How to measure the net effect of wetland park construction on habitat quality: A modeling approach based on spatiotemporal Difference-in-Differences
Bibliographic record
Abstract
• Integrated indices quantify wetland parks’ multifaceted environmental impacts. • ST-DID effectively evaluates habitat quality while removing regional bias. • Wetland park construction in the Weihe River shows spatial ecological spillovers. • Wetland parks boost habitat quality by replacing impervious surfaces with green land. Leveraging local natural resources to develop recreational areas constitutes a critical strategy for urban managers to enhance ecosystem service supply. However, the specific impacts of nature park construction on local habitat quality remain ambiguous, while existing evaluation methods struggle to meet practical demands. Given the complex interactions among multiple factors influencing habitat quality, establishing a scientific evaluation system faces significant challenges. This study focuses on the Shaanxi section of China’s Weihe River Basin. First, we extracted land use and habitat quality data from five time points (2000–2020) in riparian zones using remote sensing and spatial information technologies. Subsequently, we constructed multi-ring buffers along upper, middle, and lower river reaches to establish highly comparable habitat units. Finally, a spatiotemporal difference-in-differences (ST-DID) model was employed to quantitatively identify and isolate the net impact of wetland park construction on habitat quality. Key findings include: (1) The area of wetland parks within the riparian zone increased by 5,782hm 2 , with construction primarily focused on greening and supplemented by limited hardscaping, resulting in a total forest area increase of 2,137 hm 2 ; (2) The comprehensive quality index of wetland parks in the riparian zone first increased and then declined, reaching 0.491 in 2020, representing an 8% improvement compared to the lowest level in 2010; (3) ST-DID results of the comprehensive habitat quality index indicate that despite the influence of climatic factors, wetland park construction has effectively improved habitat quality, with the environmental effect in the riparian zone increasing from −0.0032 to 0.0085. This methodology provides a novel analytical framework for assessing the ecological impacts of nature-based urban development initiatives.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
