Abstract

Abstract: Adopt the method of space instead of time,we seleted the vegetation which was covered with caryi ng soil and ecologicoc vegetation campe during 9 years as rsereh oljets in Beiin Shouyum Iron Ore Mine. Spatial paltem of cahon density of vegetatin wih dfen rstoraion age was sudied The resuls show that the carbon density of boh aboveground and root decrased firsly and then increase with the years flwoe and it began lo slabli afer the 5^th year. Liters cabhon densiy incresed floed restoraton ages .umil the 6^th year it reached sabiliaion conditin. Soil organic carbhon of rstorartion vegetation system inre gral .and soil catom densit of natural veti aroumd was as2.07-2.87 times as that of each level of restoration vegelation. There is great onganic carhon sequstration plentita in soil of iron ore mine.
