| 摘 要： | 根据大气环流模型预测,到21世纪中叶,大气中CO2浓度将增加1倍,气温升高约2℃。全球气候变暖对我国东北植被的响应如下：①未来东北森林建群种的变动类型可划分为3个类群,即扩展种群、退却种群和绝灭种群。②气候变暖后,根据模型预测,植物种群将向北迁移400～700 km,向上迁移250～350 m。根据上述结论提出了适应全球气候变化的保护对策。 |

| Abstract: | Based on the prediction by GCMS,till the middle of the 21st century,the concentration of CO2 in atmosphere will be doubled and the global temperature will increase about 2 ℃.The vegetation response in Northeast China to global warming will be as follows: The future alternate types of constructive species of Northeast forest can be divided into three types,including extending population,retreat population and extinct population.After climate warming,based on the model prediction,plant populations will move northwards about 400-700 km in the ground and move upwards 250-350 m along altitude.According to the above conclusions,a protective strategy for adapting to climate changes was put forward. |
