| 摘 要： | 实验研究了毛乌素沙地优势植物种柠条、杨柴、油蒿的根长、主茎高、地径等生长量对大气中CO2浓度增加和土壤干旱的响应。结果表明:大气中CO2浓度增加和土壤干旱对植物生长量的影响是十分复杂的,不仅不同的植物种对CO2浓度的反应不同,而且不同的植物对土壤干旱的反应也有差异,由此而使得大气中CO2浓度增加和土壤干旱对植物的复合影响十分复杂。

| Abstract: | The response of root length, plant height and basal diameter growth of dominant plant species in Mu Us sandland to atmospheric CO_2 enrichment and soil drought is experimental studied. The results show that the impacts of atmospheric CO_2 enrichment and soil drought on plant growth are complicated. The response of different plant species to CO_2 is different, but the response of different plant species to soil drought is different too. Therefore, the compound impacts of atmospheric CO_2 enrichment and soil drought on plant are very complicated. |
