| Our country's urbanization course has accelerated for recent years, thereby it brings on the unbalanced of the ecosystem,the worse of the person residence environment,the lack of the city greenbelt/the lost multiplicity sight/a series of ecosystem problemswhich has gradually become the obstacle of improving the urban environment and residents life quality. City greenbelt system isan important component of the city ecological environment, and the core to maintain the ecological functional of the city. Plants whichare the main component of the city greenbelt system have many ecological function. So the construct of the city greenbelt already has becomean important index judging one cityg development.With important ecological function and social value, the urban road is a key standard measure of urban ecological continuous development. Among that, the landscape patch is a key feature to maintain the function of landscape. The connectivity is not good overall which is closely related to the component of landscape. The tremendous patch is most valuable for the connectivity but the small one is still important. And the valuable patches are mainly found in the mountain, water, village, forest, and everglade etc. And they are primary considered in the layout and protection of urban green space. Based on the research result, while planning the layout, it's better to primary consider to protect the important patches meanwhile think out to build up small patch among the tremendous ones, to make up connectivity corridors, improving the connectivity of the landscape..After the analysis, it proposes multiple types and structures of landscape patches, discusses the ecological meaning of it in the layout of urban road. The amount, size and shape of the patch, the character, amount and proportion of the landscape type, and the distribution of landscape, connectivity of spaces and functionalities between patches are all of the main factors. |
