Zoning of Territorial Space for Ecological Restoration Based on Potential Ecological Background Pattern Framework:A Case Study of the Guangdong-Hong Kong-Macao Greater Bay Area
摘要
Abstract
Ecological restoration zoning is the concept of carrying out ecological restoration scientifically.In existing zoning studies,an effective technical solution is to use ecosystem service supply and ecological security pattern analysis as starting points.These studies have mostly focused on the negative ecological effects of high-intensity human activities and are still essentially focused on at-risk areas.Zoning is used for identification,the potential for effective regional ecological restoration is not considered systematically,and there is insufficient support for the theory and practice of ecological restoration.However,ecological restoration is a product of human society and economic processes of input and output.In addition to accurately identifying ecological risk areas,research on restoration zones should also consider regional ecological protection policies and economic differences to increase investment in environmental protection and improve the effectiveness of ecological protection in a targeted manner.Based on the current paradigm,the spatio-temporal matching of social economy and natural resources is taken into consideration,to realize the optimization of an ecological restoration zoning technical scheme.Taking the Guangdong-Hong Kong-Macao Greater Bay Area as an example,a regional framework for the ecological restoration of land space based on ecological background pattern and potential was constructed.The results show that ecosystem services have declined significantly in the past ten years,and there are areas with good natural resilience and strong support from protection policies.Township as the unit of ecological restoration zoning.1)The ecological maintenance area accounts for 7.7%of the total area,and focus should be on comprehensive improvement to promote economic and ecological sustainability.2)The ecological protection area accounts for 44.5%,and focus should be on protection and stronger policy control.3)The ecological improvement area account for 11.9%,and diversified and continuous maintenance measures should be adopted to strengthen the redundancy of regional ecological network.4)The ecological restoration area accounts for 35.9%,and the priority for restoration should be areas with high natural resilience and policy support,and should mainly comprise long-term restoration projects.The coordinated restoration area has a high natural restoration;however,the policy support is insufficient.Cooperation with higher-level governments or with regional joint governance should be initiated to improve efficiency of the overall restoration in the region.关键词
