To keep certain number of greater patches through protection and restoration in urban area is meaningful;(2) small greenland patches with diverse structure may promote the heterogeneity of urban landscape, and serve as colonial land and stepping stones for certain populations, and create rich types of habitats and ecological niches. So laying small patches in urban environment is also important. Incorporation of the coarse grain and fine grain, aggregation and outliner of landscape elements may creates better landscape patterns;(3) many literatures have showed that good landscape connectivity benefits the longer persistence of species and the conservation of biodiversity.

大的绿地斑块有多种作用，通过城市地区自然景观斑块的保护或城市绿地的建设，在城市中维持一定的较大规模的绿地斑块是有积极意义的；（2）结构不同的小的绿地斑块可增加城市的景观异质性，为生物提供迁徙地、扩散暂歇地，创造丰富的生境资源和生态位，因此，结合大的绿地斑块的建设，同时布置小的绿地斑块作为补充，粗粒、细粒结合，集聚、分散结合是形成优良绿地景观格局的途径；（3）诸多的文献已显示，好的景观连接性有利于物种持续较长的时间，从而有利于生物多样性的保护。
