摘　　要：居住区作为城镇居民三生活动最主要的空间单元,其热环境质量直接决定了小区内居民的舒适感和幸福度.本文在归纳总结城镇居住区绿地组合模式的基础上,基于非静力流体力学技术和热力学原理,耦合有限差分及交替方向隐式算法对小区范围内不同模式结构组合的绿地生态系统进行热效应模拟研究,通过对比分析不同模式组合的绿地系统热环境效应特征,探寻多模式组合下的居住区绿地与局地热环境间的交互关系.结果表明:在相同的模拟条件下,“中心+宅间”绿地组合模式的热环境效应最好,“组团+宅间”模式次之,“宅间”模式热环境效应最差;模拟区域内三种绿地组合模式的最高最低温度差分别为2.36、2.31和2.34℃,且温度自西南向东北方呈现圈层式分布特征;多绿植类型的组合模式对局地热环境的改善效果依次为:草+灌+乔>草+乔>草+灌>草,灌木对绿地热环境舒适度的改善效果不显著.该研究能够为居住区绿地规划设计与实践提供科学参考.As the most important spatial unit of urban resident activities,the thermal environment quality of residential area determines the thermal comfort and happiness of residents.On the basis of summarizing the green space combination models in urban residential areas,this paper adopts non static fluid dynamics technology and thermodynamic principles,coupled with finite difference and alternating direction implicit algorithms,to conduct thermal effect simulation research on green space ecosystems with different pattern structure combinations within the community scope.By comparing and analyzing the thermal environment effect characteristics of green space system with different combination modes,the interaction between green space and local thermal environment in residential areas under multi-mode combination is explored.The results show that under the same simulation conditions,the“center+residence”green space mode has the best thermal environment effect,the“cluster+residence”mode takes the second place,and the“residence”mode has the worst thermal environment effect.The maximum and minimum temperature differences of three green space combination modes in the simulation area are 2.36,2.31 and 2.34℃,respectively,and the temperature presents a circular distribution from southwest to northeast.The improvement effect of the combination mode of different green plant types on the local geothermal environment is as follow,grass+shrub+tree>grass+tree>grass+shrub>grass.This improvement effect of shrubs on the thermal environment comfort of green space is not significant.The study can provide scientific reference for the planning,design and practice of green space in residential areas.
