Abstract:

This study examines the forest ecosystem of Picea schrenkiana in the central Tianshan Mountains, Xinjiang, China. We used the functional value method and Getis-Ord Gi* hotspot analysis to quantify and visualize the spatial distribution of ecosystem service values. The results show that the total value of the ecosystem services of the Picea schrenkiana forests is 9.609 billion Yuan per year, with water conservation, carbon sequestration, oxygen release, soil conservation, and biodiversity protection as the dominant functions. Furthermore, ecosystem service value varies by age, with middle-aged forests valued the highest, followed by near-mature, mature, and young forests. Over-mature forests have the lowest total value but the highest per-unit area value. Among the forest farms, the one with the highest ecosystem service value is Nanshan Forest Farm, followed by Hutubi, Banfanggou, and Miquan Forest Farms, with the lowest value at the Xinjiang Agricultural University Practice Forest Farm. We observed significant spatial clustering of ecosystem service values across farms, with hotspots concentrated in the southwest at Hutubi and Nanshan Forest Farms. Cold spots are concentrated in the northeast at Miquan and Banfanggou Forest Farms. This study provides a scientific basis for optimizing regional ecological resource management, formulating ecological protection policy, and supporting the sustainable development of the Tianshan forest ecosystem.

Key words: Picea schrenkiana forest, spatial pattern of ecosystem service values, ecosystem services, central Tianshan Mountains
