[Synergistic Impact of Climate Change and Human Activities on Vegetation Coverage in the Economic Belt on the Northern Slope of the Tianshan Mountains].
摘要
. The spatial distribution was heterogeneous, presenting a "high in the northwest-southeast axis and low around the edges" pattern, with low fractional vegetation coverage (FVC ≤ 0.2) being dominant, accounting for 62.45%. ② During the same period, both improvement and degradation trends coexisted, and the Hurst index analysis indicated that 51.87% of the region may face potential risks of vegetation degradation in the future. ③ The geographical detector analysis showed that land use was the most significant driving factor for FVC variation, with a q-value of 0.670, making land use one of the key factors influencing FVC change. ④ The relative contribution rates of climate change and human activities to the variation in fractional vegetation coverage were 15.54% and 84.46%, respectively. In conclusion, future ecological construction should focus on strengthening the role of human activities in promoting the increase of fractional vegetation coverage, while enhancing the monitoring and protection of existing vegetation to prevent degradation trends.
