摘要:

人工植被是吸收CO2维护生态系统健康的重要生物成分,干旱区人工碳汇林在CO2减排方面具有重要的作用。应用2009年8月TM数据,提取克拉玛依人工减排林生态景观格局信息,并应用NDVI指数估算植被碳密度。通过测定乔木层及草本层生物量,估算出人工植被乔木层及草本层碳密度。结果表明,克拉玛依人工减排林乔木层的平均碳密度值为37.04 mg/hm2,1 m×1 m样方内草本层平均碳密度为59.65 g/m2,地上植被碳密度约为37.64 mg/hm2,植被层碳储量为250 915.5 mg;随着植被的生长发育及生物量累积效应的发挥,人工植被的碳汇功能还将进一步增大。

Abstract:

Artificial vegetation is the important bio-component with absorbing dioxide carbon for supporting ecosystem health.Artificicial carbon sink forest play important function on reduction of carbon dioxide emission.Based on TM data of August,2009,the eco\|landscape pattern information is  obstained.Furthermore,using NDVI to estimate vegetation carbon density,which is a viable method.Through investigation the biomass of arbor layer and herbage layer,the carbon density of arbor layer and herbage layer are determined.The result as follows,the average carbon density is 37.04 mg/hm2 in the arbor layer,meanwhile,the average carbon density is 59.65 g/m2 in the 1 m×1 m sample site in the herbage layer.So,the total vegetation carbon density above the ground is about 37.64 mg/hm2.As a result,the carbon reserves is 250 915.5 mg in the whole vegetation layer.With the vegetation growth and biomass accumulation effects,the carbon sink function of the artificial vegetation will be further more bringing into played.

Key words: NDVI    Artificial forest    Carbon storage    Carbon cycle    Arid area    Source and sink of carbon dioxide
