| 1 | Responses of plant rhizosphere to atmospheric CO_2 enrichment显示文摘Plant root growth is generally stimulated under elevated CO2. This will bring more carbon to the below-ground through root death and exudate. This potential increase in below-ground carbon sink may lead to changes in long-term soil sequestration and relationship between host plants and symbions. On the other hand, changes in litter components due to the changes in plant chemical composition may also affect soil processes, such as litter decomposition, soil organic matter sequestration and hetero-nutritional bacteria activities. These issues are discussed. | LIN Weihong, ZHANG Fusuo & BAI Kezhi Institule of Bolany, Chinese Academy of Sciences, Beijing 100093, China: Department of Plant Nutrition, China AgriculturaI University, Beijing 100094, China | 2000 | Chinese Science Bulletin2000，45，2： | 2 |
