摘要
根据我国北方地区农业生态系统、沙地生态系统、草原生态系统以及长白山阔叶红松林生态系统中的优势植物种对高CO2浓度和土壤干旱的响应差异,预测了在CO2浓度增加和土壤干旱化趋势下不同优势植物的可能变化,并提出了应对这种变化可采取的措施。
Based on the differences of response of dominant plant species in agriculture ecosystem, sandland ecosystem, grassland ecosystem and pine broadleaf forest ecosystem in Changbai mountain in northern region of China to CO_2 enrichment and soil drought, the possible change of different dominant plant species under CO_2 enrichment and soil drought were forecasted, and the measures to reply this change was put forward.
