摘 要：
为探究芜湖市城市森林土壤理化性质及碳储量特征,选取神山公园、安徽师范大学、安徽工程大学、长江沿岸防护林作为样地,代表落叶阔叶林(柳树、白杨)、常绿针叶林(松、柳杉)、常绿阔叶林(香樟、桂花)和灌木这4种群落类型,进行林地土壤分层(0~20 cm、20~40 cm、40~100 cm)采样,分析相关指标。结果表明:芜湖市城市森林土壤容重平均为1.40 g cm~(-3);p H值变化范围在6.73~8.21之间,属于中性土及碱性土;土壤全磷平均含量为0.50 g kg~(-1);有机碳含量为2.12~11.04 g kg~(-1)。随着土壤深度的增加,土壤pH、全磷和土壤有机碳均呈下降趋势,土壤容重则表现出相反的趋势。总体而言,芜湖市城市森林土壤全磷、有机碳含量与碳储量均较低,为增加土壤碳储量,建议在城市森林建设过程中增加落叶阔叶林的种植面积。利用芜湖市各类型森林绿地土壤含水量、pH、全磷的含量及容重,使用偏最小二乘回归分析法,预测当地有机碳与无机碳的含量,效果较好,推广到一般性森林土壤碳含量预测,还需要进一步实验验证。

摘 要：
To investigate soil physic-chemical characteristics and soil carbon storage in urban forest of Wuhu, the sample sites were selected in the Shenshan Park, Anhui Normal University, Anhui Polytechnic University and the protection forest along the Changjiang River, which were on behalf of the deciduous broad-leaved forest(Salix babylonica L. and Populustomentosa Carr.), evergreen coniferous forests(Pinus. And CryptomeriafortuneiHooibrenk ex Otto et Dietr.), evergreen broad-leaved forest(Cinnamomumcamphora(L.) Presl. and Osmanthussp.) and shrub as the main community types, respectively. Some relevant indicators such as soil pH, bulk density, total phosphorus(TP),organic carbon and inorganic carbon were analyzed. The results showed that the average of soil bulk density was 1.40 g cm~(-3). The p H value varied from 6.73 to 8.21(belonged to neutral and alkaline soil). The average content of soil TP was about 0.50 g kg~(-1) and the contents of organic carbon ranged from 2.12 to 11.04 g kg~(-1). With the increase of soil depth, soil moisture content, pH, TP and organic carbon showed the decreasing trend. However, soil bulk density increased with increasing soil depth. In general, the content of TP, organic carbon and carbon storage was at a relatively low level in urban forest of Wuhu. In order to increase the soil carbon storage of urban forest, we suggested to increase the planting area of deciduous broad-leaved forest during urban forest construction. According to the contents of soil moisture, TP, and pH, soil bulk density of urban forest, the partial least squares regression was established to predict the content of organic carbon and inorganic carbon in local soil. But it should be verified by further experiments when it was extended to predict soil carbon content of general forest.
