In order to effectively assess carbon balance in such ecosystems, rapid and accurate estimation of the aboveground biomass of a forest is critically needed. However, the current methods for biomass estimation and mapping are of limited spatial resolution and mostly depend on large numbers of measurements. In order to obtain better biomass estimation outcomes with higher spatial resolution, a rapid method is introduced for region-scale biomass estimation in alpine and canyon areas using space-borne light detection and ranging (LiDAR) data and optical remote-sensing images. Specifically, we explored alpine and canyon areas in Shangri-La City in China using space-borne LiDAR data from ICESAT-2 and optical remote-sensing images from Landsat8 OLI, Sentinel-2, and Microwave remote sensing Sentinel-1. An extrapolation model of the forest canopy heights in these areas was constructed with a 30-m resolution of continuous canopy height outputs. For continuously estimating the diameter at breast height (DBH) in Shangri-La City, a tree height-DBH growth model was constructed based on the LiDAR and remote-sensing measurements. Finally, based on the average DBH of the explored forests, a model was constructed for estimating and mapping the aboveground biomass and carbon storage in Shangri-La with a spatial resolution of 30 m. The results show that the forest canopy height in Shangri-La City is mainly in the range of 2.82\u201330.96 m, and that the estimation accuracy is verified by the LiDAR-based canopy height model (CHM) with a coefficient of determination of R2 = 0.7143. The inversion results were still largely affected by geospatial location factors (longitude, latitude), terrain factors (slope, elevation), and vegetation indices (NBR, NDGI, NDVI). Based on the relationship between the tree height and the DBH, the DBH of trees in Shangri-La City was estimated to be mainly in the range of 20 cm to 30 cm, and this estimate was verified by actual measurements with R2 greater than 0.7 all. Finally, the established model estimated the aboveground forest biomass and carbon storage of the study area of Shangri-La City in 2020 to be 1.28 \u00d7 108 t and 6.41 \u00d7 107 t, respectively. These estimates correspond to total accuracies of 92.28%, respectively.<\/jats:p>","DOI":"10.3390\/rs14225816","type":"journal-article","created":{"date-parts":[[2022,11,18]],"date-time":"2022-11-18T04:08:40Z","timestamp":1668744520000},"page":"5816","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":18,"title":["Mapping of Forest Biomass in Shangri-La City Based on LiDAR Technology and Other Remote Sensing Data"],"prefix":"10.3390","volume":"14","author":[{"given":"Yuncheng","family":"Deng","sequence":"first","affiliation":[{"name":"Faculty of Geography, Yunnan Normal University, Kunming 650500, China"},{"name":"Key Laboratory of Resources and Environmental Remote Sensing for Universities in Yunnan Kunming, Kunming 650500, China"},{"name":"Center for Geospatial Information Engineering and Technology of Yunnan Province, Kunming 650500, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jiya","family":"Pan","sequence":"additional","affiliation":[{"name":"Faculty of Geography, Yunnan Normal University, Kunming 650500, China"},{"name":"Key Laboratory of Resources and Environmental Remote Sensing for Universities in Yunnan Kunming, Kunming 650500, China"},{"name":"Center for Geospatial Information Engineering and Technology of Yunnan Province, Kunming 650500, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7202-646X","authenticated-orcid":false,"given":"Jinliang","family":"Wang","sequence":"additional","affiliation":[{"name":"Faculty of Geography, Yunnan Normal University, Kunming 650500, China"},{"name":"Key Laboratory of Resources and Environmental Remote Sensing for Universities in Yunnan Kunming, Kunming 650500, China"},{"name":"Center for Geospatial Information Engineering and Technology of Yunnan Province, Kunming 650500, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Qianwei","family":"Liu","sequence":"additional","affiliation":[{"name":"Faculty of Geography, Yunnan Normal University, Kunming 650500, China"},{"name":"Key Laboratory of Resources and Environmental Remote Sensing for Universities in Yunnan Kunming, Kunming 650500, China"},{"name":"Center for Geospatial Information Engineering and Technology of Yunnan Province, Kunming 650500, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jianpeng","family":"Zhang","sequence":"additional","affiliation":[{"name":"Faculty of Geography, Yunnan Normal University, Kunming 650500, China"},{"name":"Key Laboratory of Resources and Environmental Remote Sensing for Universities in Yunnan Kunming, Kunming 650500, China"},{"name":"Center for Geospatial Information Engineering and Technology of Yunnan Province, Kunming 650500, China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2022,11,17]]},"reference":[{"key":"ref_1","first-page":"1","article-title":"Temporal-Spatial Dynamics of Carbon Storage of Forest Vegetation in China","volume":"26","author":"Xu","year":"2007","journal-title":"Prog.
