Abstract: |
|
Based on Landsat 8 image data, this paper estimates the biomass of three coniferous forest in
Dongguan, including Pinus forest, Cunninghamia lanceolata and coniferous mixed forest . By using correlation
analysis, principal component analysis and stepwise regression, a remote sensing estimation model of coniferous
forest biomass was established, and its determining coefficient (R2) value were 0.880 9, 0.832 5 and 0.964 0
respectively, which reached a significant level. The applicability test showed that the model reached 0.05
significant levels and could be used for estimating the biomass of coniferous forest in Dongguan.
