区域尺度陆地生态系统生物生产力研究方法

本文对国内外生物生产力区域尺度研究的理论、方法以及取得的成就和存在的问题进行全面而系统地评述。生产力机理模型是当前生产力生态学研究中的热点，而区域尺度转换是全球变化模型研究的关键问题。大量研究表明，植被叶面积指数是进行空间尺度拓展的连接点，而且叶面积指数的地带性分布规律是进一步拓展生态系统定位站研究结果的重要理论依据之一。

APPROACHES TO THE REGIONAL SCALE BIO-PRODUCTIVITY OF TERRESTRIAL ECOSYSTEMS

This paper gives a comprehensive and systematic review of the theories and models as well as achievements and problems on the regional scale of bio productivity in terrestrial ecosystems at home and abroad. Present researches on productivity ecology are focused on the modeling of productivity mechanism, and the regional scaling is the key of the global change modeling. Substantial studies showed that leaf area index of vegetation is the link of spatial scaling, and the distribution patterns of leaf area index are one of the most important theories for the sacling of located ecosystem researches.
