Abstract: In order to get an objective and reliable result with public opinion for greening evaluation, this paper took Beijing as study area, collected public information of residents in Beijing with social network. The information reflected the public satisfaction towards their living environments. According to the public satisfaction levels, this paper divided 207 residential districts investigated on the spot into 6 categories. And public desirability of greening landscapes was also investigated. The results showed that the satisfactory characteristics were as follows: Vegetation density, openness and availability of green lands, semi-wide field of vision, landscape designs close to nature, narrow and tortuous paths and water body in the green lands. This result not only reflected those positive environmental characteristics, but also proved that public participation in the designing and evaluation of residential greening is feasible to a certain extent.
