What is Long-term terrace change and ecosystem service response in an inland mountain province of China about?

The exploration of terrace change and its associated ecosystem services (ESs) provides invaluable insights into the intricate interplay between engineering initiatives and environmental conditions. This understanding is crucial in designing strategic plans for environmental management. However, how terraced fields area change and influence ESs over an extended period at a regional scale remain relatively unknown. To bridge this knowledge gap, this study focused on terraces in Gansu Province (a typical inland mountain province), Northwestern China, by dividing the study area into seven regions, the quality and value benefits of unit area, the overall and cumulative of terraces were calculated for each region in Gansu province based on remote-sensing data, meteorological data, terraced area and benefits data. In this regard, the distribution, spatiotemporal changes and ESs associated with terraced fields in Gansu were examined from 1990 to 2020. The results show that: (i) terraces with the area of 2.20 × 10 4 km 2 accounts for 81.34 % of counties(districts) of Gansu province in 2020, mainly located in the loess hilly and gully region (82.72 %). (ii) From 1990 to 2020, the terrace are
