This book provided the author's latest research results.Author paid attention to the functions and their differences in seven mycorrhizal types in this book.The contents mainly included the regulating functions of mycorrhizas in CO₂ efflux from soil and ecosystem,in net preprimary productivity and its response to the changes of temperature and precipitation in forest ecosystem,in foliar stoichiometry,in plant diversity along an altitudinal environmental gradient,and in host plant adaptability in variable soil water content during climate changes.

This book is suitable for researchers,graduate students,and senior undergraduates majoring in ecology,environmentology,mycology,microbiology and pedology as a reference book.
