摘要
基于人类干扰评估和生态网络构建,识别粤港澳大湾区国土空间生态修复区域,划定生态源地修复区、生态廊道修复区和踏脚石修复区,提出国土空间生态保护与修复策略。结果表明:1)湾区人类活动对生态环境干扰强度高、影响范围广,高干扰和较高干扰区域占湾区总面积的48.65%,集中分布于湾区中部;2)湾区生态网络整体呈现“两横四纵”的特征,包括北部连绵山体生态屏障、南部近岸海域生态防护带、东部和西部陆域廊道以及中部水域廊道;3)湾区国土空间生态修复区包括生态源地4687.42 km^(2),生态廊道1362.71 km,踏脚石833.82 km^(2),主要分布于肇庆市、惠州市、江门市,从生态网络功能与结构完整的角度,提出国土空间生态修复策略;4)湾区亟待突破区域本位主义理念,凝聚国土空间生态修复协同处置的共识,组建跨域协同治理机构,主导跨区域国土空间生态修复工作。
Territorial space ecological restoration has become a significant strategy for the construction of China's ecological civilization.It is also an important strategic task related to national ecological security and human wellbeing.The continuous expansion of space in urban agglomerations and the high-intensity development of cities have exacerbated the fragmentation of natural landscapes.The ecological security of urban agglomerations and the ecological restoration of territorial spaces have become key issues of common concern to the government and scholars.Currently,the research on ecological restoration of territorial space mostly focuses on the identification of ecological restoration areas based on the key components of ecological security patterns and rarely discusses the coordinated protection and restoration of urban agglomerations by combining the ecological security patterns with human activities.It is particularly necessary to identify the ecological restoration areas and build a technical paradigm for ecological protection and territorial space restoration that can provide a basic support for the ecological integration,construction,and sustainable development of urban agglomerations.Based on ecological network construction and human disturbance assessment,this study diagnoses the territorial space ecological restoration areas of Guangdong-Hong Kong-Macao Greater Bay Area and proposes ecological protection and restoration strategies for the territorial space ecological source restoration area,ecological corridor restoration area,and stepping stone restoration area.The results showed that:(1)Human activities in the Guangdong-Hong Kong-Macao Greater Bay Area had high interference intensities and a wide impact on the ecological environment;areas with high and relatively high interference accounted for 48.65%of the total area,mainly concentrated in the central part of the Greater Bay Area.(2)The ecological network of Guangdong-Hong Kong-Macao Greater Bay Area presented a relatively stable characteristic patt
