Spatial and temporal distribution of biomass in dense regions of Tianshan spruce in Xinjiang, 2002-2017

As the main body of terrestrial ecosystems, forests account for over 65% of the fixed carbon content each year, and forest biomass accounts for about 90% of the total biomass of terrestrial ecosystems. They play an important role in regulating global carbon balance and slowing down the rise of greenhouse gas concentrations. Tianshan spruce, as an important forest resource in Xinjiang, has significant ecological and economic value. Constructing its biomass spatiotemporal dataset can provide basic data for the assessment of regional carbon sequestration potential, and provide scientific basis for the protection and sustainable management of Tianshan spruce forests. The dataset includes text data and image data, among which Excel text data collects the structural data of the dense area of Xinjiang Tianshan spruce in 2002, 2007, 2012, and 2017 for each sample plot; Grid image data includes terrain data such as altitude, remote sensing data such as normalized vegetation index, meteorological data such as annual average precipitation, annual average runoff depth, annual average easterly wind speed, and biomass distribution map of spruce dense areas. The comprehensiveness of these data is crucial for revealing the growth trends and changes of spruce in the Tianshan Mountains. It not only has important scientific value and practical application potential in the fields of ecological protection and climate change research in the Tianshan Mountains of Xinjiang, but also provides valuable data resources for researchers in the area of ecosystem management and related fields.
