[Objective]The construction of nature protected areas(NPAs)is an important means to promote the construction of ecological civilization and the high-quality development of ecological environment. The study of the spatio-temporal characteristics of NPAs can deepen the understanding of its historical process, resource endowment and function positioning, and has an important guiding significance for the high-quality development of NPAs. [Methods]The global Moran index, standard deviation ellipse and kernel density estimation were used to analyze the spatial and temporal distribution characteristics of the nature reserves established in the lower reaches of the Yellow River between 1980 and 2020. [Results] In terms of spatial distribution, NPAs spread in a northeast-southwest direction, and their distribution center of gravity had generally shifted 88.199 km to the southwest over the past 40 years. The overall aggregation of NPAs had been increasing, with the most aggregation in the mountainous hills of south central Shandong Province and the low mountainous hills of east Shandong Province, forming two high-density areas similar to the division sign ‘÷' and ‘bimodal', respectively. In terms of development history, the study area had experienced three stages: initial exploration, steady development, and standardized development, and gradually shifted from focusing on quantitative growth to quality improvement. In terms of influencing factors, topography and geomorphology, water and heat conditions, species diversity, and vegetation cover were important factors affecting the spatial distribution and resource endowment of NPAs. Policy orientation and the improvement of ecological protection awareness were important factors leading to the increase in the quantity and quality of NPAs. [Conclusions] In order to promote the high-quality development of NPAs, ecological cities in the lower reaches of the Yellow River region should be planned based on the distribution pattern of NPAs, special ecological tourism should be developed, and ecological resources should be integrated from the point to the surface in the whole region. The results of the study can provide reliable suggestions for the high-quality development of NPAs in the lower reaches of the Yellow River.
