Analysis of water–carbon–ecological footprints and resource–environment pressure in the Triangle of Central China

Existing index system on the resource–environment pressure (REP) measure is mostly based on the multi-index comprehensive evaluation method. However, the selection of evaluation indices is highly affected by subjective factors, potentially resulting in poor comparability of results. With these conce...
