摘要

西班牙城市通过增加城市供暖来改变微气候参数;因此,有几种策略可以帮助减少干旱环境中的这种影响。然而,在这种情况下,有必要考虑到这两种策略的有效性。为此,设计了96个场景,结合了2个建筑高度(3和6米),3个街道宽度(16、20和30米)和4个方向(E-O、N-S、NO-SE和NE-SO)。利用ENVI-met软件模拟了提出的情景的热行为,并通过现场微气候监测验证了模型的有效性。模拟阶段为:1。morfologia、2。forestacion、3。反照率和4.组合策略。最重要的发现表明,合并联合策略是最有效的选择,因为它增强了个人利益;在最高温度下下降12%,在最低温度下下降10%,在平均温度下下降11%。英国城市修改微气候参数,增加城市变暖。在这方面,有一些战略有助于在干旱环境中减少这种影响。本工作评估可切实纳入的战略的效力水平。为此,设计了96个场景,结合2个建筑高度(3和6米),3个街道宽度(16、20和30米)和4个方向(E-O、N-S、NO-SE和NE-SO)。通过使用envimet软件,对所提议情景的热行为进行了模拟;该模型通过原位微气候监测得到验证。= =地理= =根据美国人口普查,该镇的土地面积为。morphology、2。forestation、3。= =地理= =根据美国人口普查,该县的总面积为,其中土地和(3.064平方公里)水。最重要的调查结果表明,采用综合战略是使个人利益最大化的最有效选择;= =地理= =根据美国人口普查局的数据,该县总面积为,其中土地和(1.0%)水。
