摘　　要：依据森林资源二调数据,对毛瑞林场内的天然林进行随机抽样布点,采用换算因子连续函数法估算其碳汇量,并采用造林成本法计算其碳汇价值;利用Arcgis中的空间分析功能对研究区内的碳汇价值进行了插值分析和重分类。结果表明:(1)毛瑞林场天然林碳汇总价值约为5.6千万元;(2)利用地统计分析中的克里格插值法对天然林碳汇价值进行评价,结果较为客观真实,与实际情况相符。Based on the forest resources inventory data, Setting points and random-sampling in the natural forest in Maorui Forest Farm were randomly conducted. The carbon sinks of the natural forest were estimated by using conversion factor and continuous function method, the values of carbon sinks were calculated by using afforestation cost method and the values of carbon sinks were analyzed with interpolation method and were reclassified. The results demonstrate that （l） the total carbon-sink values of the natural forest was about 5.6 ten million Yuan; （2） the evaluation results of carbon-sink values of the natural forest by Kriging interpolation method were objective and truth, consistent with the actual situation.
