摘　　要：为解决因热力管道散热带来的绿地草坪死亡问题,采取对长安街沿线绿地内地下热力管道铺设聚苯乙烯隔热板。试验结果表明,隔热板铺设后,不同深度土壤温度均降温明显,草坪返青期延后20 d,5月份周生长量减少2 cm,8月份发病率由原来的95%降低到现在的50%,并从病后无恢复能力提高到35%的恢复能力,因此隔热板的铺设对缓解草坪死亡效果显著。To resolve the problem of death of green lawn due to thermal energy pipeline radiation,polystyrene insulation panels were laid over the heat pipe under green space in Chang＇an Street. The results show that soil temperature decreased obviously at different depths, turning green time postponed for 20 days, lawn-week growth reduced 2cm in May, disease incidence reduced from 95% to 50% and restoring force incresed from 0% to 35% in August. The laying of insulation panels had a significant effect on reducing lawn death.
