选择重庆市都市区7个人工湖作
为研究对象,于2 01 2年8、9月采用流动观
测与固定观测相结合的方法进行观测,
并对观测数据进行同时性修订后,采用多
元线性回归方法,建立空气温度(T A)、
湿度(H A)与水体周长(P)、形状指数
(L S I)、水体周边地表温度(T S)以及与
水体距离(D)之间关系统计模型,温度
模型为:TA=18.539+0.3 0 6TS+0.854L SI+
0.0 03D+0.0 01P;湿度模型为H A=75.6 4-
1.027TS+10.970LSI+0.009D-0.003P。模型
分析结果显示:(1)在水体面积相同的情况
下,形状指数小的水体对周围空气降温效果
更明显;(2)植被相对于铺装地表对水体
周围空气有明显降温效果,改善下垫面性质
可以有效改善水体周围空气热环境。本模
型为城市水体景观规划与建设,改善城市人
居环境质量提供了科学依据。 |

Research on the Effects of Artificial Lakes on the Thermal and Humidity Environment in ChongqingMetropolitan |

Abstract: |
Artificial lakes in the city play important roles in the improvement of urban
thermal and humidity conditions. The temperature and humidity models are established,
containing parameters including lake perimeters, area, shape index and distance based
on the actual field survey of seven lakes by mobile observation and fixed observation
in Chongqing Metropolitan in August and September of 2012. The models indicate that
the lake shape index strongly affects temperature. The smaller the lake shape index is,
the lower the temperature surrounding the water is, with the same area. The vegetation
can effectively lower the temperature relating to the pavement, and thus improving the
underlying surface can improve the thermal conditions surrounding the water. |
