Identification of key areas for ecological restoration of territorial space based on ecological security pattern analysis:A case study of the Taihu Lake city cluster
摘要
Abstract
The identification of key areas for ecological restoration of national land space based on the ecological security pattern is an important way to balance environmental protection and social development in the new era.With the Taihu Lake city cluster as the study area,we identified the ecological source from both structural and functional aspects,and used the minimum cumulative resistance model to identify the ecological corridors on the basis of constructing the resistance surface.Coupled the landscape ecological risk evaluation,we determined the appropriate width of each ecological corridor in the study area,identified the key restoration zones through the cir-cuit theory.Then,we constructed the ecological security pattern of"six zones and four belts"and controlled by zoning.The results showed that the 32 ecological source areas in the Taihu Lake city cluster presented a spatial pat-tern of"more in the east and less in the west-mountains and lakes are connected"and 70 ecological corridors were concentrated in the west and the center.The suitable width of most of the ecological corridors was 1500-2000 m.The ecological restoration zones of the national land space were concentrated in the eastern part of the Lake Taihu,Changxing County,and Liyang City.According to the characteristics of the study area and the actual situation of the restoration area,we proposed specific protection and restoration measures,such as protecting the core ecological source,optimizing and restoring the important corridors,and reasonably planning land use of the ecological pinch points and obstacle points.关键词
