Surface Thermal Environment and Water Temperature Regulation of Rapidly Growing Small and Medium-sized Cities-Exemplified by Binzhou City of Shandong Province
[Objective] This study investigated the surface thermal environment and water temperature regulation of Binzhou City
and its influencing factors as well
and to provide scientific basis for urban layout planning of water.[Methods] Using Landsat image of 2009 and 2014 years
Mono-Window Algorithm was used to reverse the surface temperature and to analyze the surface temperature distribution characteristics of different land types
and to analyze the regulation effect and the influencing factors of water body temperature by laying temperature points on the temperature line and the water characteristic statistics.[Results] ① In summer and winter
building land had the highest temperature than cultivated land
woodland and water body had in terms of the average thermal grade. ② The temperature regulation effect by waterbody showed strong non-linear relation with the distance from it. ③ Large area water body was observed having better cooling effect. As water area is the same
temperature regulated area by small but many water bodies was larger than that of single large water bodies had. ④ The proportional increase of non-building land around the water body increased the range of water cooling. ⑤ A small water body having longer circumference as compared with the large one
and the range of water cooling is proportionally greater.[Conclusion] The relationship between temperature regulation function and distance of Binzhou water body showed a strong non-linear relationship. The cool effect was affected by the proportion of water body
the complexity of boundary and the surrounding land.
