Agroforestry is rapidly being transformed from an empirical， largely anecdotalcollection of beliefs and practices into an emerging science in the field of natural resourcemanagement. The book is a major contribution towards this goal.This book reported findingsfrom seven different pot and field trials and field Ginkgo agroforestry systems mainlyincluding interactive effect of light， moisture and nutrient on Ginkgo， intra-specificcompetition of ginkgo， inter-specific competition between Gingko and crops. It providesthe most authoritative analysis available up to now of the various hypotheses that Ginkgoand crops， if properly chosen and managed， have a potential to increase productivecapacity of the systems. The main value of this book is that it brings together a substantialamount of original contribution to human knowledge from fundamental research， appliedresearch in pot trials and observations of real Ginkgo agroforestry systems in the field.
作者簡介
Following an un-dergraduate degree in Forestry Sciences and an MSc in Silviculturefrom Nanjing Forestry University （NJFU）， Nanjing， P. R. China，F(xiàn)uliang Cao （English name Sam） receive dhis PhD in Forest Ecol-ogy at the University of British Columbia， Canada， focusing on Ecological Basis for GinkgoAgroforestry. Since 1982 he has been working as one of the faculty member at NJFU， where he presented courses on silviculture， no-wood products， bamboo forests， methodology for no-wood products research.For the past twenty years， Dr. Cao has under- taken many key research projects mainly related to the ecophysiology， forest ecology and silviculture of poplar， bamboo and ginkgo. He has published several books titled as Chinese Ginkgo， Ginkgo， Growth Dy- namics of Southern Poplar Clones， Silviculture and Forest Ecology. Since 1992， his research interests have been focused on ginkgo tree species covering many aspects from genetics to physiology， forest ecology，silviculture and utilizations of ginkgo. The forty-three graduate students he has supervised over the past ten years have studied all aspects of Silviculture and some areas of Forest Ecology covering ecophysiology， pro-duction ecology， agroforestry， tree species selection，density control and modelling.Dr Cao is currently professor of Silviculture and vice-President at NJFU and vice-Chairman of ChineseGinkgo Research Institute.
