Abstract

Accounting relating to natural resource assets is an important component of China’s ecological civilization construction program. Although the southeastern part of Qinghai-Tibet Plateau has abundant forest resources, surveys aimed at quantitative accounting of forest resources assets are constrained by difficult field conditions. Given the lack of forest classification data in Motuo County, Tibet, a study was conducted to gather detailed classification data derived from the Google Earth Engine platform as well as information on the physical quantities and values of these assets, and their stocks and flows, to develop a forest resource balance sheet of this county. The balance sheet comprised a summary sheet on the forest resources of Motuo County, an accounting table depicting the values of forest resource assets, a quantified scale measuring excessive depletion of forest resources, and a scale indicating the ecological value of forest resource assets. The balance sheet of forest resources in Motuo County, was analyzed along with changes in the county’s forests during the accounting period. In 2015, forest resources in Motuo County covered an area of 27,007.27 km2 compared with 25,596.89 km2 in 2020, indicating a degree of decrease in the area of forest resources. The ranking of the total value of forest resources comprising various tree species, in descending order, was broad-leaved mixed forest, other coniferous forests, fir, spruce, alpine pine, oak, birch, Yunnan pine, and cypress. The total values of the ecological service functions of forest resources in Motuo County in 2015 and 2020 were, respectively, 127.781 billion yuan and 123.692 billion yuan, with the soil conservation function providing the greatest value, and the air purification function providing the least value. During the period 2015–2020, the total value of forest resource assets in Motuo County increased from 1,601.038 billion yuan in 2015 to 1,664.358 billion yuan in 2020, reflecting a corresponding improvement in the county’s performance relating to investments in forest resource management. Evidently, forest resources have played a positive role in promoting economic and social development and improving residents’ lives.
