Abstract
Climate change and land use change caused by human activities have a profound impact on ecological security. Simulating the spatio-temporal changes in ecosystem service value and ecological security patterns under different carbon emission scenarios in the future is of great significance for formulating sustainable development policies. This study quantified the four major ecosystem services (habitat quality, water retention, soil erosion, and carbon storage) in Northeast China (NC), identified ecological source areas, and constructed a stable ecological security pattern. The results show that the spatial patterns of soil erosion, carbon storage, water retention, and habitat quality, the four major ecosystem services in NC, are relatively stable in the next 30 years, and there is no significant difference from the current spatial pattern distribution. The SSP1-2.6 carbon emission scenario is a priority model for the development of NC in the next 30 years. In this carbon emission scenario, the NC has the largest ecological resources (191,177 km2) and the least comprehensive resistance value (850.006 × 10-4). At the same time, the relative resistance of the corridor in this scenario is the smallest, and the area of the mandatory reserve pinch points is the least. The ecological corridors in the SSP1-2.6 scenario form a network distribution among the ecological sources, connecting several large ecological sources as a whole. This study fills the knowledge gap in building a stable ecological security pattern in NC under the background of global change, and provides a scientific basis for the decision-making of regional ecological security and land resource management.

Abstract
Tourism ecological security is the basic guarantee for the sustainable development of tourist sites, Huizhou Cultural and Ecological Reserve is an important area for the im-plementation of ecological protection in China, and it is of great significance to carry out research on tourism ecological security. The study adopted the DPSIR model to construct a comprehensive evaluation index system for tourism ecological security and used entropy value-TOPSIS and ArcGIS software to analyze the inter-annual changes and spatial change characteristics of tourism ecological security in the study area. The results show that: firstly, the comprehensive index of tourism ecological safety in the study area from 2010 to 2021 shows a trend of "decreasing-increasing" and an overall increasing trend; secondly, all the sub-systems show an increasing or stabilizing state in recent years during 2010-2021; the state and response sub-systems show an increas-ing or stabilizing state in recent years; and the state and response sub-systems show an increasing trend in recent years. Secondly, all the subsystems showed an increase or stabilization in recent years between 2010 and 2021, and the state and response sub-systems are the main systems to improve the ecological safety of tourism in the study area; thirdly, the difference in the level of ecological safety of tourism in each county of the study area increased and then narrowed from 2010 to 2021, and the change of safety level usually shifted between neighboring levels, and the probability of transfer-ring across the levels was relatively small. , Shexian County, Yixian County, Qimen County, Tunxi District, and the tourism eco-safety level of Huangshan District, Hui-zhou District, Jixi County, and Xiuning County increased at a faster rate than other counties. The study further extends the scale to the district and county level, tries to explore the relevant factors affecting the ecological security of tourism, and proposes countermeasures for the sustainable development of the study area based on the re-sults, which will bring some reference value to the ecological governance and policy formulation of this kind of research.

ENVIRONMENTAL MONITORING AND ASSESSMENT 2023; 195:749.

Abstract
During the construction process of railways in the plateau region, various types of pollution sources can have serious or even irreversible impacts on the plateau ecology. To address pollution source treatment during the construction process, protect the ecological environment along the railway, and maintain the ecological balance, we collected geological and environmental data and analyzed the influencing factors of pollution sources. Taking sewage as the main research subject, we propose a new method based on the Analytic Hierarchy Process (AHP)-cloud model to classify the pollution source treatment level, establish an index system, and select the ecological environment level, sewage rate, and pollutant characteristics as the three main influencing factors. Finally, we divide the pollution source treatment level into I, II, and III, corresponding to V1 = {I-level} = {high impact}, V2 = {II-level} = {moderate impact}, and V3 = {III-level} = {low impact}. Based on the comprehensive factor weight analysis and the field engineering conditions of the studied railway in the western plateau of China, we classify the pollution source treatment level of six tunnels and propose treatment suggestions for each level. To advance the efficient implementation of environmental protection during the construction of the plateau railway, we propose three policy recommendations that can positively contribute to environmental protection and green development. This work provides theoretical and technical guidance for the treatment of pollution sources in the construction of the plateau railway, which also serves as a significant reference for other similar projects.

THE SCIENCE OF THE TOTAL ENVIRONMENT 2023; 855:158940. [PMID: 36152856 DOI: 10.1016/j.scitotenv.2022.158940] [Citation(s) in RCA: 14] [Impact Index Per Article: 14.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 07/22/2022] [Revised: 09/18/2022] [Accepted: 09/18/2022] [Indexed: 06/16/2023]
Abstract
The land use and land cover change (LUCC) associated with climate change and human activities is supposed to exert a significant effect on ecosystem functions in arid inland regions. However, the role of LUCC in shaping the spatio-temporal patterns of ecosystem services and ecological security remain unclear, especially under different future LUCC scenarios. Here, we evaluated dynamic changes of ecosystem services and ecological security pattern (ESP) in the Hexi Regions based on LUCC and other environment variables by integrating morphological spatial pattern analysis (MSPA), entropy weight method and circuit theory. Our result showed that the LUCC was generally stable from 1980 to 2050. Compare to 2020, the land conversion under natural growth (NG), ecological protection (EP) and urban development (UD) scenarios in 2050 has changed by 10.30 %, 10.10 %, and 10.31 %, respectively. The forest, medium-cover grassland and water increased in the EP scenario, and construction land and cropland greatly expanded in the other two scenarios. Ecosystem services grew larger in the EP scenario by 2050 in comparison with the NG and UD scenarios. The ESP in the Hexi Regions has obvious spatial differences during 1980-2050. The larger ecological sources and less resistance corridors were mainly distributed in the central and eastern of the Hexi Regions with high ecosystem services. Conversely, fragmented ecological sources and larger resistance corridors were mostly located in the western regions blocked by sandy land, bare land or mountains. Compared to 2020, the area of ecological sources and pinch points under the EP scenario in 2050 increased by 4.10 × 103 km2 and 0.31 × 103 km2, respectively. The number of ecological corridors reduced while the length and resistance increased apart from the EP scenario. Our results highlighted the importance of ecological protection in shaping the LUCC, which further enhances the integrity of ecosystem and ecological security.
