The composite mean of the five residential area afforest landscape from big to small is:HengMaoGuoJiaHuaCheng>ShuiXieHuaDu>ZiJinCheng>LanShuiJiaQi>TianJiJunYuan.Hen gMaoGuoJiaHuaCheng and ShuiXieHuaDu's landscape benefit evaluation comprehensive average was between 7.23-7.25,as "good", ZiJinCheng and LanShuiJiaQi's comprehensive average was between 6.81-6.83,as for "preferably", TianJiJunYuan'scomprehensive average was lower than 6.50,as for "bad".Mandscape benefit's valuation basic according to the high, medium and low 3 class in turn decrease.(3) 3 types of residential area Landscape Benefit average score basically ranking: residential area of public green space> green space next to the building> road green space.

Comprehensive evaluation of road green space in the average scores were basically between 6.1～6.8, were as follows:Hengmaoguojihuacheng>Shuixiehuadu> Zijincheng>Lanshuijiaqi>Tianjijunyuan.
