生态系统结构是生态系统的构成要素在空间上和时间上相对有序且稳定的状态。

生态系统结构是生态系统的构成要素，在空间上和时间上相对调整，并且稳定的状态。 人类通过改变生态系统的要素和调整的方式实现对生态系统结构的调整，传统的生态修复工程多采用材料水泥、有机材料，往往会造成生物降解性降低、桐生异质性降低、生态系统生育破坏等。随着回归自然、回归自然意识的增强、仿造自然意识的增强，仿造自然生态生态设计的理念在生态修复中工程的应用全面广泛。 自然自然生态功能自然设计 以中人与自然和谐相处的发展理念，接近自然、模拟自然为手段构建结构合理、完善的自然生态系统结构。，在进行洪排洪水道设计时，要在保证排洪水道行洪与蓄水两方面同时要求的同时，在条件允许的情况下，恢复水道的岸、浅凹岸、滩等，并选择当地凸土的植物和石材、采用护坡，材料护坡，营造贴近自然的，适合动植物生长的生境，维护生态和生物保持平衡。

Ecosystem structure is a relatively orderly and stable state of the elements of ecosystem in space and time. Human beings regulate the structure of the ecosystem by changing the components and patterns of the ecosystem. The traditional ecological restoration projects mostly use concrete, cement, steel and other materials, which often lead to the reduction of biodiversity, landscape heterogeneity, ecosystem damage and other consequences. With the enhancement of people's consciousness of returning to nature and integrating into nature, the concept of imitating natural ecological design is gradually widely used in ecological restoration engineering. Imitating natural ecological design emphasizes the sustainable development concept of harmony between human and nature, and constructs a natural ecosystem structure with reasonable structure and perfect function by means of approaching nature and simulating nature. For example, in the design of flood discharge channel, it is necessary to restore the natural distribution of convex bank, concave bank and shoal of the channel while ensuring the requirements of flood discharge and water storage. Local plants and stones should be selected and natural materials should be used for slope protection to create a habitat close to nature and suitable for the growth of animals and plants and maintain ecological balance and biodiversity.<br>
