The study of its production-living-ecological space （PLES） transformation and its carbon storage effect is of great significance for realizing space optimization and regional sustainable development from a low-carbon perspective. Based on the land use data of Gansu Province in 2000， 2010， and 2020， we measured the spatio-temporal evolution characteristics of the PLES. The PLUS model was used to simulate the PLES in 2030 and 2060 under the three scenarios of natural evolution， economic development， and ecological priority， and the InVEST model was used to calculate its carbon storage. The results show that： ① The ecological space occupied the largest proportion and had the widest distribution. The living space occupied the smallest proportion， showing a scattered distribution， with more in the south than in the north. The production space was mostly distributed near the living space. The transformation of PLES was more drastic， mainly the transformation between \"forest-field-grass-sand\". ② The spatial distribution of PLES in the three scenarios in 2030 and 2060 was basically similar to that in the historical period. Ecological space decreased under the natural evolution and economic development scenarios and increased under the ecological protection scenarios. ③ From 2000 to 2020， carbon stocks showed a \"U\" trend of first decreasing and then increasing in time. The change of carbon storage in both the natural evolution and economic development scenarios showed a \"U\" trend of first decreasing and then increasing， while the carbon storage in the ecological protection scenarios showed a continuous increasing trend， and the carbon storage was the highest among the three scenarios. ④ The high-value and hot-spot areas of carbon storage were concentrated in the Qilian Mountains， Gannan Plateau， and Longnan Mountains， while the low-value and cold-spot areas were mainly distributed in the desert and Gobi areas of the Hexi Corridor.

Kernel density estimation， spatial autocorrelation， and spatial Markov chains are used to characterize the spatial and temporal evolution of the level of high-quality energy development， and the driving factors are explored with the help of Tobit regression models. The results show that： ① China's high-quality energy development level demonstrated an upward trend in fluctuation， but China's high-quality energy development level overall was still at a low level and tended to cluster. ② China's energy quality development level presented 'high south and low north' characteristics， and in the spatial distribution of the phenomenon of significant spatial correlation， the spatial spillover effect was obvious. The traditional Markov chain probability transfer matrix showed that the type transfer of the high-quality development level of provincial energy had stability， and there was a phenomenon of 'club convergence' . The spatial Markov chain probability transfer matrix showed that the Matthew effect existed in the high-quality development level of provincial energy， indicating that geographical factors played an important role in the dynamic evolution of high-quality energy development. ③ There was spatial and temporal heterogeneity in the effects of the drivers of the level of high-quality energy development. Economic development level， education level， technology level， and environmental regulation level were the key factors to promote high-quality energy development， while population structure and transportation infrastructure level inhibited high-quality energy development.

In recent years， in the face of the pressure of food demand caused by population growth， China has promoted cultivated land protection as a basic national policy and formulated and implemented a series of strategies for cultivated land protection and balanced control. Because of this， as the world's largest developing country， China has successfully fed 22 % of the world's population with only approximately 9 % of the world's arable land resources. However， factors such as urban construction land expansion， land degradation， and climate change still pose severe challenges to agricultural production. Henan Province， as the core area of national grain production， or 'China granary'， plays an important role. In order to ensure national food security， Henan Province has put forward the agricultural space development strategy of implementing the spatial layout of the national agricultural industry， improving the scale and intensive level of grain production， and guiding the development of agricultural modernization. At the specific implementation level， it is key to formulate relevant cultivated land zoning control strategies according to local conditions. However， due to the lack of research on the spatial and temporal evolution of cultivated land productivity， it is still impossible to get rid of the reality of taking administrative divisions as the control unit. Therefore， it is of great significance to explore the spatial and temporal differentiation characteristics of cultivated land use in Henan Province and the influencing factors of cultivated land productivity changes， so as to scientifically formulate the control strategy of cultivated land zoning， to implement the strategic pattern of national main functional areas， to keep the bottom line of land space security， and to ensure national food security. Based on this， this study constructs the transfer matrix of cultivated land use based on China's annual land cover data set and introduces the landscape pattern index of cultivated land to evaluate the spatial and temporal differentiation characteristics of cultivated land space in Henan Province from 2000 to 2020， and then the reasons for its change were analyzed. At the same time， using the net primary production （NPP） data set， Theil-Sen Median + Mann-Kendall trend analysis， Hurst index analysis， coefficient of variation analysis， partial correlation analysis， and partial correlation coefficient were used to explore the evolution of cultivated land productivity in Henan Province and quantify the impact of climate factors and human activities on cultivated land productivity.

Studying the spatiotemporal relationship between the two is of great significance for promoting green and sustainable development. Therefore， in the context of the \"dual carbon\" goal and the construction of ecological civilization， Shanxi， as a coal-producing province， was taken as the research area， based on land use and socio-economic data from 2000 to 2020， using spatial autocorrelation analysis methods to explore the spatiotemporal evolution characteristics and interaction laws of carbon emissions and ESV. The results indicate that： ① From 2000 to 2020， the main land types in Shanxi Province were cultivated land， grassland， and forest land. The area of construction land and forest land showed an increasing trend， while the area of other land types showed a decreasing trend. ② The net carbon emissions from land use in Shanxi Province have been increasing year by year， from 34.65 million tons in 2000 to 124.80 million tons in 2020. The high value areas of land use carbon emissions intensity were mainly concentrated in the central region and continued to extend to the surrounding areas， while the low value areas were mainly distributed on the edges of various cities， and their area continued to decrease. ③ The ecosystem service value in Shanxi Province was 269.13 billion yuan in 2000 and 264.69 billion yuan in 2020， with a slow decline in value. Forest and grassland had the highest contribution rates to ESV. The spatial distribution of ESV varied significantly， with significant annual changes. ④From 2000 to 2020， there was a significant negative correlation between land use carbon emission intensity and ESV intensity in Shanxi Province. The stronger the land use carbon emission intensity， the weaker the ESV intensity， and it passed the p-value test.

In the winter wheat summer maize rotation planting area in northern Henan， four treatments including no fertilization （CK）， high nitrogen application （N1）， optimized nitrogen application （N2）， and biochar-based fertilizer （TF） were set up through field positioning experiments. High-throughput sequencing technology was used to study the changes in soil fungal community composition and its relationship with soil physical and chemical properties， enzyme activity， and crop yield after long-term application of biochar-based fertilizer.
