摘要
生态网络的规划与建设是保障城市生态空间安全的重要措施,对维持城市生态系统正常运转和生物多样性的保护具有重要意义.近年来,广州市的生态文明建设进步较大,依托"三面环山,一面临海,树状水系"的自然格局,在市内维育9大重要生态片区,构建"三纵五横多廊"的生态网络体系.同时根据生态廊道的功能作用,划分为区域、市域、绿道三个层次的生态廊道.三个层次的生态廊道互相连通,共同形成立体化的生态网络.建设方面以生态网络的源地斑块、生态廊道等就地保护提升为主,通过征地建设修复关键处的源地和廊道为辅,进而完善全市的生态网络.
The planning and construction of ecological network is an important measure to ensure the safety of urban ecological space.Thus it is of great signi cance to maintain the normal functioning of urban ecological system and the protection of biodiversity.In recent years,Guangzhou has made great progress in ecological civilization construction.Relying on the natural pattern of"three sides surrounded by mountains,one side facing the sea and tree-like water system",Guangzhou has built an ecological network system of"three vertical and ve horizontal corridors".According to the function of ecological corridor,it is divided into three levels:regional,municipal and greenway levels.Three levels of ecological corridors are connected with each other to form a three-dimensional ecological network.At the construction side-this paper suggests that to improve the ecological network of the city,the local protection of ecological network patches and ecological corridors should be paid attention to,supplemented by the in-situ conservation and reparation of the source areas and corridors in key areas of land.
