摘要: 中国东北植被对全球变暖的响应如下:未来建群种的变动类型分为三个类群;气候变暖后,植物种群将向北迁移400~700km,向上迁移250~350m;栽培作物的界线有所变化;大部分植物物候发育将提前一个节律;主要森林生态系统生产力将提高7.65%,农业生态系统产量将提高36.4%.

Abstract: Based on the prediction of GCMS, by the middle of the next century, the concentration of CO2 in atmosphere will be doubled and the global temperature will increases about 2℃, vegetation response to global warming,in Northeast China will be the followings:1. The future alternate types of edificators can be divided three types (extending population; retreat population; extinct population). 2. The decision of the future distribution border of edificators as climate warming. Based on this formula: WI =288. 94-251X-0.81Y-0. 038H, (R=0.9812), it is calculated that the edificators will move northwards about 400-700 km when the temperature increases 2℃ and the population moves upwards 250-350m. 3. The influence of climate warming on the distribution border of cultivated crops. The northern survival border may move northwards 110-160 km for apple, 220 km for cotton. The elevation for ginseng cultivation will increase to 750-800 m. 4. The influence of climate warming on the growth and development of plant. Based on the function of frost-free period (F) = 3.7945 + 7.4581t, the growth period of plants will pro-long for 15 days and the phenological development of trees will roughly advance one sea-son. 5. The influence of climate warming on productivity. The productivity of main forest ecosystems will increase 7.65% and that of main agroecosystems will increase 36.4%.
