摘　　要：前期研究表明,不同下垫面及其组合对微气候调节作用有明显差异,硬地和草地由于缺少植被遮荫温度上升剧烈超过气象站参考数据成为局部热岛,而乔草、乔灌草垫面降温增湿效果显著,可形成亚热带城市中心冷岛。本研究以广州市中央公园为实例,引入线性规划方法,将亚热带城市公园的乔灌草下垫面面积最大化作为目标函数,依据相关规范及条例获得约束条件方程组,应用LINGO软件编程求解线性规划最优方案。该研究创新引入线性规划方法研究城市规划问题,为亚热带公园绿植高效化、建设森林城市提供科学决策依据。Previous research has shown that different underlying surface and their combination has obvious differences in the microclimate regulation.Hard lands and grasslands become local heat islands because of a lack of vegetation shade and temperatures rising sharply above weather station reference data,but the effect of cooling and humidifying of arbor-grass and arbor-shrub-grass compound land is remarkable,which can form a cold island in the center of subtropical city.Based on the example of Guangzhou central park,a linear programming method is introduced to maximize the area of the underlay surface of arbor-shrub-grass compound land in the subtropical city park as the objective function,the conditional equations are obtained according to the relevant norms and regulations,and the optimal scheme of linear programming is solved by LINGO software programming.This research introduces the linear programming method to study the urban planning problem,which provides the scientific decision basis for the high efficiency of green planting in subtropical parks and the construction of forest cities.
