中国当前的快速城市化、工业化以及扩张式的城市建设模式导致城市所在区域产生大量残存斑块，其中既包括极度破碎的原有斑块又包含城市生产代谢而成的新生斑块，尤以自然生境斑块更为明显。这些残存斑块对城市生态系统具有保持生物多样性、保护乡土物种、提供生态服务、盘活土地资源、传承地域特色、塑造城市形象、改善生态环境等重要的潜在的功能。因此课题的研究必要而迫切。.课题基于城市残存斑块的生态调查与当前城市化的特征属性研究，界定城市残存斑块的内涵、外延、类型、特征以及影响因子，解析城市残存斑块破碎化的过程及其与人工干扰度的关系，从宏观、中观、微观三个尺度，从生态规划的顶层总体修复、全生命周期管理的过程修复、适度干扰的底层生态工程节点修复三个层级，从理论集成指导与技术修复保障两个层面，基于自然的持续共生、经济的成本控制、社会的公众参与三个维度，修复并激活城市残存斑块，为城市生态文明建设与持续发展提供技术支持。

The rapid urbanization, industrialization and expansion of urban construction led to a large amount of the remaining patches in the city where the plaque, which includes both the extreme fragmentation of the original plaque and fresh one because of the urban production metabolism, especially natural habitat patches are more obvious. The remaining patches of urban ecosystems are potential to maintain biodiversity, protect native species, provide ecological services, Revitalize the land resources, inherit the local culture, shape the city's image, and improve the ecological environment. Therefore the research is necessary and urgent. .Based on the ecological survey of urban remaining plaque and the contemporary urbanization characteristic, to define connotation of the urban residual plaque, extension, types, characteristics and impact factors, evaluate the fragmentation process of urban remaining patches and the relationship with artificial interference. And to repair and activate the urban remaining patches, from the macro, meso and microscopic three scales, based on three layers of the overall top restoration of eco-planning, process repair of lifecycle management, node restoration of eco-project underlying moderate disturbance, the two levels of integrated theory guidance and technical guarantee, and three dimensions of the continuous nature, cost -control economy, civil society participation, which is the way of urban ecological civilization and sustainable development .
