Abstract

The purpose of this study is to assess actual and potential environmental aspects related to the impact of local tree areas on local climate control and to assess external thermal comfort. This has allowed us to assess its sustainability in the light of achievable environmental benefits. Sustainability can be defined as the property of a material or product that indicates how well it meets current requirements for a particular application. These demands affect the well-being and health of city dwellers. We approach this study with an ecological approach, focusing on the effects of native trees (palms and olive trees) and exotic trees (Ficus letesa). Adjust the microclimate of the city. The study highlights the positive effects of plants on urban outdoor spaces in the city of Biskra during July and August, the hottest months of the year when temperatures can reach values above 50 degrees Celsius. I made it A green strategy is an essential element in improving the external local climate, especially in dry climates. The main criteria we relied on in this study included vegetation density, tree placement and orientation, and country albedo. Based on these three criteria, we have achieved very important results in terms of improving and adjusting the urban microclimate. - Selection of the components of the regional urban forest model that have the greatest impact on regional climate and cooling effects. In addition to these factors, the impact of urban forests on local climate also emphasizes permeability, tree abundance, sky visibility, leaf area index, and distance between trees. -Urban green spaces, especially olive and palm trees, have a positive impact on the outdoor microclimate, reduce the urban heat island effect in the summer in the shade of tall trees and shrubs, attenuate solar radiation, Being able to block the flow of heat from the sky, thereby increasing the comfort of the microclimate and change. In addition, evaporation and transpiration from plants reduce temperature and increase humidity.
