摘要:
 林木营养积累是地球生物化学循环中非常重要的部分,对维持生物与非生物环境间物质交换平衡有重要作用。基于实测,对烟台市森林生态系统积累营养物质功能进行评估,依托ArcGIS进行数据空间分析,以分析营养物质积累在树种间、县区间、地形间的数值和空间差异,结果表明,烟台市森林生态系统积累元素总实物量为11 190.5 t·a-1,积累N、P、K的物质量分别为6 787.29、776.04、3 627.16 t·a-1;积累元素的总价值量为16 794.83万元·a-1,积累N、P、K的价值量分别为14 253.36、543.23、1 998.24万元·a-1。单位面积积累元素实物量为21.48 kg·hm-2·a-1,单位面积价值量为322.2元·hm-2·a-1。单位面积森林资源积累营养元素的能力在树种间、县区间、不同地形间存在着不同程度的差异。
Abstract:
 In this paper,the function of nutrient accumulation of forest ecosystem in Yantai city was studied,and the data spatial analysis was carried out based on ArcGIS.The results indicated that the total physical amount of accumulated elements in the forest ecosystem of Yantai was 11 190.5 t·a-1,of which the amounts of N,P,and K were 6 787.29,776.04 t·a-1,and 3 627.16 t·a-1,respectively.The total value of accumulated elements was 167.948 3 million yuan/a,of which the values of N,P,and K were 142.533 6,5.432 3,and 19.982 4 million yuan·a-1,respectively.The physical amount of accumulated elements per unit area was 21.48 kg·hm-2·a-1,and the value per unit area was 322.2 yuan·hm-2·a-1.The ability of forest resources to accumulate nutrient elements per unit area differed among different tree species,counties and terrains.
