【摘要】：在中國(guó)各大城市,城市商業(yè)步行街已成為人們?nèi)粘Ｉ畹闹行�。隨著生活質(zhì)量不斷的提高,人們迫切需要一個(gè)舒適的外部購(gòu)物環(huán)境,商業(yè)步行街不僅為市民提供了購(gòu)物場(chǎng)所,同時(shí)也是人們游憩休閑的地方。無(wú)論從購(gòu)物者還是步行街的工作人員,都希望能有一個(gè)良好的步行街環(huán)境。步行街不再是單純的購(gòu)物場(chǎng)所,同時(shí)也是市民休閑、娛樂(lè)、乘涼、觀(guān)景的公共空間。迄今為止,重慶商業(yè)步行街大多是以硬質(zhì)鋪裝為主,綠量不足。為了研究重慶市商業(yè)步行街植物綠化的微氣候特征,本文選取了重慶市最具人氣的5條商業(yè)步行街：渝中區(qū)解放碑商業(yè)步行街、沙坪壩三峽廣場(chǎng)商業(yè)步行街、江北觀(guān)音橋商業(yè)步行街、楊家坪商業(yè)步行街、南坪商業(yè)步行街進(jìn)行觀(guān)測(cè)研究,這5條步行街都是對(duì)應(yīng)行政區(qū)的經(jīng)濟(jì)中心,且它們都有一定年限、植物長(zhǎng)勢(shì)良好、相互間距離跨度較大。將選取的5條步行街作為研究對(duì)象進(jìn)行實(shí)地微氣候觀(guān)測(cè),同時(shí)測(cè)量計(jì)算出植物綠量,建立步行街植物綠量與步行街的平均溫度、濕度的相關(guān)性分析,得出重慶市步行街植物綠化的合理指標(biāo)。根據(jù)多次實(shí)地調(diào)查,將5條商業(yè)步行街分別有規(guī)律地選出植物多、中、少的樣區(qū)3個(gè),每個(gè)樣區(qū)面積20m×20m,5條步行街共15個(gè)樣區(qū)。在使用香港�，敂�(shù)字溫濕度計(jì)AR867的條件下,分別對(duì)每個(gè)樣區(qū)進(jìn)行溫度(T)和濕度(H)的觀(guān)測(cè),同時(shí)觀(guān)測(cè)每個(gè)樣區(qū)附近純硬質(zhì)場(chǎng)地的溫度(t)和濕度(h)作為對(duì)照值,每個(gè)樣區(qū)與其附近純硬質(zhì)場(chǎng)地同一時(shí)間相對(duì)應(yīng)的溫濕度相減得降溫效果△T=T-t與增濕效果△H=H-h；再測(cè)量得到每個(gè)樣區(qū)植物的綠量(S)；分別做降溫效果與植物綠量的函數(shù)圖像△T/S、增濕效果與植物綠量的函數(shù)圖像△H/S；根據(jù)各個(gè)函數(shù)圖像研究溫濕度與植物綠量的相關(guān)性,從而得到一定范圍內(nèi)最優(yōu)的植物綠量。研究表明,重慶市商業(yè)步行街微氣候與植物綠量有著顯著的相關(guān)關(guān)系,而與步行街喬木綠量的關(guān)系最為密切。在20m×20m的范圍內(nèi),當(dāng)植物綠量到達(dá)750m3～900m3時(shí),植物的降溫效果到達(dá)最佳；當(dāng)植物綠量到達(dá)800m3時(shí),植物的增濕效果達(dá)到最佳。通過(guò)計(jì)算,要到達(dá)溫濕度效果都最佳,而又最大限度的節(jié)約用地(超過(guò)最佳閥值,隨著綠量的大幅增加,植物降溫增濕的效果只會(huì)較平緩的增加,所以大幅增加的綠量只會(huì)占用更多步行街面積,而對(duì)微氣候卻沒(méi)有太大的改觀(guān)),那么重慶市商業(yè)步行街植物三維綠量與步行街面積在數(shù)值上的比值應(yīng)為2：1。在滿(mǎn)足三維綠量的條件下,充分利用步行街的光照、陰影、通風(fēng)、防風(fēng)來(lái)布置植物,將使步行街微氣候的改善起到事半功倍的效果。通過(guò)對(duì)觀(guān)音橋步行街的實(shí)例研究,可以驗(yàn)證運(yùn)用植物綠量來(lái)改善步行街微氣候環(huán)境的可行性,而且也可以使步行街的景觀(guān)更加的優(yōu)美,并為今后重慶市商業(yè)步行街的打造以及改造起到借鑒作用。
[Abstract]:In the major cities of China, the city commercial pedestrian street has become the center of people's daily life. With the continuous improvement of the quality of life, people urgently need a comfortable external shopping environment. The commercial pedestrian street not only provides shopping places for citizens, but also is a place for people to relax. Whether shoppers or pedestrian workers, they want to have a good pedestrian street environment. Pedestrian street is no longer a simple shopping place, but also a public space for citizens to relax, entertain, cool and view. Up to now, most of the commercial pedestrian streets in Chongqing are hard-paved, the green volume is insufficient. In order to study the microclimatic characteristics of plant greening in commercial pedestrian street in Chongqing, this paper selects five most popular commercial pedestrian streets in Chongqing: Jiefang Bei Commercial pedestrian Street in Yuzhong District, Commercial pedestrian Street in three Gorges Square in Shapingba. Jiangbei Guanyinqiao Commercial pedestrian Street, Yangjiaping Commercial pedestrian Street, Nanping Commercial pedestrian Street for observation and research, these five pedestrian streets are the economic centers of the corresponding administrative region, and they all have a certain number of years, and the plants are growing well. The