摘　　要：选择柳树林、栾树林、丁香林、琼花林样地,对林内、林缘等样点进行林分空间CO2浓度、相对湿度、光合强度等环境效应指标测定。结果表明:林内样点测试指标间差异显著,林缘样点测试指标间的大气CO2浓度差异不显著,相对湿度及光合强度差异极显著。The forest of Salix babylonica , Koelreuteria paniculata , Syringe reflexa , and Viburnum macrocephalum were the pot of the experiment. The CO2 density, relative humidity and light intensity were the indexes of our survey. There was a good relation between the sample place and the environmental benefits; significant differences were found in the different sample pot. Of the indexes around the forest, there were no significant differences in the CO2 density index but great differences in relative humidity and light intensity.
