Study on the Microclimate Effect of Water Body Layout Factors on Campus Squares

Abstract

Quantifying the water layout factors in a campus square helps to lay out water bodies more scientifically and utilize the microclimate effect to alleviate the heat and humidity of campus squares in summer. The West Gate Square of Fujian Agriculture and Forestry University in China has been used as the primary theoretical model, and the landscape pattern index from landscape ecology has been used to quantify the scale, shape, and dispersion of water bodies. Consider the typical weather, the summer solstice, as the experiment time. The relationship between the water body layout factors and cooling effect, the humidification effect, and the wind speed is clarified from both temporal and spatial perspectives. The data were analyzed with ENVI-met and Arcgis software. Then, the optimum campus square water body layout mode was concluded. The results show that: (1) The scale, dispersion, and shape of the water body has a significant effect on the campus temperature and humidity, while the effect on wind speed is not significant. (2) From the cooling and humidifying effect, the ranking of the regulating ability of the water body layout factors is scale > shape > dispersion; the ranking of the influence range is shape > scale > dispersion. (3) When the boundary of the square is determined, the optimum water body layout mode is that the water body area accounts for 36% of the total square area. The shape of the water body is concentrated and not dispersed square. When the water body layout is determined, the optimum layout mode of the boundary is length:width = 1:2.

Research on Microclimate-Suitable Spatial Patterns of Waterfront Settlements in Summer: A Case Study of the Nan Lake Area in Wuhan, China

“…In order to quantitatively analyze the effects of different combinations of factors on the thermal and humid environments of waterfront building areas, in this study, based on their same LFs, horizontal (parallel to the riverbank direction Y) and vertical (perpendicular to the riverbank direction X) directions at a level of 1.5 m above the ground in the study region's waterfront building area were used. Sampling points were selected from ventilation corridors and building bypass zones with characteristics representative of the flow field, and the average values at the height of pedestrians in the settlements were compared and analyzed as an analytical index [43,47,48]. The specific horizontal and vertical internal locations are shown in Figure 11, marked by short red dashed lines.…”

Investigating the Impact of Large Lakes on Local Precipitation: Case Study of Lake Urmia, Iran

“…While our study primarily focuses on understanding how Lake Urmia influences local precipitation, it is crucial to consider broader research on how water bodies affect regional climate dynamics. While studies have extensively explored the impact of water bodies on temperature, evaporation, and humidity (see, for example, [31,52,53]), there is a noticeable gap in understanding their influence on precipitation patterns. This gap is particularly significant given the pressing concerns surrounding water management, especially in arid and semi-arid regions facing heightened water stress due to factors like climate change.…”

Study on the Microclimatic Effects of Plant-Enclosure Conditions and Water–Green Space Ratio on Urban Waterfront Spaces in Summer

“…According to the tree height, morphology, and leaf area index of 100 common trees in Fuzhou City, we set the simulated tree species with a tree height of 10 m, umbrella-like morphology, and leaf area index of 3.95 [31]. According to the research results of the previous researchers [32], the green space of waterfront space should account for 35%~75% of the total area of waterfront; the optimal ratio of trees, shrubs, and grasses in the green space of waterfront is 2:2:1; and the height of closed spaces should not be more than 1/2 of the width of the site.…”
