摘要/Abstract

摘要： 采用6种方法计算了辽西地区的人工林气候生产力.结果表明,辽西平均人工林生产潜力为8.8t·hm^-2·年^-1,其分布趋势从东南向西北逐渐降低,与降雨量分布一致.针对地区特点,生态地区法、层次递推法和综合模型是适宜的气候生产力计算模型.对比分析表明,辽西现实人工林生产力水平处于极低水平,提高人工林质量,挖掘生产潜力是今后人工林发展的关键.

关键词: 辽西, 人工林, 气候生产力

Abstract: Calculations by six models of climatic productivity showed that the average climatic productivity of plantations in western Liaoning area was 8.8 t穐m^-2 穣r^-1,and had a decreasing trend from southeast to northwest,which was coincided with the distribution of rainfall.Three models were suitable to be used to calculate the climatic productivity of plantations in the area.The present plantation productivity was really lower than the potential climatic productivity,and the great potential was available in improving plantation productivity through the improvement of forest quality.

Key words: Western Liaoning area, Plantation, Climatic productivity
