％of the total land space,and the rapid growth of industrial produc-tion and urban living land led to the expansion of urban and rural living space and crowded out agricultural production and forest land ecological space.(2)From 2000 to 2020,the overall landscape ecological security of Guizhou Province was in a good development,and the overall level of landscape ecological security in the south was better than that in the northern region.(3)The Moran's I values of landscape ecological security in Guizhou Province from 2000 to 2020 were 0.340,0.400 and 0.414,respectively,with significant spatial correlations,and the values of'high-high level'and'low-low level'were the main spatial agglomeration patterns,and the local spatial autocorrelation distribution pattern was consistent with the distribution of landscape ecological security.(4)The coupling and coordination level of ecological security of'production-life-ecology'spatial landscape in Guizhou Province was good,and it showed the distribution characteristics of'high level in the west and low level in the east,high level in the north and low level in the south'in space.[Conclusion]The rapid advancement of human economic activities and urbanization will change the regional land use pattern,thereby affecting the regional landscape ecological security and coupling coordination,so it is necessary to optimize the spatial pattern of regional production-life-ecology,improve the efficiency of land resource use,and promote the ecological security construction and sustainable development of land resources in Guizhou Province.关键词
