Human activities have had a significant impact on ecosystems. Studying landscape patterns and ecosystem services (ES) at the village scale based land use cover (LULC) is essential in addressing current issues. Based GF images, paper selects ecosystems of karst desertification control (KDC) as research object. It uses pattern index, topographic position index (TPI), value equivalent method to conduct spatial temporal analysis service (ESV) cycle (2015–2020). The results show that: 1) forest land, orchard construction increase, dryland grassland decrease. shows an aggregated state, with spreading connectivity increasing while fragrant diversity decreasing. 2) total increased by CNY 63.45 × 10 4 , regulating cultural rise supply support decline. 3) With TPI, inversely U-shaped, remaining increases. This study provides case about areas for village-scale research.

Introduction Realizing the value of ecological products (EP) is great significance to comprehensively promote green transformation China’s economy. With increasing demand consumers for green, environmental protection and health, tendency people’s consumption (GC) has been triggered. Based on theory sustainable development ecosystem services, this paper constructs relevant econometric models deeply discusses influence mechanism demand-side GC behavior E p realization (EPVR). Methods This obtains reliability data from statistical reports yearbooks, innovatively index system EPVR whose comprehensive indexes are measured by entropy weight TOPSIS method. In analysis stage, STATA software was used unit root test, cointegration multicollinearity test descriptive statistics. On basis, regression carried out constructing a two-way fixed effect model, mediating moderating model. Results discussion (1) The level generally not high with national average 0.156 in study area. area significantly different 0.311; (2) From results significant positive EPVR, passed series robustness tests; (3) influential mechanism, further affects affecting supply willingness EP, advancement industrial structure rationalization structure.

This phenomenon generally occurs in areas around metropolitan areas, manifesting transformation or reconstruction spaces. As result, many types tertiary industry spaces utilizing land for activities have emerged. We analyze connotations spatial from perspective production innovatively propose that transformed space is an ecological product, which includes three practice: space, consumption residential space. study facilitates urban–rural integration common prosperity. Given lack analysis products, especially products (e.g., B&Bs other spaces), this aims explore value expression driving factors based on geo-visual (spatially visualizing) analytical tools looking at 10361 Jiangsu Zhejiang Provinces China typical examples.

At the 75th session of United Nations General Assembly, China formally proposed goal achieving carbon peak by 2030 and neutrality 2060, which is called dual-carbon strategy. In this study, we incorporated strategy perspective into ecological product value (EPV) evaluation. The EPV sum final service provided regional ecosystems for human production life. A significant uncertainty exists in evaluating EPV. To bridge gap, explored quantitative evaluation index system based on conducted an empirical analysis relating to four subindexes (ecological protection, products neutral capacity transformation, value, realization safeguard mechanism). nine provinces Yellow River basin 2020 was measured. results showed that total score relatively low, average scores protection level, capacity, transformation guarantee mechanism were all at a low level. Overall, level realize good. However, poor. From spatial perspective, roughly upstream region > downstream midstream basin. Finally, corresponding countermeasures suggestions are put forward according comprehensive subindexes.
