將樂縣國有林場位于中國福建省。將樂縣總面積為2246.7 km2（東經(jīng)117° 05’～117。40’,北緯26°26’～27°04’）。該地區(qū)為濕潤的熱帶季風(fēng)氣候,并具有海洋和大陸性氣候特征。平均相對濕度為81%,無霜期為287天。土壤濕潤肥沃,類型為紅壤土。全縣年平均降水量為1699 mm,年平均氣溫為18.7°C。全縣林地面積為1887 km2,占全縣總面積的83.9%。林場的主要造林樹種是杉木、毛竹和馬尾松。其中,杉木是最主要的優(yōu)勢樹種。（1）監(jiān)測與繪制森林碳儲量圖對于評估減緩氣候變化措施的效果至關(guān)重要。有證據(jù)表明林緣碳儲量小于森林內(nèi)部。本研究使用中國東南部地區(qū)杉木人工林生態(tài)系統(tǒng)的野外調(diào)查數(shù)據(jù),對不同海拔高度處的杉木人工林林緣和森林內(nèi)部的碳儲量進(jìn)行了測定和分析。研究結(jié)果表明,森林碳儲量隨海拔高度的增加呈現(xiàn)顯著增加的趨勢。研究結(jié)果也表明,林緣碳儲量顯著低于森林內(nèi)部。杉木人工林碳密度值介于265 Mg C ha-1（林緣）和320 Mg C ha-1（森林內(nèi)部）之間。本研究結(jié)果表明,忽略林緣效應(yīng)的估計將高估碳密度達(dá)9.46%。綜上所述,在國家碳儲量調(diào)查的過程中應(yīng)該充分地考慮林緣效應(yīng)...
