基于景观格局的左江流域景观生态风险评价
Landscape Ecological Risk Assessment of Zuojiang River Basin Based on Landscape Pattern
摘要
Abstract
In order to ensure the health and stability of the ecosystem in the Zuojiang River basin and improve the level of land use planning and management,the land use data for the three periods of 2000,2010,and 2020 are used as the basis,using landscape disturbance index,landscape vulnerability index,and landscape loss index as evaluation indicators,a landscape ecological risk assessment model is constructed to evaluate the landscape ecological risk in the Zuojiang River basin from 2000 to 2020.Research has shown that the landscape ecological risk index in the Zuojiang River basin is influenced by natural factors and human activities in spatial distribution,with the northwest region significantly higher than the central and southern regions.In 2020,the area of ecological risk zones below moderate ecological risk was 1 745 000 hm2,accounting for 76.7%of the study area.The land use types in the research area are mainly cultivated land and forest land,in 2020,the total area of forest land and cultivated land was 1 866 711.96 hm2,accounting for 92.9%of the research area.As a region with frequent human activities,the landscape pattern changes in the Zuojiang River basin are closely related to human activities.关键词
