山西太岳山森林土壤夏日CO_2释放速率的研究

A study on the rates of CO_2 release from forestland soils in northern China.

用LI- 6 2 0 0光合仪结合土壤呼吸箱测定了中国暖温带油松林、华北落叶松林、辽东栎林、辽东栎灌木林和稀草荒地夏日的CO2 释放速率 .结果表明 ,林地土壤的CO2 释放速率高于无林地 ,阔叶林地高于针叶林地 ,CO2

On Taiyue Mountain, in Shanxi Province, China, the rates of CO 2 release from forestland soils to the atmosphere in summer days were measured by using the Li cor-6200 instrument and a soil respiratory chamber. The CO 2 release rates were 10.05, 10.96,4.31, 4.94 and 4.67?m\+3·hm\+ -2 ·h -1 ,for a Quercus liaotungensis forest, a Quercus liaotungensis bush , a Chinese pine plantation, a Larix principis rupprechtii plantation and a bare land, respectively. And the CO 2 release rates were related with the organic carbon storage in the soils.
