多功能土地利用 应对未来景观福利和服务需要

该书是2005年在爱沙尼亚塔图市（Tartu）举行的未来景观网络国际研讨会的论文集，大会主题是“多功能土地利用：应对未来景观福利和服务需要”。传统的土地利用重视土地的生产能力，这种生产能力是同产品产量密切相关的，在对土地的改造中，为了方便运输和管理，大面积种植一种粮食，往往将不同景观特征同质化，     

The worldwide leaf economics spectrum

Bringing together leaf trait data spanning 2,548 species and 175 sites we describe, for the first time at global scale, a universal spectrum of leaf economics consisting of key chemical, structural and physiological properties. The spectrum runs from quick to slow return on investments of nutrients and dry mass in leaves, and operates largely independently of growth form, plant functional type or biome. Categories along the spectrum would, in general, describe leaf economic variation at the global scale better than plant functional types, because functional types overlap substantially in their leaf traits. Overall, modulation of leaf traits and trait relationships by climate is surprisingly modest, although some striking and significant patterns can be seen. Reliable quantification of the leaf economics spectrum and its interaction with climate will prove valuable for modelling nutrient fluxes and vegetation boundaries under changing land-use and climate.
