通过野外实地调查对福建省柑橘林生态系统碳储量及其分布特点进行研究.结果表明:柑橘各器官生物量回归模型显示,柑橘各器官的相关性较好,树干、树叶、果实的相关系数均大于0.90,树高和基径的相关系数为0.89;柑橘林生态系统有机碳密度为222.80 t·hm~(-2),其中,土壤(0-100 cm)碳密度为200.21 t·hm~(-2),占总有机碳密度的89.86%,果树碳密度为22.58 t·hm~(-2),占10.14%;1978-2007年,柑橘林生态系统碳储量从3.16×10~6 t增加到37.97×10~6 t,年均增加1.20×106 t,表现为碳汇;在第4-6次(1993-2003年)森林资源连续清查期间,柑橘林生态系统碳储量占全省森林生态系统碳储量的比重都高于2.43%;柑橘林生态系统碳储量在空间分布上表现出由闽东南向闽西北递增的规律,9个设区市的柑橘林生态系统碳储量呈现出不同的消长规律,三明市、南平市、漳州市3个地区平均柑橘林生态系统碳储量占全省的63.43%.
通過野外實地調查對福建省柑橘林生態繫統碳儲量及其分佈特點進行研究.結果錶明:柑橘各器官生物量迴歸模型顯示,柑橘各器官的相關性較好,樹榦、樹葉、果實的相關繫數均大于0.90,樹高和基徑的相關繫數為0.89;柑橘林生態繫統有機碳密度為222.80 t·hm~(-2),其中,土壤(0-100 cm)碳密度為200.21 t·hm~(-2),佔總有機碳密度的89.86%,果樹碳密度為22.58 t·hm~(-2),佔10.14%;1978-2007年,柑橘林生態繫統碳儲量從3.16×10~6 t增加到37.97×10~6 t,年均增加1.20×106 t,錶現為碳彙;在第4-6次(1993-2003年)森林資源連續清查期間,柑橘林生態繫統碳儲量佔全省森林生態繫統碳儲量的比重都高于2.43%;柑橘林生態繫統碳儲量在空間分佈上錶現齣由閩東南嚮閩西北遞增的規律,9箇設區市的柑橘林生態繫統碳儲量呈現齣不同的消長規律,三明市、南平市、漳州市3箇地區平均柑橘林生態繫統碳儲量佔全省的63.43%.

Organic carbon in citrus forest was detected with the field investigation and measurement in Fujian Province. The results showed that citrus organs had a positive correlation each other based on the analysis of biomass linear regression model. Correlation coefficient of stem, leaf and fruit both exceeded 0.90. The correlation coefficient between height and base diameter was 0.89. The carbon density in the ecosystem was 222.80 t·hm~(-2), in which soil (0-100 cm) carbon density was 200.21 t·hm~(-2), vegetation carbon density was of 22.58 t·hm~(-2), accounting for 89.86% and 10. 14% of total carbon density, respectively. From 1978 to 2007, the organic carbon storage in citrus forest ecosystem increased from 3.16×10~6 t to 37.97×10~6 t in Fujian Province, which played a role of sink. During the continuous forest inventory from 1993 to 2003, the proportion of carbon storage between citrus and forest ecosystem was more than 2.43% in Fujian. The carbon storage in citrus forest ecosystem increased from southeast to northwest in Fujian. The organic carbon storage in the 9 prefectures in Fujian showed different growth and decline law. The organic carbon storage in Sanming, Nanping and Zhangzhou accounted for 63.43% of the whole province.
