Abstract: Abstract As an advocate of “urban ecology construction” and the capital of Fujian, an “ecological province”, the ecological quality of vegetation in Fuzhou City is crucial to the development of ecological civilization in the region. The ecological quality of vegetation in Fuzhou City was assessed by quantifying the distribution and changes in the Normalized Difference Vegetation Index (NDVI) and the Net Primary Productivity (NPP) of vegetation from 2000 to 2020 and exploring the influence of urban development on their distribution. The result shows that the multi-year average Vegetation Fraction Cover (VFC) of the region is 68%, showing a significant growth trend (0.32% yr−1), reaching 72.43% by 2020. The multi-year average NPP is 14.6 × 103 kg C·m−2·yr−1, and the vegetation carbon sequestration showed a smooth fluctuation in the last two decades. VFC and NPP are relatively low on the eastern coastal and riverine areas, while they had higher levels in the inland mountainous areas. However, the ecological quality of vegetation in urban areas is poor and showing a decreasing trend, for the effect from urbanization. The construction of ecological civilization has led to an upward trend in the overall ecological quality of vegetation in Fuzhou City, but regional economic development has caused a decline in the ecological quality of vegetation in urban areas and surrounding areas. This study provides a basis for further regional vegetation ecology research and also has important implications for balancing urban development and vegetation.
