摘　　要：生态价值的估算是当今生态学研究的热点方向。大学城进驻小谷围岛后,小谷围岛的生态环境遭受严重的破坏。我们实地调查大学城小谷围岛的植被和土壤的情况,并应用ARCgis和统计方法对调查数据进行处理,采用生态学相关理论与方法对处理数据进行分析与计算,得出小谷围岛制氧固碳量和土壤图土壤的有机质量。然后,通过假设小谷围岛在不建设大学城的的条件下自然发展,计算其制碳固养量和土壤有机质量。最后我们用前者减后者,并换算成经济价值。我们得出广大学城进驻小谷围岛5年后,小谷围岛的生态价值损失是12.11亿人民币。The estimate of ecological value is now one of the most prevalent ecology research.After the university city built in Xiaoguwei island,the Xiaoguwei island ＇s ecological environment was destroyed seriously.First of all,we invested the Xiaoguwei island and got the realistic datum of the vegetation and the soil about it.Secondly,we delta with those datum by using ARCgis and statistical method,and analysed those datum with the proper method and theory about ecology.Thirdly,we got the real quantity of the carbon—fixation and oxygen production and the organic fertilizer by counting those datum.Then,we assumed that the university city were built in Xiaoguwei island,and got the suppositional quantity of the carbon—fixation and oxygen production and the organic fertilizer by the same way.Finally,we got the conclusion,the university city built in Xiaoguwei island five years later,the total loss of the ecological value was 1 211 billions clollar.
