鄱阳湖生态经济区农田植被碳储量与碳密度分析

采用参数估算法对2001~2013年鄱阳湖生态经济区农田生态系统的植被碳储量与碳密度进行测算。结果显示：该区农田植被碳储量与碳密度均呈现上升趋势；农田碳储量与碳密度的变化受农作物种植结构、产量及总播种面积的影响。由此可见，植被碳储量的变化对生态系统的固碳能力具有重要的影响，农田植被碳储量与碳密度在一定程度上的提高，具有碳汇作用。研究农田生态系统碳储量、碳密度对控制温室效应具有重要的参考意义。

Analysis of Carbon Storage and Carbon Density of Crops in the Poyang Lake Ecological Economic Zone

This research adopts parametric evaluation method to calculate the carbon storage and carbon density of crops in Poyang lake ecological economic zone in 2001~2013. Results are as following:the carbon storage and carbon density of farmland vegetation in the area showed a trend of rising;the change of farmland carbon storage and carbon density are affected by crop planting construction,output and planting area.Thus,the change of the vegetation carbon storage has an important influence on e-cosystem carbon sequestration ability,farmlandvegetation carbon storage and carbon density increase with a carbon sink to a cer-tain extent.Discussing the farmland ecosystem carbon storage and carbon density has important reference meaning to control the greenhouse effect.
