As an important part of urban green space, how to effectively guide the improvement of the ecological benefits of residential green space has become one of the important issues in current residential planning. Western countries such as Germany, Sweden, and the United States have successively used the “Green Space Factor” as a tool for ecological assessment, while in China’s settlement planning, there is only one greening rate indicator as a guide. Based on the Green Factor of Seattle, USA, this study used Harbin high-rise residential area as the research object to establish a Green Space Factor assessment tool for Harbin. The evaluation indicators were screened, adjusted and assigned through expert questionnaires. Finally, an evaluation system with five categories and 25 evaluation indicators was established. Subsequent assessments of the ecological benefits of the selected nine high-rise residential areas were evaluated. From the evaluation results, it can be found that the advantages and disadvantages of the ecological benefits of the settlements are directly related to the allocation of the landscape elements in the settlements and have a certain relationship with the greening rate and the volume ratio of the settlements. The settlements with high volume ratio and low greening rate can adjust the landscape elements. The configuration can also achieve high ecological benefits. This study can provide strong support for guiding the construction of green infrastructure in high-rise residential areas in cold cities. |
