Abstract:

Wetland parks are crucial to China's natural protection system. Strengthening the construction and management of national wetland parks holds immense importance for effectively protecting wetland resources and harnessing the full ecological potential of wetlands. Focusing on the national wetland parks in the Yellow River Basin of China, this study employs kernel density estimation, hot spot analysis, standard deviation ellipse, and a geographical detective model to investigate the spatiotemporal differentiation, center of gravity evolution, and driving factors of wetland parks in 2010, 2015, and 2022. The results include the following: (1) In 2010, wetland parks in the Yellow River Basin presented a “double core and multiple points” density feature, evolving into a “multi-core and continuous patch” distribution trend in 2015 and 2022. The number and area of parks greatly increased, underscoring their growing role in regional economic development and ecological protection. (2) From 2010 to 2022, the spatial center of gravity of national wetland parks moved 247.31 km to the northeast, revealing a distinct “northeast-southwest” directional feature in its distribution pattern. Interbasin differences highlighted the largest movement of spatial center of gravity in wetland parks in the middle reaches of the Yellow River and the smallest movement in downstream provinces. (3) Natural environmental factors have a limited impact on the number and distribution of wetland parks, whereas social and economic factors decisively influence wetland protection, restoration, and park construction. Notably, the per capita regional gross domestic product and the digital elevation model have the greatest effect on the dimensions of social and natural driving, respectively.
