Distribution Characteristics of the Alpine Treeline and Vegetation Response to Climate Change of Taibai Mountain, China

Climate change significantly affects global forest ecosystems, and the alpine treeline is sensitive to warming. The data using high-resolution remote sensing images during four periods from 1987 2020 at Taibai Mountain are extracted. dynamic process of response vegetation near climate analyzed. results showed that was primarily distributed in range 2266-3692 m, average elevation a trend “rising-decreasing.” treelines sunny slopes were much higher than shady slopes, highest values typically appeared on steep 15-35°. Vegetation temperature changes, it displays synchronous increase decrease. However, there lag precipitation approximately one year, rising temperatures not conducive growth. will be dominated by unsustainable improvement future, exists risk continuous degradation northern slopes. warm humid growth above treeline.
