“…These variations may be primarily to vegetation such as lawns or trees often found around the built structures in these UFZs, and the UFZs usually have more complexity or connectivity with surrounding landscapes. Water areas have the "thermostat effects" in comparison to surrounding building materials and serve as cool islands in urban regions during the summer [9,34]. However, water areas were observed to have moderate LST variation in this study.…”

a b s t r a c tThe urban functional zone (UFZ) is the basic unit of urban planning, which is defined as an area of similar social and economic functions. Despite the importance of UFZs, the stability of their annual temperature between winter and summer has seldom been investigated. With an understanding of the thermal impacts that planning decisions can have, it is essential to know how UFZs can be designed to regulate temperatures in the urban environment. 690 UFZs were identified using ALOS images in 2009 in Beijing. Land surface temperature (LST) was extracted from daytime Landsat TM (2002) and ASTER (2009) images. The regional LST variation of 31 district-sized sub-regions was correlated to the types of UFZs in the region and structural features of the region such as area, size, diversity, complexity and connectivity. Results showed that: (1) UFZ types, in order from highest to lowest LST variation, were commercial, campus, high density residential, water, recreational, low density residential, road, preservation, and agricultural zones; (2) the regional LST variation was positively correlated with the area of campus, commercial, high density residential, water, and road zones, but negatively correlated with the area of agricultural and low density residential zones; (3) increased connectivity and complexity decreased regional LST variations. The results indicated that the stability of annual temperatures was determined not only by the UFZ type and size but also by the connectivity and complexity. These results are clearly useful and essential pieces of information that can be applied in urban planning to improve climate adaptability.Crown

“…The resident population of Beijing reached 20.69 million in 2012 (Wang et al, 2014). Rapid urbanization and city expansion resulted in significant UHI effects, particularly during the summer (Ding and Shi, 2013;Kuang et al, 2015;Li et al, 2012;Sun and Chen, 2012;Peng et al, 2016). The UHI intensity in Beijing has increased at a rate of 0.031°C per year (Yu et al, 2005).…”

“…The spatial variation of UHI from city center to outskirts is particularly significant in large metropolitan areas (Kuang et al, 2015;Zhang et al, 2013). Given the complex thermal background, green spaces could produce a different latent heat of evapotranspiration and thus result in diverse cooling effects during summer (Spronken-smith et al, 2000;Sun and Chen, 2012).…”

A B S T R A C TUnderstanding how green spaces affect urban temperature is crucial for assessing thermal benefits of landscape planning. This study investigated green space dynamics and land surface temperature (LST) in the Beijing metropolis. Landscape types were classified from QuickBird (2002) ). (2) LST change was not significant in the unchanged (0-0.19°C) and exchanged green space (in the range of −0.02-0.25°C). However, there were minor decreases of LST in areas of green expansion (in the range of −1.11°C to −0.67°C) and major increases in LST in the areas of green losses (1.64-2.21°C). The results indicated that the number of green spaces is not the only criteria that should be assessed for temperature mitigation. Ecosystem services of temperature mitigation are not equal between the loss and expansion of green spaces even within same area. Greater focus on protecting natural forests in cities might provide greater benefits for climate mitigation.

“…4) [21]. A study by Sun and Chen (2012) indicated that the mean temperature of water bodies was 29.49°C, which is lower than the green land (30.07°C) and built-up area (32.86°C). Urban water bodies can beautify the surroundings, maintain ecological systems, and improve human interactions in the urban city.…”

“…Numerous researchers, such as [21], [25], [26], define the bioclimatic approach as the radical and comprehensive employment of natural vegetation, greenery, water bodies, and landscape design that are suited to climatic variability in urban areas. Vegetation and water bodies are commendable tools to reduce thermal discomfort because they are ecologically friendly, offer a high cooling effect, and encourage a pleasant and healthy living environment through climate adaptation [27]. Urban heat effects can be reduced and alleviated if a higher amount of green spaces are assimilated into developing an urban landscape [1].…”

Abstract-This paper aims to investigate the effects of using natural resources that incorporates the basis of a sustainable city design in efforts to improve the urban thermal comfort in a hot and humid climate. Currently, one of the most crucial world environmental issues is urbanization in a hot and humid climate. In tropical areas, if the urban landscape is poorly designed, it will cause outdoor thermal discomfort. Natural plants and water bodies in the hot and humid landscape has a direct influence over the temperature of urban cities. Water bodies, for example, are able to lower the atmospheric temperature; whereas plants also can affect the surroundings passively. The effects of wet surfaces are increased if there is a presence of a shadow. Therefore, vegetation and water bodies are used in designing a sustainable city in order to increase the quality of outdoor thermal comfort in a hot and humid climate. This is hoped to provide a better and more comfortable human living environment.
