Regional Carbon Storage Dynamics Driven by Tea Plantation Expansion: Insights from Meitan County, China

Land, Journal Year: 2025, Volume and Issue: 14(2), P. 227 - 227

Published: Jan. 22, 2025

Over the past two decades, tea plantation area in Meitan County, China, has expanded nearly 30-fold, driving significant land use and cover changes (LUCC) with unclear impacts on regional carbon storage. This study uses PLUS-InVEST model to analyze LUCC storage from 2000 2020 predict future by 2060. Results show a decline total 3977.83 × 104 t 3960.85 2020, primarily due reductions cultivated grassland. Although forest plantations increased, overall trend remained negative. Multi-scenario simulations indicate that sustainable development scenario (SDS) mitigates loss, decrease of 31.53 t, compared larger natural (NDS) economic (EDS) scenarios. Under SDS scenario, grassland increased while construction expansion was controlled. emphasizes optimizing agricultural management enhance sequestration protect ecosystems, highlighting need for balance between ecological protection County.

Simulation of Land Use Change and Ecosystem Service Value Dynamics under Ecological Constraints in Anhui Province, China

International Journal of Environmental Research and Public Health, Journal Year: 2020, Volume and Issue: 17(12), P. 4228 - 4228

Published: June 13, 2020

Land use change has a significant impact on the structure and function of ecosystems, transformation ecosystems affects mode efficiency land use, which reflects mutual interaction relationship. The prediction simulation future can enhance foresight planning, is great significance to regional sustainable development. In this study, changes are characterized under an ecological optimization scenario based grey (1,1) model (GM) (FLUS) model. addition, ecosystem service value (ESV) Anhui Province from 1995 2030 were estimated revised estimation results indicate following details: (1) FLUS was used simulate layout in 2018, where overall accuracy high, indicating that applicable for simulating change; (2) spatial types stable cultivated highest proportion. most characteristic area continues decrease while built-up expand; (3) ESV predicted increase future. regulating largest contributor, water type with proportion ESV. These findings provide reference formulation development policies environment.

Quantitative Assessment for the Spatiotemporal Changes of Ecosystem Services, Tradeoff–Synergy Relationships and Drivers in the Semi-Arid Regions of China

Remote Sensing, Journal Year: 2022, Volume and Issue: 14(1), P. 239 - 239

Published: Jan. 5, 2022

Ecosystem services in arid inland regions are significantly affected by climate change and land use/land cover associated with agricultural activity. However, the dynamics relationships of ecosystem natural anthropogenic drivers still less understood. In this study, spatiotemporal patterns Hexi Region were quantified based on multiple high-resolution datasets, InVEST model Revised Wind Erosion Equation (RWEQ) model. addition, trade-offs synergistic among also explored Pearson correlation analysis bivariate spatial autocorrelation, redundancy (RDA) was employed to determine environmental these interactions. The results showed that most had a similar distribution pattern an increasing trend from northwest southeast. Over past 40 years, have improved significantly, water retention soil 87.17 × 108 m3 287.84 t, respectively, sand fixation decreasing 369.17 104 t. Among services, strong detected, while found be weak, significant heterogeneity Region. synergies Qilian Mountains 1.02 1.37 times higher than those Corridor, respectively. Human activities exacerbate between consumption exception carbon storage. particular, there tradeoffs food production retention, habitat quality oases which is rapid population growth cropland expansion. Additionally, precipitation, temperature vegetation increased over four decades, increases contributed enhancements storage, quality, production. Nevertheless, amount decreased, probably reduction wind speed decades. Our highlighted importance wetting resource management enhancement mitigation for regions.

How to Account for Changes in Carbon Storage from Coal Mining and Reclamation in Eastern China? Taking Yanzhou Coalfield as an Example to Simulate and Estimate

Remote Sensing, Journal Year: 2022, Volume and Issue: 14(9), P. 2014 - 2014

Published: April 22, 2022

Carbon sequestration in terrestrial ecosystems plays an essential role coping with global climate change and achieving regional carbon neutrality. In mining areas high groundwater levels eastern China, underground coal has caused severe damage to surface ecology. It is of practical significance evaluate predict the positive negative effects land reclamation on pools. This study set up three scenarios for development Yanzhou coalfield (YZC) 2030, including: (1) no activities (NMA); (2) after (NRM); (3) (MR). The probability integral model (PIM) was used subsidence by YZC use cover (LULC) 2010 2020 were interpreted remote sensing images. Based classification damage, LULC different future simulated integrating various social natural factors. Under scenarios, InVEST evaluated storage its temporal spatial distribution characteristics. results indicated that: By would have 4341.13 ha disturbed activities. NRM scenario be 37,647.11 Mg lower than that NMA scenario, while MR 18,151.03 higher scenario. Significantly, Nantun mine reduce loss 72.29% due measures. a significant correlation, lead fragmentation sink. method accounting predicting proposed this can provide data support planning enterprises carbon-neutral government departments.
