[0031] A method for estimating forest biomass through strip LiDAR data upscaling, comprising the following steps:
[0032] 1) Overview of the test area
[0033] The research area is located in the state-run Yushan Forest Farm in Changshu City, Jiangsu Province (120°42′9.4″E, 31°40′4.1″N), which has a subtropical monsoon climate with a mild climate, an average annual precipitation of 1054 mm, and an area of about 1103hm 2 , and its altitude is 20-261m. Yushan Forest Farm belongs to the northern subtropical secondary mixed forest. The main forest types are coniferous forest, broad-leaved forest and mixed forest. The main coniferous tree species are Pinus massoniana, Cunninghamia lanceolata and Pinuselliottii, etc. The main broad-leaved tree species are Quercus acutissima, Liquidambarformosana and some evergreen broad-leaved tree species, such as Fagaceae, Lauraceae and Theaceae. The test area and sample plot distribution are as follows: figure 1 .
