Biogeochemistry Of Subtropical Evergreen Broad-Leaved Forest And Typhoon Disturbance

About this book

Language: English

This important contribution is the result of the author’s theoretical thinking and long-term high-value data collection by examining the response of subtropical forest ecosystems to typhoon disturbance in great detail. The author has bridged the gap between disturbance ecology and biogeochemistry with an interdisciplinary and quantitative approach. Biogeochemistry of Subtropical Evergreen Broad-leaved Forest and Typhoon Disturbance brings together much of the current understanding of the biogeochemical cycling processes in the subtropical forest and the mechanisms of forest productivity maintenance under frequent typhoon disturbances.

Biogeochemistry of Subtropical Evergreen Broad-leaved Forest and Typhoon Disturbance is certain to be of interest to anyone fascinated by the relationship between productivity and ecosystem structure and function. Those interested in climate change, sustainable management of forest ecosystems. and the interactions between forest ecosystem and natural disturbances will want to have this important book.
