Predicting Land-Use Change Trends and Habitat Quality in the Tarim River Basin: A Perspective with Climate Change Scenarios and Multiple Scales

Land, Journal Year: 2024, Volume and Issue: 13(8), P. 1146 - 1146

Published: July 26, 2024

Under the influences of climate change and human activities, habitat quality (HQ) in inland river basins continues to decline. Studying spatiotemporal distributions land use HQ can provide support for sustainable development strategies ecological environment arid regions. Therefore, this study utilized SD-PLUS model, InVEST-HQ Geodetector assess simulate land-use changes Tarim River Basin (TRB) at multiple scales (county grid scales) scenarios (SSP126, SSP245, SSP585). The results indicated that (1) Figure Merit (FoM) values Globeland 30, China’s 30 m annual land-cover product, Chinese Academy Sciences (30 m) product were 0.22, 0.12, 0.15, respectively. A comparison datasets with different resolutions revealed kappa value tended decline as resolution decreased. (2) In 2000, 2010, 2020, 0.4656, 0.4646, 0.5143, SSP126 SSP245 scenarios, showed an increasing trend: years 2030, 2040, 2050, they 0.4797, 0.4834, 0.4855 0.4805, 0.4861, 0.4924, SSP585, first increased then decreased, 0.4791, 0.4800, 0.4766 (3) three areas improved mainly located southern northern high mountain regions around urban areas, while diminished primarily western part basin central areas. (4) At county scale, spatial correlation was not significant, Moran’s I ranging between 0.07 except 2000 2020. clear high- low-value clustering (Moran’s 0.80 0.83). This will assist planners policymakers formulating policies promote civilization basin.

Spatio-temporal analysis of litterfall load in the lower reaches of Qarqan and Tarim rivers using BP neural networks

Scientific Reports, Journal Year: 2025, Volume and Issue: 15(1)

Published: Jan. 7, 2025

Litterfall load is crucial in maintaining ecosystem health, controlling wildfires, and estimating carbon stock arid regions. However, there a lack of spatiotemporal analysis litterfall riparian forests. This study aims to estimate using BP neural network based on vegetation indices from Landsat 5 8 satellite images, inventory data, slope, distance major river tributaries. It also analyze the distribution pattern litter research area by analyzing along desert forests lower Qarqan Tarim Rivers 2001 2021. The results show that initiation ecological water transfer project has facilitated decomposition litterfall, leading an initial decline. Subsequently, gradually recovered, increase leaf input. Since 2001, initially decreased until reaching its lowest value 4.39 × 109 kg 2005, followed subsequent increase, highest 12.5 concludes conveyance promotes both litterfall. Initially, it accelerates decomposition, while later stages foster load. Meanwhile, due higher cover River compared River, basin experiences average variation.

Heartwood/Sapwood Characteristics of Populus euphratica Oliv. Trunks and Their Relationship with Soil Physicochemical Properties in the Lower Tarim River, Northwest China

Plants, Journal Year: 2025, Volume and Issue: 14(2), P. 154 - 154

Published: Jan. 7, 2025

The characteristics of heartwood and sapwood not only reflect tree growth site quality but also provide insights into habitat changes. This study examines the natural Populus euphratica Oliv. forest in Arghan section lower Tarim River, comparing P. at different distances from river, as well varying trunk heights diameters breast height (DBH). objective was to examine correlation between these physicochemical properties soil better understand ecological response strategies arid environments. Results indicated that radius, width, area, moisture content decreased with increasing height, following pattern: 0.3 m > 0.8 1.3 m. In contrast, density increased increased. Most indicators larger diameters. case a DBH less than 45 cm, difference significant (p 0.05) However, m, < 0.05). Soil analysis revealed factors such total nitrogen, available potassium, water significantly influenced physical across sites. Redundancy (RDA) further demonstrated phosphorus, were correlated sapwood, validating critical role nutrients shaping wood euphratica. These findings highlighted specific adaptations River desert environment, reflected observed relationships conditions sapwood.

Land Use Changes and Future Land Use Scenario Simulations of the China–Pakistan Economic Corridor under the Belt and Road Initiative

Sustainability, Journal Year: 2024, Volume and Issue: 16(20), P. 8842 - 8842

Published: Oct. 12, 2024

The China–Pakistan Economic Corridor (CPEC), as an important part of the Belt and Road Initiative, is great significance for promotion sustainable development in region through study land use change simulation future multi-scenarios. Based on multi-period data CPEC, this firstly analyzed spatial temporal changes CPEC from 2000 to 2020 by using GIS technology, and, secondly, simulated patterns under four scenarios, namely, natural development, investment priority, ecological protection, harmonious 2040 Markov-FLUS model with comprehensive consideration natural, socio-economic, other driving factors. results show following: (1) urban land, forest grassland increasing trend, while farmland, unutilized water area categories a decreasing trend. In terms transfer changes, most frequently transferred out conversion grassland. (2) FLUS has high accuracy simulating pattern its applicability strong can be used simulate CPEC. (3) Among different scenario strikes better balance between infrastructure construction, economic provide scientific basis management order highlight importance promoting growth protection ultimately realize development.
