Energy of forest systems in the Three Gorge Reservoir area.

Abstract--The energies of three forest ecosystems in the Three Gorge Reservoir area were analyzed. The results showed that the existing energies were 151. 2438, 139. 2014 and 175.1659 (x 10[sup 10] J/hm[sup 2]), the annual net fixed energies were 38.8924, 31.2214 and 46.8231 (x 10[sup 10]J/hm[sup 2]), and the utilization efficiency of light energies were 1.16, 0.99 and 1.40 for the Quercus acutissima forest(Q. A.), the Pinus massoniana forest (P. M.), and the Queresus acutissima and Pinus massoniana mixed forest (Q. P.), respectively. In the Three Gorge Reservoir Area, the energy efficiency of Quercus acutissima and Pinus massoniana mixed forest is the best. [ABSTRACT FROM AUTHOR]
