摘　　要：研究了苏州城市绿地系统中的3种节约型植物树群类型的6个研究样本的温度变化影响因素及其热能效应评估方法。结果表明,2月、8月3种类型树群的外环境温度对其树群内环境温度影响的相关系数(r)和回归系数(t)都达到显著或极显著水平,二者存在显著或极显著正相关和直线回归关系;不同月树群内外环境的光照度对树群内环境温度影响的相关系数和回归系数明显不同,说明树群外环境温度、树群内外环境光照度对3种类型树群的内环境温度影响不同。研究样本树群8月和2月的降温热能效应折算净总电量为13 749.975 k W·h;树群平均单位面积降温热能效应折算净总电量为1.854 k W·h/m2。苏州市古城区面积约926 005.718 4 m2的城市绿地系统中的节约型树群,8月和2月降温热能效应折算净总电量为430 704.373 k W·h。The temperature variation factor of six samples were investigated, within the green space system in the city of Suzhou,collected from three types of tree communities of oriented conservation, and the assessment method of its thermal energy effect. The results showed that in either August or February,the external environment temperature and internal environment temperature of the three types of tree communities had the correlation coefficient（r） and regression coefficient（t） reaching the significance of 0.05 or 0.01,with significant or highly significant positive correlation and simple linear regression relationship. The light intensity in external and internal environment of tree communities and internal environment temperature have prominently different coefficients r and t in different months. These results suggest the effects of external environment temperature and light intensity in external and internal environment on the internal environment temperature of the three types of tree communities are different. The sample tree communities express a net temperature-lowering thermal energy of 13 749.975 k W·h（converted to electricity） in August and February,with the unit area express an average value of 1.854 k W·h / m2. The tree communities of oriented conservation within the green space system with an area of approximately 926 005.718 4 m2,located within the ancient city district,express a net temperature-lowering thermal energy of 43 0704.373 k W·h.
