| 摘 要： | 对北京妙峰山地区３种不同林地类型（未成林造林地、已郁闭幼林地、成林地）的土壤ＣＯ_２释放量的动态研究表明，未成林林地的ＣＯ_２释放量明显高于有林地；林地ＣＯ_２释放量与土壤表层或亚表层的温度、湿度在一定范围内呈线性正相关，而与光照度无关；ＣＯ_２释放量昼夜变化也有一定规律。

| Abstract: | The study on the soil CO_2 evolution from three types of woodland in Beijingshows that:(1) the soil CO_2 evolution from afforested land has higher value than that of theforest land;(2)the soil CO_2 evolution has linear regression positive correlation with the soiltemperature and soil moisture content at a certain range, and has no relations with the illu-minance;(3)it also has regular pattern for circadian change. |

| Keywords: | soil CO_2 evolution rate greenhouse gas woodland |
