【摘要】 通过对珠江三角洲区域绿地在城市化进程中的变化和环境承载力分析,针对本区域的绿地空间格局及其生态功能转型对区域(社区)生态健康的影响,提出农田-农村以及河流是未来生态城市和区域生态安全的战略点和景观纽带的低碳绿地发展思路。并认为对区域绿地的城市化建设应有一种制约机制,而提出低碳概念和建立定性或定量指标也是今后绿地建造的重要标尺。这将有利于城-乡体系的绿地空间的长远生态保护和利用,特别对森林,水源,湿地,农田和村落等生态敏感区尤为重要。更多还原

【Abstract】 With an analysis of the changes and the environmental carrying capacity of regional green spaces in Pearl-River Delta during the urbanization process and a focus on the pattern of regional green spaces and their effects on local ecological system,this article states that farmland-countryside and river corridors are of most strategic values in sustainable development and that they are also the trend of low-carbon green spaces.It argues for establishing a system to restrict the outspread of urban areas into regional greenbelts and puts forward a lowcarbon concept and qualitative index for the development of green spaces in the future.This article provides useful ideas that will be beneficial to the ecological preservation and development of urban-rural green spaces,especially the local forests,water resource,wetlands and agricultural lands.更多还原
