投影盖度

本文引入植物群落叶片投影盖度（FPC）的概念，其含义是植物群落叶片覆盖地表的百分率，它具有生态意义明确、适于描述植物群落水平结构的特点。

A useful concept , Foliage Projective Cover ( FPC ) that means the percentage of the land covered by foliage , was introduced , it had some ecological significances and was suitable for describing horizontal character of plant community .

因此，认为FPC是描述干旱区植物群落水平结构的有效方法，并可用于所有植物群落叶片投影盖度的度量。

Compared with the measured data , we thought that FPC was a useful and an effective method and theory to describe the horizontal structure of plant community in arid area , and it may be used for measuring FPC for all plant communities .

Foliage Projective Cover , Effective Tool for Describing Structure of Plant Communities

该模型用于模拟发生严重荒漠化的鄂尔多斯高原植物群落的季节及年生长、叶片投影盖度、蒸发系数。

The model was developed to simulate seasonal and annual growth , foliage projective cover ( FPC ), and evaporative coefficient in the Ordos plateau , where serious desertification happened recently .
