摘要
This study analyzed the microclimate factors and human comfort index of the inner and outer Fokienia hodginsii forests and of a city square.The results showed that:① In terms of the average daily temperature,the inner and outer forests and the city square ranked as follows: square > outer forest > inner forest.The temperature of the inner forest was 8.21–11.73℃ lower than that of the city square,and the temperature of the outer forest was 7.41–10.34℃ lower than that of the city square.The inner forest was cooled by 24.21% and 1.37% respectively than the outer forest and the city square.② In terms of the average daily relative humidity,the inner and outer forests and the city square ranked as follows: square < outer forest < inner forest.The average daily relative humidity of the inner forest,the outer forest,and the city square was 68.57,84.91,and 88.27,respectively.③ In terms of the average daily wind speed,the inner and outer forests and the city square ranked as: square > outer forest > inner forest.Their daily variation ranges were 0–0.75,0.18–0.43,and 0.12–0.31 m/s,respectively.④ In terms of the daily average illumination intensity,the inner and outer forests and the square ranked as: square > outer forest > inner forest.Their average daily illumination intensities were 371.68,4,582.01,and 17,641.63 lux,respectively.
This study analyzed the microclimate factors and human comfort index of the inner and outer Fokienia hodginsii forests and of a city square.The results showed that:(1) In terms of the average daily temperature, the inner and outer forests and the city square ranked as follows: square > outer forest > inner forest.The temperature of the inner forest was 8.21–11.73 ℃ lower than that of the city square, and the temperature of the outer forest was 7.41–10.34 ℃ lower than that of the city square.The inner forest was cooled by 24.21% and 1.37% respectively than the outer forest and the city square.(2) In terms of the average daily relative humidity, the inner and outer forests and the city square ranked as follows: square < outer forest < inner forest.The average daily relative humidity of the inner forest, the outer forest, and the city square was 68.57, 84.91, and 88.27, respectively.(3) In terms of the average daily wind speed, the inner and outer forests and the city square ranked as: square > outer forest > inner forest.Their daily variation ranges were 0–0.75, 0.18–0.43, and 0.12–0.31 m/s, respectively.(4) In terms of the daily average illumination intensity, the inner and outer forests and the square ranked as: square > outer forest > inner forest.Their average daily illumination intensities were 371.68, 4,582.01, and 17,641.63 lux, respectively.
