英文摘要Terrestrial ecosystems have experienced profound changes due to the combined influence of climate change and human activities, leading to local degradation of vegetation and ecosystem services. However, the contributions of climatic factors and human activities to vegetation dynamics and their differences among ecosystem types remain largely unknown, compromising the scientific basis for type-differentiated sustainable management. To this end, we mapped annual kNDVI to quantify vegetation dynamics, employed a partial derivative function to decompose the relative contributions of climate and human activities to kNDVI changes, and analyzed their differences across natural-anthropogenic-integrated ecosystem types in China from 2001 to 2022. The results show that China's average kNDVI exhibited an overall increasing trend of 0.16%/a, with 4.7% of the area showing degradation. Among different ecosystem types, urban/township and cultivated land ecosystems had larger degraded areas (19.1% and 3.2%), while mixed farmland/forestland and mixed farmland/pastureland ecosystems had larger greening areas (81.1% and 78.0%), respectively. The kNDVI trends were positively correlated with temperature for all ecosystem types but differentially correlated with precipitation and solar radiation. Precipitation and human activities were the dominant factors influencing kNDVI changes, with contribution rates of more than 40% and 25% respectively, and a total contribution of more than 80%. However, contributions of temperature and solar radiation to kNDVI changes were generally below 10% across all ecosystems. Along with human footprint increased, the impacts of climate changes on kNDVI in artificial or semiartificial ecosystems were more stable than that in natural ecosystems, which indicates that natural ecosystems are more vulnerable to human disturbance. As human activities have unevenly altered climatic impacts on vegetation dynamics across ecosystem types, sustainable ecosystem management strategies such as ecological protection and restoration and protected area construction should pay more attention to type- and regionaldifferentiated underlying mechanisms, especially for more fragile natural ecosystems. In terms of specific measures, we suggest optimizing the layout of nature reserves, integrating ecological projects and promoting public participation to enhance the effectiveness of ecosystem vegetation protection.
