摘要
根据样地资料，分析和研究了天山云杉林生物生产力的地理分布格局。研究结果表明：天山云杉林生物生产力的地理分布规律十分明显，主要表现在：整个天山北坡，沿着天山的东西走向从山体的西段到中段再到东段，天山云杉林的生物生产力逐渐下降，即呈现出西高东低的趋势。其中，天山西部林区天山云杉林的生物生产力为9．336t·hm-2·a-1，中东部林区的生物生产力为6．576t·hm-2·a-1，两区相差2．760t·hm－2·a-1。本研究结论对于进一步探索天山云杉林生物生产力的地理分布规律与环境因子间的相互关系具有重要的意义。
Analysis of plot-based data showed clear patterns in the distribution of productivity in the Picea schrenkiana var. titinschanika forest of Xinjiang. Productivity decreased from the middle and east Tianshan to the west Tianshan.In the west Tianshan, productivity was 9. 336 t·hm-2 ·a-1 and in the middle and east Tianshan it was 6. 576 t·hm-2·a-1, the difference between two regions was 2. 760 t·hm-2·a-1. The paper concludes that further investigation of the relationship between the patterns of productivity and environment in Picea schrenkiana var. titinschanica forest is strongly warranted.
