城市地价动态监测体系的设立及地价水平分析--以石家庄市住宅用地为例

对城市地价的动态监测主要是通过设立监测体系对地价监测点的监测来实现的．通过对石家庄市住宅用地监测点地价的时空分布分析,监测点地价水平与基准地价、市场交易样点地价进行比较分析及地价趋势预测,为了解和掌握城市内的地价水平、地价动态变化情况和日常地价管理提供决策依据．     

基于AHP法的居住区围墙满意度评价——以福州市为例

选择福州市区的围墙为研究对象,通过对30名专家和250名普通市民进行问卷调查,采用Delphi法和AHP法对居住区围墙满意度进行评价;结果显示:居住区围墙满意度值为2.93,属"基本满意";物质属性满意度值3.16、功能属性满意度值3.02、空间属性满意度值3.20、与环境融合性满意度值2.81,均属于"基本满意";而视觉属性满意度值仅为2.46,属"不太满意";对围墙建设提出了参考建议。     

Research on Uncertainties in Evaluation Indicator System for Ecological Residential Community

In the process of evaluating,the weights of indicators are firstly determined by AHP and Delphi methods:and the values of indicators are normalized by grey correlative coefficient method.A suit of means were put forward,by which a qualitative and quantitative evaluation indicator system suitable for the situation of China and uncertainties can be established.Both idiographic and operable methods and process were presented.Following the principle of elasticity,hiberarchy and maneuversbifity,a three-layer evaluation indicator system was established by AHP in Jiuyi ecological residential community, which includes 5 subsystems and 24 indica-tiors.The weights of indicators are measured by AHP and expert estimate and their best indicators values up to par were determined by fuzzy mathematics and optimization.The whole evaluation indicator system not only has an active and practical effect on estimating ecological residential community,but also guides ecological residential community planning.     

“双碳”目标下寒冷地区城市滨水住区夏季的热环境特征——以天津市为例

 为响应“双碳”政策，进一步明确中国寒冷地区滨水住区夏季热环境特征，基于天津市91个典型滨水住区的Landsat-8遥感影像与空间环境因子，运用相关性分析与多元线性回归方法得到热环境特征。结果表明：面状水体热环境调节作用优于线状水体，住区平均热岛强度差值达1.57℃；住区热环境与建筑密度、滨水距离呈显著正相关，与平均建筑高度、归一化植被指数、周边水面率呈显著负相关，其中归一化植被指数与周边水面率影响权重最高；不同建筑布局住区热环境的影响因子存在差异，点阵式住区平均热岛强度最低，围合式住区最高；当建筑密度小于19.08%，通过减小住区滨水距离、增加周边水面率能有效调节热环境。提出了改善寒冷地区滨水住区热环境的建议。     

Influence of Horizontal Flow on Atrium in High-Rise Residential Building

In this study a 10-storied residential building model was employed to clarify the ventilation charac-teristies of the atrium and the rooms,which were effected by the different forms of lateral openings.The experi-ment was conducted under the combined effect of wind force and thermal buoyancy,and the similarity require-menus were satisfied.The results have shown that the different forms of lateral openings cause the different yen-tilation effect of the building,and also have some certain regularity.The conclusions provide a theoretical foun-dation for how to use the ventilation of atrium better in high-rise residential building.
