Ecological protection and restoration zoning and control of mineral resource-based cities——Taking the main urban area of Anshan as an example
From 2000 to 2020,along with the change of urban development pattern,mineral resource exploitation and other factors,the ecological pattern in the main urban area of Anshan has changed.The existing urban ecological spatial layout couldn't meet the overall requirements for the construction of territorial ecological security.Based on the evaluation results of the importance of ecosystem services and ecological sensitivity,the spatial distribution results of the importance of ecological protection in the study area were obtained with the ecological environment problems and ecological structure characteristics in the main urban area of Anshan as the basic guidance.Based on the spatial distribution results of ecological protection importance,land use types,and main ecological environment problems,the study area was divided into 5 zones,namely strict protection area,key control area,landscape utilization area,optimized coordination area,and core restoration area.According to the leading functions and ecological protection and restoration objectives of each sub-area,specific control and ecological protection and restoration strategies were put forward.
