本文旨在探讨如何使较大生态空间斑块形成闭合区域，在空间属性上保持相对的完整性和单一性，并加以有效保护，使生态空间真正成为城市发展的绿色屏障。从现有文献和同江市“多规合一”实践看，由于历史遗留、追逐利益和监管不力等诸多因素，生态空间甚至核心区域内有耕地和较大面积的生活聚居区挤占生态空间，导致环境质量下降。可通过退耕还林还草工程、迁出生态空间居民工程和加强生物多样性保护工程等路径实现生态空间完整性。与此同时，采取加大对生态空间的保护力度、提高公众对生态空间完整性的认识、建立科学的生态补偿机制及加强中俄生态保护合作等措施加以保护。%The paper tried to research how to maintain the relative integrity and exclusive of big ecological spatial patches, then make them become the green barrier for urban development. By reviewing literatures and practices of multiple planning integration carried out in Tongjiang City, we found that because of the historical legacy, chasing interests and the ineffective supervision, there are some farmlands and living area occupying the core ecological space, where environmental quality is declined. The ecological space integrity can be improved by implementing Green for Grain Project, residents immigration project and biodiversity protection project. We suggested taken steps to protect the ecological space, for example strengthen protection, deepen the understanding, establish scientific and reasonable ecological compensation mechanism, enhancing mutual co-operation on protection of ecological field between China and Russia.
