摘要: Studying land use changes and ecological risk assessment in Yongjiang River Basin Zhejiang Province, China, provides theoretical references for optimal configuration of resources maintaining stability ecosystems. Given impacts on landscape patterns the Basin, indexes were constructed used to analyze temporal spatial variation characteristics within different periods. Results show that (1) construction area was increased quickly, while cultivated decreased sharply. A prominent characteristic manifested by transforming forestland into land. The utilized degree continuously. Spatially, northern regions higher than southern eastern western regions. (2) intensified high expanded 893.96 km2. Regions with low relatively risks concentrated whereas mainly Landscapes cities towns at a economic development level are highly sensitive human activities. (3) Transformation is complicated. Land changing from 4.15 times level. There 15 transformation directions among
