This study evaluates the value of ecological products in Yellow River Basin, China within "Two Mountains" theory framework prioritizing conservation and quality growth. Major basin cities were analyzed to quantify product flows from 2011 2020 using an entropy approach assessing rural dynamics, financing, governance, manufacturing, economic structuring. Entropy valuations datasets 38 municipalities showed aggregated values increased ¥5.73 trillion ¥6.54 2020. Spatial disparities observed with mid-upper regions exhibiting significantly higher than lower basinal areas. The novel valuation methodology provides localized quantification aligned China's sustainability initiatives. multivariate panel regression model shows that while development agricultural fiscal support negatively impact value, environmental regulation advanced industrial structures have a strong positive influence. Furthermore, quantile analysis reveals heterogeneities distribution explanatory variables across different quantiles value. offers comprehensive view various factors dynamics influencing Basin. concludes by emphasizing importance balancing realization growth, particularly coastal These findings provide valuable insights for optimizing advancing protection high-quality

The Yellow River Basin is rich in coal resources, but the ecological environment fragile, and degradation of vegetation exacerbated by disruption caused high-intensity mining activities. Analyzing dynamic evolution Henan section its areas over long term run reveals regional offers a scientific foundation for region’s sustainable development. In this study, we obtained time series Landsat imageries from 1987 to 2023 on Google Earth Engine (GEE) platform utilized geographically weighted regression models, Sen (Theil–Sen median) trend analysis, M-K (Mann–Kendall) test, coefficient variation (CV), Hurst index investigate cover based kNDVI (the normalized difference index). This used explore spatial temporal characteristics future development trend. Our results showed that (1) value exhibited fluctuating upward at rate 0.0509/10a 2023. region aligned closely with overall section; however, annual each area consistently remained lower than displayed degree fluctuation, predominantly characterized medium–high variability, moderate high fluctuations accounting 73.5% total.

Introduction The implementation of cultivated land quality protection is fundamental for ensuring the sustainable use resources, and it inevitable choice maintaining balance agricultural ecology promoting long-term healthy development agriculture. Methods Based on survey data from 927 grain family farms in 13 major grain-producing areas China, this paper empirically tests effects participation cooperatives behavior by using a logit model, an ordered probit model propensity score matching method. Results results show that has significant positive effect degree farms. A series robustness reveals conclusion study does not change. Heterogeneity analysis probability implementing significantly increased, was greater with younger farmers, farmers lower education level, non-party members, larger scale operation, longer establishment years, labor force, or provincial demonstration.
