【摘要】：高速的城鎮(zhèn)化建設(shè)引發(fā)很多城市環(huán)境問題,例如熱島效應(yīng),景觀要素的微氣候調(diào)節(jié)上的應(yīng)用逐漸引起學(xué)術(shù)界的關(guān)注。建造屋頂花園成為解決這一問題的主要方法之一。屋頂花園環(huán)境的熱舒適性對城市戶外公共活動空間的發(fā)展具有積極且重要意義。本文選取哈爾濱市工業(yè)大學(xué)第二校區(qū)寒地建筑科學(xué)與工程研究中心三層的屋頂花園,采用實地測量與數(shù)據(jù)對比分析的方法,探討屋頂花園植被樹種與種植方式對熱舒適度的影響,旨在為更好的選擇適宜嚴(yán)寒地域屋頂花園種植的植被樹種提供相關(guān)依據(jù)。首先,相關(guān)基礎(chǔ)研究。明晰哈爾濱市季節(jié)特點(diǎn);對寒地屋頂花園的植被樹種選擇、種植方式、植被綠化形式等多種因素均會對熱舒適度產(chǎn)生一定影響,說明了植被樹種對熱舒適度有調(diào)節(jié)作用。其次,展開實地測量。結(jié)合植被樹種選擇、種植方式、植被綠化形式的典型性,選取屋頂花園的的五個測試點(diǎn)作為實測目標(biāo),篩選出具有代表性的寒地屋頂花園5種常用植被樹種:八寶景天、石竹、金葉榆、紫萼玉簪、青扦云杉;測量時間分別在夏季(8月)和冬季(11月),各為期3天,在早晨8:00~17:00,間隔時間分別為1分鐘和30分鐘;在夏季分別測量五種單株植被樹種的微氣候日變化狀況,冬季測量地被植被的微氣候日變化狀況。測試內(nèi)容主要包括空氣溫度、濕度、風(fēng)速、太陽輻射強(qiáng)度四個微氣候因子,模擬整合出熱舒適度PET指標(biāo)。最后,實測數(shù)據(jù)分析。(1)分析了冬季和夏季兩季屋頂花園中不同植被樹種對微氣候因子中溫度、濕度、風(fēng)速、太陽輻射以及熱舒適度(生理等效溫度PET)的調(diào)節(jié)程度,為冬夏兩季熱舒適度優(yōu)化,提供對應(yīng)的樹種選擇;(2)采用SPSS數(shù)據(jù)系統(tǒng)軟件分析植被樹種樹高、冠幅、冠層密度、樹冠距離等因子和微氣候因子的相關(guān)性,闡釋說明植被樹種生物形態(tài)學(xué)特性與熱舒適度間的緊密聯(lián)系;(3)剖析了夏季哈爾濱屋頂花園植被樹種對微氣候因子中溫度、濕度、風(fēng)速、太陽輻射以及熱舒適度(生理等效溫度PET)的影響調(diào)節(jié)程度,對比了種植不同植被樹種對熱舒適度的影響,以探求對人體舒適度最為適宜的植被樹種。
[Abstract]:The rapid urbanization has caused many urban environmental problems, such as the heat island effect, the application of landscape elements in the microclimate regulation has gradually attracted the attention of the academic community. Building a roof garden is one of the main ways to solve this problem. The thermal comfort of roof garden environment has positive and important significance for the development of urban outdoor public activity space. In this paper, the roof garden on the third floor of the Cold region Architecture Science and Engineering Research Center, the second campus of Harbin University of Technology, is selected, and the method of field measurement and data comparison and analysis is adopted. The effects of tree species and planting methods on thermal comfort of roof garden were discussed in order to provide relevant basis for better selection of vegetation species suitable for roof garden planting in severe cold areas. First of all, related basic research. The seasonal characteristics of Harbin City, the selection of vegetation tree species, planting mode and vegetation greening form of roof garden in cold region will affect the thermal comfort to some extent, which shows that the vegetation species can regulate the thermal comfort degree. Secondly, the field measurement is carried out. Combined with the selection of vegetation tree species, planting methods and typical vegetation greening forms, five test points of roof garden were selected as the measured targets, and five common vegetation species were selected as representative vegetation tree species in the cold region roof garden: Pabaojingtian, Carnation, and so on. The measured time was 3 days in summer (August) and winter (November), and the interval was 1 minute and 30 minutes in the morning at 8: 00 and 17: 00, respectively. The diurnal variation of microclimate of five individual vegetation species was measured in summer and the diurnal variation of microclimate of ground cover vegetation in winter. Four microclimatic factors, air temperature, humidity, wind speed and solar radiation intensity, are included in the test. The thermal comfort PET index is simulated and integrated. Finally, the measured data are analyzed in winter and summer to analyze the adjustment degree of different vegetation species to microclimatic factors, such as temperature, humidity, wind speed, solar radiation and thermal comfort (physiological equivalent temperature PET). In order to optimize the thermal comfort of winter and summer, the corresponding tree species were selected. The SPSS data system was used to analyze the correlation between the tree height, crown width, canopy density, crown distance and microclimatic factors. Explaining the close relationship between Biomorphological characteristics and Thermal comfort of vegetation Tree species. (3) analyzing the effect of vegetation species on temperature, humidity and wind speed in summer in Harbin rooftop garden. The effects of solar radiation and thermal comfort (physiological equivalent temperature PET) on thermal comfort were compared in order to find the most suitable vegetation species for human body comfort.
