摘要:
借助G IS和数学模型集成技术,利用福建省气象观测资料推算出全省年均温度、降水量和实际蒸散量的125 m×125 m栅格数据,采用植被净第一性生产力改进模型结合林地土壤质量系数,修正计算区域林地生产力栅格数据,然后借助动态聚类分析模型进行区域林地生产力分区。结果表明福建省林地生产力介于262.2 g/(m2.a)~2 100.6 g/(m2.a),9个设区市林地生产力均值大小顺序为:漳州>龙岩>福州>厦门>三明>莆田>南平>泉州>宁德。全省林地以高、中生产力区占绝对优势,分别占全省林地总面积的76.26%和23.54%,其中高生产力区主要分布于闽北、闽西和闽中地区,而中生产力区则主要分布于闽北...
