“…The classification system in this article can comprehensively reflect the change of land use functions and the transition of land use and development intensity. In addition, the land resources were classified as three land use types in the comprehensive zoning of land utilization [64]. Table 2 presents three classes of the territorial space.…”

Regional land use transitions driven by the adaptive reconciliation of existing land use conflict with socioeconomic development can lead to positive economic effects as well as new land use conflict. Although research on land use transition has progressed considerably, limited studies have explored the spatiotemporal dynamic pattern of land use conflict during the land use transition period. Previous evaluation approaches on land use conflict that mainly focus on status or potential conflict lack conflict intensity evaluation during the land use transition process. A new spatially explicit evaluation framework of land use conflict that directly examines three aspects of conflict, namely, ecological and agricultural (EAC), agricultural and construction (ACC), and ecological and construction (ECC) land conflicts based on ecological quality and agricultural suitability, is proposed in this study. The spatiotemporal dynamic pattern and driving factors of land use conflict in the Yangtze River Economic Belt of China in the period of 2000–2018 are evaluated. The results indicated that comprehensive land use conflict (CLUC) intensity slightly decreased by 9.91% and its barycenter showed a trend toward the west during 2000–2018. ACC is the most drastic conflict among the three aspects of conflict. The mean intensity of ACC reduced remarkably by 38.26%, while EAC increased by 33.15% and ECC increased by 28.28% during the research periods. The barycenter of EAC moved toward the east while the barycenter of ACC and ECC moved toward the west. The changes in the intensity and spreading pattern of land use conflict indices demonstrated the changes in the pattern of territorial space development. Total population, population density, per capita GDP, number of mobile phone users, and road density were strong drivers that influenced the land use conflict of territorial space. Multiple policy recommendations including improving territorial space planning and governance ability, and improving land use efficiency, were proposed to manage and resolve the land use conflict of territorial space. The results and conclusions of this study will help improve future regional land use policies and reduce land use conflict.

“…Human activities are closely tied to ecology and the environment. Understanding and assessing the eco-environment level is not only an important research focus in the field of energy and environment, but also critically needed by the sustainable economy and civilisation 1 . Coal is a key component of China's energy structure, accounting for 60% of the total annual energy consumption 2 .…”

The contradiction between the exploitation of coal resources and the protection of the ecological environment in western China is becoming increasingly prominent. Reasonable ecological environment evaluation is the premise for alleviating this contradiction. First, this paper evaluates the eco-environment of Ibei coalfield by combining the genetic projection pursuit model and geographic information system (GIS) and using remote sensing image data and other statistical data of this area. The powerful spatial analysis function of GIS and the advantages of the genetic projection pursuit model in weight calculation have been fully used to improve the reliability of the evaluation results. Furthermore, spatial autocorrelation is used to analyze the spatial characteristics of ecological environment quality in the mining area and plan the specific governance scope. The geographic detector is used to determine the driving factors of the eco-environment of the mining area. The results show that Ibei Coalfield presents a spatially heterogeneous eco-environment pattern. The high-intensity mining area (previously mined area of Ili No.4 Coal Mine) has the worst ecological environment quality, followed by the coal reserve area of Ili No.4 Coal Mine and the planned survey area of Ili No.5 Coal Mine. The eco-environment quality (EEQ) of the study area is affected by both human and natural factors. Mining intensity and surface subsidence are the main human factors affecting the ecological environment in the study area. The main natural factors affecting the ecological environment in the study area are annual average precipitation, elevation, annual average evaporation, NDVI and land use type. Meanwhile, the interaction effect of any two indicators is greater than that of a single indicator. It is also indicated that the eco-environment of the mining area is nonlinearly correlated to impact indicators. The spatial autocorrelation analysis shows three areas that should be treated strategically that are the management area, close attention area and protective area. Corresponding management measures are put forward for different regions. This paper can provide scientific references for mining area eco-environmental protection, which is significant for the sustainability of coal mine projects.

“…Due to rapid economic and social development and urbanization, ecological problems are becoming increasingly serious, global climate change and species extinction are ongoing, and the condition of ecosystems continues to deteriorate. The degradation of ecosystems and ecosystem services is having an irreversible impact on our societies and hindering national development, and a systematic understanding of ecosystem services is a prerequisite for addressing such scienti c issues (Gao et al 2019, Wollheim et al 2015. A systematic understanding of ecosystem services is a prerequisite for addressing such scienti c issues.…”

Monitoring changes in watershed ecosystem services is an important aspect of watershed ecological security assessment and the anchor point for research on watershed ecological protection and economic development. Current research has focused on the assessment of typical ecosystem service functions in watersheds, with relatively little research on influencing factors and their spatio-temporal change impact mechanisms. This paper presents a comprehensive analysis of the spatio-temporal variation mechanisms of ecosystem services and influencing factors in the Dongjiang River Basin(DRB) in China from 2000 to 2019. The results show that the land use structure of DRB has been stable and typical ecosystem services such as water retention, soil and water conservation, and carbon storage are slightly reduced in the past 20 years. The typical ecosystem services of the study area are influenced by topographic factors, climatic factors, and natural socio-economic factors, and are significantly related to precipitation, temperature, elevation, slope, GDP, population, and NDVI. From 2000 to 2019, the influence factors have obvious spatial and temporal heterogeneity, with the largest positive influence factor of NDVI and slope showing a diffusion enhancement trend, and the largest negative influence factor of population density showing the same trend. The overall ecosystem service function has remained stable, and the coordination between economic development and ecological protection has been good. Future regional development needs to further implement the ecological protection development strategy, focus on and implement measures to improve the ecological service function of key areas, and reduce the negative impact of population.
