METHOD FOR EXTRACTING BOUNDARY LINE OF ON-YEAR AND OFF-YEAR MOSO BAMBOO FORESTS BASED ON SENTINEL-2 REMOTE SENSING DATA

원문 (중국어)

Disclosed is a method for extracting a boundary line of on-year and off-year moso bamboo forests based on Sentinel-2 remote sensing data, and relates to the technical field of forestry remote sensing. The method includes classifying remote sensing images to acquire spatial distribution of three land type results, the three land type results including several on-year moso bamboo forests, several off-year moso bamboo forests and other vegetations between the on-year and off-year moso bamboo forests; extracting an initial boundary line of the on-year and off-year moso bamboo forests according to spatial distribution of three land type results; building a buffer region of the initial boundary line, and acquiring intersecting pixels of the buffer region and the spatial distribution of three land type results; and calculating pixel thresholds by using the intersecting pixels, and acquiring a final boundary line of the on-year and off-year moso bamboo forests. Using the above method can accurately obtain the boundary line between on-year and off-year of moso bamboo forests.
