【摘要】：近年來,城市高密度發(fā)展推進(jìn)了熱島效應(yīng)的產(chǎn)生,也導(dǎo)致社區(qū)綠化空間不足,而植被作為城市生態(tài)建設(shè)中的主體,對(duì)于調(diào)節(jié)氣溫,緩解熱島效應(yīng)有著極其重要的作用。當(dāng)前建立在傳統(tǒng)二維層面的綠化量并不能真實(shí)反映植被類別及群落分層結(jié)構(gòu)情況所產(chǎn)生的生態(tài)效益。本文則以綠量為切入點(diǎn),主要工作及研究結(jié)論如下:首先,通過遙感數(shù)據(jù)和ENVI平臺(tái),研究了北京市海淀區(qū)綠量空間分布情況,并在海淀區(qū)社區(qū)調(diào)查的基礎(chǔ)上,對(duì)比了環(huán)境條件相似,建筑布局、綠化布局形式不同的7個(gè)高密度社區(qū),最終確定曙光花園社區(qū)為進(jìn)一步植被調(diào)查及熱環(huán)境實(shí)測(cè)工作的樣本社區(qū)。其次,基于實(shí)地調(diào)查和GIS平臺(tái),分析了曙光花園社區(qū)用地功能、空間組織形式、綠量、單位面積的綠量、植被搭配方式的空間分布情況。再次,通過大量實(shí)測(cè)溫濕度數(shù)據(jù),并運(yùn)用GIS的空間插值分析,研究曙光花園社區(qū)夏季不同時(shí)刻的溫度和相對(duì)濕度的空間分布特征。最后,從用地功能、單位面積的綠量以及植被搭配方式三個(gè)層面分別研究了綠量分布差異對(duì)熱環(huán)境的影響規(guī)律。研究發(fā)現(xiàn):綠地?zé)岘h(huán)境會(huì)隨著用地功能的不同呈現(xiàn)出不同的溫濕度差異,曙光花園社區(qū)綠地溫度表現(xiàn)為:防護(hù)綠地商務(wù)綠地公園綠地居住用地,相對(duì)濕度與之相反;在居住用地中,圍合式住宅空間綠地的降溫和增濕效果比分散式空間綠地較好;運(yùn)用Origin函數(shù)軟件,發(fā)現(xiàn)宅間綠地因分散且受建筑陰影影響,其降溫增濕效果與單位面積的綠量無相關(guān)性;中心綠地的單位面積綠量大于1m3/1m2時(shí),與降溫能力顯著相關(guān),當(dāng)單位面積的綠量超過5m3/m2后,降溫能力趨于平緩;增濕效果與單位面積的綠量相關(guān)性不大,而與綠地所處的環(huán)境、位置有關(guān);對(duì)比相同區(qū)域,相同單位面積綠量區(qū)間的喬木型、喬灌草、喬草、喬灌型綠地的降溫增濕效果,發(fā)現(xiàn)喬灌型降溫增濕效果較明顯,且晚間降溫最快;對(duì)于不同綠量比例的綠地,喬木的綠量對(duì)降溫效果影響程度較明顯,對(duì)增濕效果無明顯影響。本次研究也進(jìn)一步證實(shí)了建筑空間組織形式及建筑陰影直接影響著綠地的溫度場格局;社區(qū)內(nèi)采用圍合式集中布局,且形成連續(xù)的規(guī)�；邏K的中心綠地具有良好的降溫增濕能力。
[Abstract]:In recent years, urban high-density development has promoted the generation of heat island effect, which also leads to the lack of community greening space. As the main body of urban ecological construction, vegetation plays an extremely important role in regulating temperature and alleviating heat island effect. At present, the amount of greening established on the traditional two-dimensional level can not truly reflect the ecological benefits of vegetation types and community stratified structure. The main work and conclusions are as follows: first, through remote sensing data and ENVI platform, the spatial distribution of green quantity in Haidian District of Beijing is studied, and based on the community survey in Haidian District, the paper studies the spatial distribution of green quantity in Haidian District. Seven high-density communities with similar environmental conditions, architectural layout and greening layout were compared, and the dawning garden community was determined as the sample community for further vegetation investigation and thermal environment measurement. Secondly, based on field investigation and GIS platform, the spatial distribution of community land use function, spatial organization form, green quantity, green quantity per unit area and vegetation collocation were analyzed. Thirdly, the spatial distribution characteristics of temperature and relative humidity at different times in summer in the community of Shuguang Garden are studied by using a large number of measured temperature and humidity data and spatial interpolation analysis of GIS. Finally, the effects of green quantity distribution on thermal environment were studied from three aspects: land use function, green quantity per unit area and vegetation collocation. The results show that: the thermal environment of green space will show different temperature and humidity with the function of land use. The temperature of community green space in dawning garden is as follows: the green land of commercial green space park is protected, the relative humidity is opposite to it; In the residential land, the cooling and humidifying effect of the enclosed residential space green space is better than that of the decentralized space green space, and by using Origin function software, it is found that the green space between the houses is influenced by the building shadow because of the dispersion. The effect of cooling and humidifying has no correlation with the green quantity per unit area. When the green amount per unit area of central green space is larger than 1m3/1m2, it has a significant correlation with the cooling capacity. When the green amount per unit area exceeds 5m3/m2, the cooling capacity tends to be flat. The effect of humidification is not related to the green quantity per unit area, but to the environment and position of the greenbelt, compared with the cooling and humidifying effect of the same area, the tree type, the tree irrigation grass type and the tree irrigated type green space in the same area. The results showed that the cooling and humidifying effect of Arbor irrigation type was obvious, and the cooling rate was the fastest in the evening, and for the greenbelt with different green ratio, the effect of tree green quantity on the cooling effect was more obvious, but not on the humidification effect. This study further confirmed that the structure of the building space and the shadow of the building directly affect the temperature field pattern of the green space, and the enclosed centralized layout is adopted in the community. And the center green space which forms continuous large-scale patch has good ability of cooling and humidifying.
