粤港澳大湾区景观格局演变及其对生态系统服务价值影响
Spatiotemporal variation of landscape pattern and the impacts on ecosystem service in the Guangdong-Hong Kong-Macao Greater Bay Area
摘要
Abstract
Rapid urbanization has been one of the primary drivers of ecosystems change in the Guangdong-Hong Kong-Macao Bay Area(the GBA).As the leading pole of China's future economic development,the understanding of spatiotemporal variation of landscape pattern in the GBA is of great significance to optimize regional land use and to prevent and control the ecological risks of urbanization.Based on land use and land cover(LULC)data for the years 2000,2005,2010,2015 and 2020,this study analyzed the spatiotemporal variation of landscape pattern during 2000-2020,and further explored the relationship between landscape variation and ecosystem service.The results indicated that:(1)Forest,farmland and urban land were the main ecosystem types in the GBA,the percentage of grassland,shrub and unutilized land were small.(2)From 2000 to 2020,the area of urban land was increased,while others were decreased,and the growth in urban land areas mainly came from the conversion of surrounding farmland and forest.(3)Landscape fragmentation and connectivity were fluctuated from 2000 to 2015,but the degree of landscape fragmentation decreased and connectivity increased at both patch level and landscape level.(4)PD,SHDI were all negatively correlated with ecosystem service,while significantly positive relationship was found between AI and ecosystem service(P<0.01),namely enhancing the integrity,connectivity and aggregation of landscape may contributes to the improvement of ecosystem services.关键词
