合理的河流蓝绿空间布局对于提升生态环境、景观效果具有重要作用.大同市近年来通过河道生态治理,6条山水廊道蓝绿空间格局初步形成,但仍存在御河、十里河、南洋河、浑河、壶流河、唐河等河流蓝绿空间韧性不足、蓝绿空间布局缺乏系统统筹、城乡蓝绿空间割裂等问题.以蓝绿空间存在问题为导向,提出"提升蓝绿空间韧性、协调山水绿城田关系、增强城乡蓝绿连接"等蓝绿空间融合策略,以期为大同市河流生态治理提供借鉴和参考.

实施乡村振兴战略,要坚持生态优先,绿色发展.现主要从乡村振兴战略背景、乡村景观资源分类、乡村生态景观类型等方面进行阐述,凸显"一镇一风情"、"一村一风景"的特色主题,重点对浙江省天台县水美乡村生态景观建设的路径和方法进行分析,促进水美乡村建设,改善农村人居环境,提高当地村民收入及生活幸福感.

生态敏感性分析是生态景观规划的重要依据.为促进生态建设与环境保护,优化用地布局,运用GIS(地理信息系统)分析技术,结合土地利用类型数据,构建了生态敏感性分析指标体系,采用层次分析法确定要素指标权重,并以深圳市宝安区碧道建设工程为例,综合分析和评价了宝安区碧道的生态敏感性及其空间分布状况.结果表明:最高敏感性和高敏感性区域主要位于水系廊道两侧及部分植被覆盖较好区域,该区生态敏感且脆弱,最易受到外界环境的影响而发生变化,导致生态价值发生较大下降.

By taking Pingshanhe River in Penglai City as a study case，the eco-service functions of different areas in the riparian zone are positioned，and then the spatial system structure of the riparian zone is analyzed and the eco-restoration method of the urban riparian zone is expatiated as well. The establishments of both the riparian buffer zone and its functions are taken as the restoration objective，so as to restore the operation system of the self-eco-system structure of the buffer zone. Through restoring the habitats and the community structure as well as integratedly restoring the function of the landscape system with three-level restoration mode in the riparian buffer zone，both the width and the structural system of the riparian buffer zone suitable for urban river are proposed，thus the relevant idea and technical support are provided for the final river eco-restoration scheme. This is helpful to realize the self-adjustment and sustainable development of the eco-landscape system in the riparian zone，and then makes an organic link between the two different environments of both the land and the water for promoting the harmonious co-existence between human and nature
