Land-use/land-cover change (LUCC) is an important factor affecting carbon storage. It of great practical significance to quantify the relationship between LUCC and storage for regional ecological protection sustainable socio-economic development. In this study, we proposed integrated framework based on multiobjective programming (MOP), patch-level land-use simulation (PLUS) model, valuation ecosystem service trade-offs (InVEST) model. First, used InVEST model explore spatial temporal evolution characteristics in Hangzhou from 2000 2020 using land-cover data. Second, constructed four scenarios natural development (ND), economic (ED), (EP), balanced (BD) Markov chain MOP, then simulated distribution land cover 2030 with PLUS Third, was predict 2030. Finally, conducted a correlation Hangzhou’s delineated zoning Hangzhou. The results showed that: (1) artificial surfaces grew significantly, while cultivated decreased significantly 2020. overall trend decrease storage, changing areas were characterized by local aggregation sporadic distribution. (2) surfaces, water bodies, shrubland will continue increase up 2030, grassland decrease. BD scenario can effectively achieve multiple objectives (3) decline EP have highest which mitigate loss. (4) inextricably linked cover, high–high concentration low–low concentration. study provide decision support other cities Yangtze River Delta region.

Remote Sensing, Journal Year: 2022, Volume and Issue: 14(19), P. 4751 - 4751

Published: Sept. 23, 2022

Land use and land cover (LULC) contribute to both carbon storage emissions. Therefore, regulating the LULC is an important means of achieving neutrality under global environmental change. Here, West Liaohe River Basin, a semiarid watershed, was taken as case study. Based on assessment emissions induced by from 2000–2020, we set up three different coupled shared socioeconomic pathway (SSP) representative concentration (RCP) scenarios (SSP119, SSP245, SSP585), 2030–2060, optimize LULC. Then, patterns each scenario were simulated using patch-generating simulation (PLUS) model, corresponding changes in compared analyzed. It found that, since 2000, with expansion forest, cropland, construction land, well degradation grassland, have significantly increased, but increase lower than that The simulations revealed when LULC, mainly including protection ecological such forest grassland western southern edges basin, control management cropland northeast central parts there will be significant reduction 2030–2060. This indicates zone-based measures rational regulation can achievement study area. Supported results this study, direct decision-making basis for policy promote regional sustainable development undertaken basin. also provides reference low-carbon other regions.

Unraveling carbon stock dynamics and their determinants in China's Loess Plateau over the past 40 years

Ecological Indicators, Journal Year: 2024, Volume and Issue: 159, P. 111760 - 111760

Published: Feb. 1, 2024

Synergies and trade-offs among land use covers (LULCs) pose considerable uncertainties in achieving the dual carbon goals for China's Loess Plateau (CLP). In this context, we unraveled stock dynamics induced by cover change (LUCC) CLP over past 40 years using satellite-derived annual LULC maps InVEST model. Then, mixed measures were employed to quantify global local responses of both natural anthropogenic factors. We found that approximately a total 5.58 × 109 Mg was stored CLP's ecosystems 2019. Chronologically, showed slight decrease from 1980 2019 due extensive LUCCs linked socioeconomic activities. Specifically, density loss rate accelerated urban–rural-wild continuum (RUWC) types with higher human activity intensity, such as villages urban, while it decelerated woodlands, croplands, where intensity is lower. Moreover, gain wildlands accelerating. Finally, revealed primarily influenced variables have responded diversely drivers space.

A Coupled InVEST-PLUS Model for the Spatiotemporal Evolution of Ecosystem Carbon Storage and Multi-Scenario Prediction Analysis

Land, Journal Year: 2024, Volume and Issue: 13(4), P. 509 - 509

Published: April 12, 2024

In investigating the spatiotemporal patterns and spatial attributes of carbon storage across terrestrial ecosystems, there is a significant focus on improving regional sequestration capabilities. Such endeavors are crucial for balancing land development with ecological preservation promoting sustainable, low-carbon urban growth. This study employs integrated InVEST-PLUS model to assess predict changes in ecosystem under various use scenarios within Chengdu cluster, vital region Central Western China, by 2050. The results indicate following. (1) A linkage between dynamics changes: over two decades, 7.5% decrease arable was observed alongside 12.3% increase areas, leading an 8.2% net reduction storage, equating loss 1.6 million tons carbon. (2) Carbon variations four scenarios—natural (NDS), (UDS), farmland protection (FPS), (EPS)—highlight impact differing developmental conservation policies Chengdu’s reserves. Projections until 2050 suggest further 5% NDS without intervention, while EPS could potentially 3%, emphasizing importance strategic planning policy. research provides solid theoretical foundation exploring relationship further. summary, findings highlight necessity incorporating considerations into strategies. not only sheds light current challenges but also presents method forecasting mitigating urbanization effects services, thus supporting sustainable goals.

Interregional Flows of Embodied Carbon Storage Associated with Land-Use Change in China

Published: June 27, 2024

With the continuous expansion of regional trade, interregional teleconnections have an increasingly pronounced impact on changes in carbon storage caused by land use China. Current research this area remains remarkably limited, however. This study employs land-use data, density and a multiregional input–output model to precisely quantify embodied flow spatial patterns We found that interprovincial trade China accounts for 34.9 percent total storage, with cropland (44.9 percent) woodland (43.6 representing highest proportions within their categories. Inner Mongolia, Heilongjiang, Tibet were be most externally driven terms land-use-related outflows exceeding 2,000 Tg C. Beijing, Tianjin, Shanghai, other hand, shown consume up 90 inflows, showcasing strongest external dependence. Additionally, Hunan (1,300.5 C), Hubei (863.4 Henan (1,534.6 Shanxi (2,223.6 C) are provinces where significant, exerting greatest influence China's storage. international export decreased 3,964.7 C during period, (1,516.8 grassland (1,505.7 being primary declining types. Interestingly, as utilization efficiency continues rise, over half seen increase value, while corresponding has declined. The findings not only unveil complex dynamics distribution at work but also provide practical insights directions achieving neutrality goals.
