Assessing Surface Water Hydrological Connectivity and Spatiotemporal Evolution in Xinjiang (2000–2020)

Land Degradation and Development, Journal Year: 2025, Volume and Issue: unknown

Published: March 23, 2025

ABSTRACT Assessing hydrological connectivity is crucial for maintaining the health and integrity of wetland river‐lake ecosystems in arid regions as it plays a key role watershed ecological balance sustainable development. We utilized Joint Research Center's global surface water dataset. combined these data with indices circuit theory to analyze spatiotemporal evolution Xinjiang from 2000 2020. determined that an increase area generally enhances regional connectivity. However, fragmentation bodies may affect quality potential by increasing number connecting pathways. The expansion patches alter their connectivity, near large catchment areas often serving critical connection points. Additionally, we found impacts climate change human activities led corridors 427 527 2020, surrounding pinch points barrier showing trends. This study provides new evidence 2020 identifies priority protecting enhancing network Our results provide scientific basis optimizing conservation framework networks Xinjiang, aquatic ecosystems, accelerating environmental restoration networks.

Optimization Strategies for Ecological Security Pattern Based on the Remote Sensing Ecological Index in Yunnan Province, China

Land Degradation and Development, Journal Year: 2024, Volume and Issue: unknown

Published: Dec. 13, 2024

ABSTRACT Current research on ecological security pattern (ESP) primarily emphasizes preserving the overall connectivity of ecosystems. However, a significant gap exists in systematically identifying ecologically degraded areas and optimizing regional networks. In particular, southwestern region China, characterized by complex terrain diverse ecosystems, lacks comprehensive dynamic changes ESP. This study uses machine learning to identify primary drivers spatial patterns remote sensing index (RSEI) establishes corresponding resistance surface. Through integrating morphological analysis with circuit theory, we developed “point‐line‐area” combined ESP for Yunnan Province proposed recommendations protection. Results show that 66 sources were identified 2000, decreasing 52 2023, area increasing from 29,730.57 43,122.06 km 2 , southwest. Additionally, 69 corridors 2000 total length reducing 5934 4813 km. Ecological improved significantly; however, northeast remain sparse, contributing pressure. Furthermore, 71 65 pinch points, along 46 53 barriers, identified. Overall, source increased significantly, substantial improvements, especially such as Kunming economic circle exhibit limited functionality. Future efforts should focus expanding buffer zones restoring enhance stability.

Evaluation of the Social Effects of Wetland Ecological Restoration in China: From the perspective of satisfaction and perception of residents around Poyang Lake in Jiangxi Province

Research Square (Research Square), Journal Year: 2024, Volume and Issue: unknown

Published: Dec. 4, 2024

This paper focuses on the social effect assessment of ecological governance Poyang Lake wetland in Jiangxi Province. By distributing and collecting 1,098 valid questionnaires to surrounding residents, this deeply explores feedback residents’ satisfaction recognition effectiveness measures. Through comprehensive use regression analysis descriptive statistical methods, discusses impact management measures life quality, environmental protection awareness community well-being. The study found that project was widely praised, overall residents as high 87.5%, reflecting a significant effect. Further revealed affected by multiple factors, including age, education, quality improvement quality. Residents’ cognition function is multi-dimensional profound, but they still need strengthen popular science education deep-level functions such species protection. Based research conclusion, three policy suggestions are proposed: first, government should enhance public protection; second, pay attention win-win ecology people's livelihood, promote harmonious coexistence development; third, improve relevant infrastructure, facilities, scientific monitoring legal construction, lay solid foundation for sustainable utilization resources.
