A probe to the ecological space zoning control at multiple scales in hilly areas of central-south Shandong
Ecological space is an important vehicle for sustaining improved ecosystem services,and the scientific and precise delineation of ecological space zoning is of great significance for ecological protection and restoration.Taking the hilly areas of central-south Shandong as an example,and according to the complex ecosystem theory,five socio-economic indicators and nine natural indicators are used to systematically evaluate the socio-economic and natural characteristics of the ecological space in the hilly areas of central-south Shandong,and the differences in zoning at the grid,town,and topographic scales are explored through the self-organized mapping algorithm to determine the zoning scheme and propose the control strategy by combining the zoning characteristics and the main factors of the zoning.The results reveal that;1)There are urban core recreational zones,mountain-hilly ecological protection zones,and composite coordinated development zones on all three scales,and within the same zoning area,the differences in the characteristics of the main indicators among the three scales are relatively small.2)The town and the topographic scales are advantageous in the urban-rural and high-elevation zoning areas.3)With the grid scale as the basis,and the town and topographic scales as the supplements,the final zoning areas are the urban core recreational zones,urban-suburban ecological restoration zones,urban-rural transition safeguard zones,farmland conservation zones,moderately intervention-protected zones,mountain-hilly ecological protection zones,mountain-hilly ecological restoration zones,and composite coordinated development zones,and the management and control strategies for each area are determined.Based on the geographical characteristics of the hilly areas,and by exploring cross-scale ecological space zoning schemes,this method can effectively guide ecological space zoning and management,thereby provide decisive decision-making support for devising management strategies.
