英文摘要：

Casuarina equisetifolia is a major species planted in protection forest along the coast of southeast China.At present,how to sustain and enhance its environmental regulation functions has become important science question for local protection forest management.This paper reviewed the research at home and abroad on nutrient cycling,energy flow and protective functions of C.equisetifolia ecosystem in coastal zone as well as on the effects of forest management measures on forest ecosystem,indicating that C.equisetifolia plantations have the characteristics of high production,high photosynthesis rate and better adaptive abilities.The relationship between disturbance and the degraded C.equisetifolia ecosystem was discussed.Then the suggestions were made for the restoration and reconstruction of the damaged C.equisetifolia protection forest and the management of its ecosystem.
