Accurate estimation of terrestrial ecosystem carbon storage and the scientific formulation ecological conservation land use policies are essential for promoting regional low-carbon sustainable development achieving goal “carbon neutrality.” In this study, FLUS–InVEST model was used to evaluate stocks Jiangsu coastal zone in China from 1995 2020 scientifically forecast changes 2030 under three scenarios: natural exploitation, protection, economic development. The results as follows: (1) From 2020, initially remained stable before declining, a trend closely linked accelerated urbanization growth Province. (2) By 2030, scenarios exhibits pattern “S1 decrease–S2 increase–S3 decrease,” with more significant increase construction compared protection scenario. (3) sensitivity varies across scenarios. scenario, is most affected by forest reduction expansion. it responsive increases non-construction land. expansion leads decrease storage. Therefore, when formulating future territorial spatial planning urban strategies, consider comprehensively, taking into account sequestration capabilities. This approach will ensure effective restoration damaged ecosystems while safeguarding robust economies societies.

Projecting Water Yield Amidst Rapid Urbanization: A Case Study of the Taihu Lake Basin

Land, Journal Year: 2025, Volume and Issue: 14(1), P. 149 - 149

Published: Jan. 13, 2025

Changes in land cover and use (LULC) can impact water availability by altering the structure functioning of ecosystems. Accurately projecting impacts LULC on yield (WY) is utmost importance for regional landscape management. Taking rapidly urbanizing Taihu Lake Basin (TLB) as an example, coupled with PLUS-InVEST model, three scenarios a natural development (ND) scenario, urban (UD) ecological protection (EP) scenario were set to simulate response mechanisms changes WY influence policy-making conservation capacity river basins. (1) During 2000 2020, experienced rapid urbanization, which was evident conversion forest cropland development. (2) From TLB’s first decreased then increased, ranging from 201.52 × 108 m3 242.70 m3. Spatially, uneven distribution pattern depth emerged, mountainous hilly regions exhibiting higher compared plain areas. Temporally, total primarily influenced precipitation, while areas increased showed certain correlation experiencing expansion construction land. (3) By 2030, TLB will continue expand under UD area EP scenario. expected vary across scenarios, highest observed followed ND exhibits lowest yield. These findings offer scientifically informed insights guidance future changes, carrying substantial effects maintaining preservation promoting high-quality TLB.

Spatiotemporal Dynamics of Ecosystem Water Yield Services and Responses to Future Land Use Scenarios in Henan Province, China

Water, Journal Year: 2024, Volume and Issue: 16(17), P. 2544 - 2544

Published: Sept. 9, 2024

Water yield (WY) service is the cornerstone of ecosystem functionality. Predicting and assessing impact land use/land cover (LULC) changes on WY imperative for a nation’s food security, regional economic development, ecological environmental protection. This study aimed to evaluate water in Henan Province, China, using high-resolution (30 m) remote sensing use monitoring data from four years: 1990, 2000, 2010, 2020. It also utilized PLUS model predict characteristics LULC evolution future trends under different development scenarios (for 2030 2050). The study’s results indicated following: (1) From 1990 2020, Province’s first increased then decreased, ranging 398.56 × 108 m3 482.95 m3. southern southeastern parts Province were high-value areas, while most its other regions deemed low-value areas. (2) types ranked terms their capacity, strongest weakest, as follows: unused land, cultivated grassland, construction woodland, water. (3) abovementioned ranked, highest lowest, based Henan’s total (in 2050) each them: high-quality scenario (HDS), business-as-usual (BAU), protection (CPS), (ES). contributes advancement services research. Its can provide scientific support resource management, sustainable comprehensive land-use planning Province.

The Effects of Multi-Scenario Land Use Change on the Water Conservation in the Agro-Pastoral Ecotone of Northern China: A Case Study of Bashang Region, Zhangjiakou City

Agriculture, Journal Year: 2025, Volume and Issue: 15(9), P. 1008 - 1008

Published: May 6, 2025

Water resource management is crucial for sustainable agricultural and ecological development, particularly in regions with complex land-use patterns sensitive eco-systems. The Bashang region of Zhangjiakou city, located the agro-pastoral ecotone northern China, an ecologically fragile area that currently undergoing significant land use climate changes. Despite importance understanding interplay between use, change, water conservation, few studies have comprehensively evaluated their combined effects on regional resources. This study addresses this gap by investigating spatiotemporal changes yield (WY) conservation capacity (WCC) under different scenarios year 2035. research employs FLUS model to predict future InVEST estimate WY WCC a natural development scenario (NDS), production (APS), protection (EPS), planning (LPS). results reveal primarily influenced precipitation, topography. finds which focus optimization, such as EPS LPS, significantly enhance Notably, LPS scenario, limits urban expansion increases amount land, provides best balance conservation. findings highlight need integrated approaches management, transitional zones. unique contribution lies its comprehensive modeling approach, combines data, analysis, valuable insights strategies.

This study takes the Beijiang River Basin in Guangdong Province as an example, examining changes land usage throughout time and space between 1980 2020. Using multidimensional ecosystem service functions loop theory, this constructs ecological constraints (ES) for Basin. Based on these constraints, ES-PLUS model is developed to simulate future cover under multiple scenarios by 2050. The results indicate following: (1) Currently, major use types are forest, cropland, grassland, accounting over 95% of area. Significant were observed 2020, including severe degradation forests grasslands, a notable expansion construction land, intense human–land conflicts, highest single dynamic degree unused at 5.67%, with comprehensive 0.18%.
