摘　　要：由于建筑及植物配置形成的区域小气候会导致同种植物长势的差异性,为研究不同小气候环境中月季光合能力的差异性,现以月季(Rosa chinensis)为研究对象,以阳光下样地为对照,分析建筑楼前、建筑楼后和树荫下3个样地与光下样地内的土壤环境、大气环境的差异性,研究了不同小气候环境中月季光合生理指标差异性。结果表明:对比阳光下样地,树荫下与建筑楼后样地的光照强度、环境温度均降低,空气湿度均增大,月季的净光合速率、蒸腾速率均下降,气孔数目均减少,楼前所测结果均相反;楼后、楼前样地的二氧化碳浓度均下降,月季气孔导度及净光合速率均降低,楼前样地所测数值均相反。通过研究月季光合生理指标对不同小气候环境的差异响应为其栽培地点的选择提供了参考。Since the architecture and facilities configuration and other environmental factors can lead to plant photosynthesis change under microclimate,the Rose chinensis was selected as the object in this study,the front of building,the back of building,the shade and the sun four locations of microclimate were investigated in Qingdao Agricultural University,the soil environment,atmospheric environment effects on Chinese rose photosynthetic physiological indexes were analyzed,in order to study the response of the physiological index of rose in different microclimate.The results showed that with the plots under sun as the control,the shade and the back of building plots light intensity,ambient temperatures were lower,the air humidity increased,rose net photosynthetic rate and transpiration rate decreased,the number of stomata reduced,the front of building results were measured before contrast;the front and back of building plot concentration of carbon dioxide decreased,between Rosesintercellular CO2 concentration were lower,the measured values of the front of building plot were contrary,which provided the reference for the selection of rose cultivation sites.
