Correlation matrix showing the relationship between the tourism urbanization level of the Yellow River Basin and ecosystem services from 2000 to 2020. Note The ecosystem services include Water Yield (WY), Soil Conservation (SC), Habitat Quality (HQ), and Carbon Sequestration (CS). The subsystems analyzed are Urbanization Services (US), Tourism Services (TS), Environment Services (ES), and Tourism Urbanization (TU). The correlation coefficient values are shown by a color gradient, where red denotes a positive correlation and blue denotes a negative correlation.