distance between each other has a long span. Five pedestrian streets were selected as the research objects to observe the field microclimate, and the plant green quantity was measured and calculated, and the correlation analysis between the plant green quantity and the average temperature and humidity of pedestrian street was established. Get the reasonable index of plant greening in Chongqing pedestrian street. According to many field investigations, the five commercial pedestrian streets were selected from 15 sample areas, each with a sample area of 20 m 脳 20 m, and 3 sample areas with more, medium and less plants. Under the condition of the Hong Kong Sima digital thermometer AR867, the temperature (T) and the humidity (H) of each sample area are observed respectively, and the temperature and humidity of the pure rigid site near each sample area are also observed as the control values. In each sample area, the temperature and humidity corresponding to the same time of the pure rigid site nearby decrease the temperature and humidity to get the cooling effect TTT-t and the humidification effect, the green quantity of the plants in each sample area is measured and the function of the cooling effect and the green quantity of the plant is made respectively. Image T / S, function image of humidification effect and plant green quantity; study the correlation between temperature and humidity and plant green quantity according to each function image. The optimum plant green quantity is obtained in a certain range. The results show that the microclimate of commercial pedestrian street in Chongqing has a significant correlation with the green quantity of plant, but it is most closely related to the green quantity of Arbor in pedestrian street. In the range of 20m 脳 20m, when the green amount of plant reaches 750m3~900m3, the cooling effect of plant reaches the best, and when the green quantity of plant reaches 800m3, the humidification effect of plant reaches the best. By calculation, the effect of temperature and humidity is the best, and the maximum saving of land (above the optimum threshold, with the large increase of green amount, the effect of plant cooling and humidifying will only increase slightly, So the large increase in green volume will only occupy more pedestrian street area, but the microclimate is not much improved, then the value ratio of plant green volume to pedestrian street area in Chongqing commercial pedestrian street should be 2: 1. Under the condition of satisfying the three dimensional green quantity, it is necessary to make full use of the light, shadow, ventilation and windbreak of the pedestrian street to arrange the plants, which will improve the microclimate of the pedestrian street with twice the result with half the effort. Through the case study of Guanyinqiao pedestrian street, we can verify the feasibility of using plant green quantity to improve the microclimate environment of pedestrian street, and can also make the landscape of pedestrian street more beautiful. And for the future building and transformation of commercial pedestrian streets in Chongqing play a reference role.
