Productivity of Tropical Rain Forests

摘要: Tropical rain forests exist in a broad band across the Earth's warm, moist equatorial regions. They are characterized by their great stature, wide range of life forms (including many trees with buttresses, thick stemmed climbers, and herbaceous epiphytes), large number tree species. Despite importance tropical as store carbon, role carbon cycle is not well understood because they extensive, variable, generally more difficult to study than other vegetation types. This chapter discusses progress understanding controls on net primary productivity related quantity, ecosystem productivity, which requires close collaboration between disciplines. Studies at leaf stand scale, using eco physiological eddy covariance techniques, advancing one's temporal changes. Thereafter, scaling up whole regions biomes still remotely sensed data distribution land-surface cover, use interpolated climatological from ground or global circulation models drive models. There need develop new approaches this problem, perhaps large-scale experimentation observation. One aspect environmental change that has received attention influence forest edges created during logging burning.
