The evolutionary model of construction land serves as a fundamental pillar in national spatial development and planning research. However, previous studies have overlooked the "climbing" mode on three-dimensional terrains. To address this issue, utilizing elevation data use from 2010 to 2020, study employs slope analysis, intensity spatio-temporal transformation, PLUS elucidate expansion process driving forces urban Chongqing both two-dimensional perspectives. findings indicate that: (1) From topographical standpoint, between 2012, gradually expanded towards low-slope areas, whereas 2012 it progressively extended into high-slope regions. (2) Regarding type conversion patterns, shift arable demonstrates systematic inclination, while other transformations exhibit absolute or relative tendencies. Conversely, also displays pattern. (3) Since 2010, growth has transitioned slow-equilibrium rapid-disequilibrium with an expanding disparity. (4) Most areas maintain relatively stable conditions without significant jumps transitions observed. (5) is primarily influenced by terrain, river, tunnel, rail transit, factors. outcomes can provide scientific foundations decision-making references for rational similar cities characterized mountainous landscapes intersected rivers.

Seasonal Variation in the β‐Diversity of Periphytic Algae and Its Response to Landscape Patterns in the Chishui River, a Naturally Flowing Tributary of the Upper Yangtze River

Ecology and Evolution, Journal Year: 2025, Volume and Issue: 15(2)

Published: Feb. 1, 2025

Understanding biodiversity is essential for preserving the stability of river ecosystems. However, impact landscape configurations and seasonal variations on within undammed ecosystems remains unexplored. Therefore, we selected Chishui River-a naturally flowing tributary upper Yangtze River-for a survey periphytic algae. The present study focuses fluctuations in β-diversity algae River its correlation with surrounding patterns. Our findings indicate that there substantial influence community structure these ecosystem. Concurrently, observed turnover component predominantly contributes to β-diversity. In light findings, recommend conservation measures be implemented across entire basin safeguard regional biodiversity. Redundancy analysis elucidated water temperature, conductivity, pH were primary environmental drivers shaping algal communities. Furthermore, additional analyses using random forest model indicated fragmentation complexity key determinants Notably, number patches was strongly correlated It important highlight maintaining an optimal balance between their size crucial enhancing ecosystem's capacity preserve summary, our provide insights into interplay land-use practices complex riverine environments, thereby offering scientific foundation management

Response of Ecosystem Service Value to LULC Under Multi-Scenario Simulation Considering Policy Spatial Constraints: A Case Study of an Ecological Barrier Region in China

Land, Journal Year: 2025, Volume and Issue: 14(3), P. 601 - 601

Published: March 13, 2025

Analyzing the complex dynamics of land use, accurately assessing ecosystem service values (ESVs), and predicting future trends in use ESVs alterations within spatial constraints policies are essential for policymaking advancing sustainable development objectives. This study analyzed use/land cover (LULC) changes Yunnan Province from 2005 to 2020. Policy were incorporated into scenario simulations, an improved equivalent factor method, Markov-PLUS model, global autocorrelation, Getis-Ord Gi* method applied predict analyze LULC under different scenarios 2030. The findings revealed following: (1) Forests grasslands dominant categories YNP, with notable patterns recorded between (2) total area increased by CNY 8.152 billion during this period, exhibiting initial decline followed gradual recovery. (3) Simulations 2030 indicated that natural would lead most extensive urbanization, while ecological conservation yield greatest increase ESVs. In contrast, only farmland led food production-related ESVs, but resulted lowest among three scenarios. These results contribute understanding impacts on provide insights formulating scientifically sound effective protection policies.

Temporal-spatial variation of regulating ecosystem services and analysis of driving factors in Hainan Tropical Rainforest National Park, China

Frontiers in Earth Science, Journal Year: 2025, Volume and Issue: 13

Published: March 13, 2025

The establishment of national parks is a critical measure for natural ecological protection in China, significantly contributing to biodiversity conservation and regional sustainable development. However, the analysis temporal-spatial variations ecosystem services within parks, along with factors influencing these variations, remains largely overlooked. This gap limits effectiveness refined management parks. Using Hainan Tropical Rainforest National Park (HTRNP) as case study, this study integrates geospatial ArcGIS InVEST model evaluate regulating (RESs) from 2000 2020 at 5-year intervals. examines temporal evolution patterns spatial distribution RESs, utilizing LightGBM identify primary driving services. findings reveal following: (1) Temporally, RESs exhibit significant fluctuations, trend “initial decline followed by subsequent rise”. Climate regulation accounted highest proportion 61.4%, water soil retention. (2) Spatially, eastern central regions are slightly higher than those western region, demonstrating consistency across different years. HTRNP show strong clustering effect (Moran’s I > 0.5, Z 2.58), hotspots (H-H) regions, cold spots (L-L) northern regions. (3) In terms factors, including annual precipitation (PRE) potential evapotranspiration (PET) alongside socio-economic such land use cover (LULC) Human Footprint Index (HFI), make marginal contributions RESs. Specifically, demonstrate strongest correlation LULC, positive PRE, negative correlations PET HFI. explores dynamic changes providing scientific guideline future planning effective decisions HTRNP.

Le’an Town, located in the southwest of Qingchuan County, Guangyuan City, Sichuan Province, boasts a unique geographical position. The town’s terrain is complex, and its geological environment fragile. Multiple phases tectonic movements have resulted numerous cracks faults, making area prone to landslides, debris flows, other disasters. Additionally, heavy rainfall fluctuating groundwater levels further exacerbate instability mountains. Human activities, such as overdevelopment deforestation, significantly increased risk Currently, methods for landslide prediction Town are limited; traditional techniques cannot provide precise forecasts, study largely covered by tall vegetation. Therefore, this paper proposes method that combines SBAS-InSAR technology with dynamic changes land use hydrological conditions. used obtain surface deformation information, while land-use condition data incorporated analyze characteristics potential influencing factors areas. innovation lies high-precision monitoring capability integration multi-source data, which can more comprehensively reveal environmental area, thereby achieving accurate predictions development. results indicate annual subsidence rate most areas ranges from −10 0 mm, indicating slow subsidence. In some areas, exceeds −50 mm per year, showing significant slope aspect differences, reflecting combined effects structures, climatic conditions, human activities. It evident conditions impact on occurrence development landslides. utilizing cross-verifying it techniques, consistency identified be enhanced, improving results. This provides scientific basis early warning disasters has important practical application value.
