Abstract:
【Objective】 The aim of this study is to examine the landscape patterns of various forest types in Urumqi, analyze the fundamental ecological features of urban forests, and investigate the spatial distribution characteristics of carbon storage and carbon density in these forests.
【Methods】 This article focused on the arbors of urban forests as the research subject, utilized remote sensing technology combined with field survey data, employed biomass conversion methods to calculate carbon stocks, and utilized ArcGIS software and Fragstates 4.2 software to calculate landscape pattern indices.
【Results】 The results showed that the chest diameter range of Urumqi urban forest trees was mainly distributed between 4 cm and 14 cm, while tree height was predominantly distributed in the intervals of 3-5 m and 6-8 m.In Urumqi, the urban forest stored a total of 348.57×10
3 t of carbon, with scenic recreation forests having the largest carbon storage size, followed by road forests, ecological public welfare forests, affiliated forests, and production and operation forests.The carbon density was the highest in production and operation forests, followed by affiliated forests, scenic recreation forests, road forests, and ecological public welfare forests.The carbon density exhibited a pattern of decrease followed by increase from the center to the north, and a decrease towards the south.Carbon storage was found to be greater in the southern region than in the northern region.
【Conclusion】 The urban forest landscape of Urumqi is predominantly shaped by the process of urbanization.The dominant forest structure in Urumqi consists of young and middle-aged forests, indicating significant ecological development potential.The spatial distribution of carbon density is directly linked to the arid oasis environment and unique topography.
