From traditional to balanced: The upgrade of dietary structure leads to increased pressure on cultivated land ecological compensation
摘要
The evolution of food consumption patterns, driven by economic development and improved living standards, has significantly influenced the utilization of cultivated land. This study, based on the transformation of dietary structure as the basis for ecological compensation of cultivated land, breaks through the traditional compensation framework oriented by the consumer end. Based on the cultivated land demand of 18 cities in Henan Province from 2015 to 2023, a quantitative compensation model was constructed using the non-market value of cultivated land as its foundation. The results indicate: (1) From 2015 to 2023, the demand for cultivated land exhibited a fluctuating upward trend, with an overall surplus. (2) During the study period, the non-market value of cultivated land showed a trend of rising first and then declining, reaching a peak of CNY 92343.80 million in 2021, and showing a characteristic of decreasing from southeast to northwest. (3) By 2023, Henan Province transitioned from a cultivated land ecological compensation area to a payment area. (4) Compared to the dietary structure in 2023, under the balanced dietary pattern, the demand and deficit area for cultivated land increased by 1530.81 thousand hectares and 583.22 thousand hectares, respectively, and the ecological compensation pressure of cultivated land intensified. This study investigated the interplay between cultivated land ecology and economy in the context of shifting food consumption demands. It elucidated the ecological compensation associated with changes in dietary patterns and offered a theoretical foundation for cultivated land protection.
