武汉市城市内部生态用地时空演变特征研究
Spatiotemporal evolution characteristics of intra-urban ecological land in Wuhan
摘要
Abstract
It is crucial for optimizing the layout of intra-urban ecological land and enhancing the ecological well-being of urban residents to understand the spatiotemporal evolution characteristics of intra-urban ecological land scientifically.Taking the area within the Third Ring Road of Wuhan City as the research area,the major land cover types were identified by high resolution remote sensing images in 2000,2010 and 2020.The evolution of intra-urban ecological land was analyzed in terms of quantitative,spatial landscape pattern by using methods such as land use dynamics and landscape pattern index.The results showed that:(1)The total area of ecological land showed a downward trend from 2000 to 2020,primarily due to reduced cultivated land,while the area of woodland and grassland increased significantly.(2)The decrease of ecological land areas was located in the newly built areas near the Third Ring Road,while the increase of ecological land areas was located in the internally developed areas.(3)The fragmentation of ecological land showed an increasing trend,and there was significantly spatial difference.The increasing fragmentation areas were mainly located in the newly built areas,while the fragmentation within the city's built-up areas decreased in recent 10 years.Economic development,population growth and government policies were the three main aspects resulting in the change of ecological land use patterns.These findings could provide a scientific basis for the optimization and management of ecological land use within urban areas.关键词
