The systematic evaluation of the water environment in Yellow River basin is a critical scientific basis for achieving goals ecological protection and high-quality development. In this study, five-dimensional comprehensive framework (“quality–quantity–space–flow–biota”) consisting 19 indicators was constructed. entropy method catastrophe progression were innovatively combined to solve limitations traditional models characterizing nonlinear relationships within systems. results indicated that basin’s overall index 0.032, classified as “good”. However, spatial differentiation significant, showing step-by-step degradation characteristic “upstream > downstream midstream”. Gansu Province (0.028), Ningxia Hui Autonomous Region (0.026), Shaanxi (0.024), Shanxi (0.020) rated “poor” urgently need be regulated. core problems are shortage (Gansu, Ningxia), quality deterioration (Shaanxi, Shanxi), fragmentation aquatic space (Shanxi, Shaanxi). findings study provided quantitative tool differentiated governance which could directly support decision-making needs “zoning control precise policy implementation” “Outline Plan Ecological Protection High-quality Development Basin”.

Unveiling the Spatial Variation in Ecosystem Services Interactions and Their Drivers Within the National Key Ecological Function Zones, China

Remote Sensing, Год журнала: 2025, Номер 17(9), С. 1559 - 1559

Understanding the spatial differentiation of ecosystem service (ES) interactions and their underlying driving mechanisms is crucial for effective management enhancing regional landscape sustainability. However, comprehensive analyses effects key influencing factors on ES remains limited, especially regarding nonlinear heterogeneity. We assessed validated five in National Key Ecological Function Zones (NKEFZs) China—net primary productivity (NPP), soil conservation (SC), sandstorm prevention (SP), water retention (WR), biodiversity maintenance (BM). By integrating optimal parameter geographical detector with constraint line methods, we further explored complex responses to across different functional zones. The results showed that most exhibited significant synergistic clustering. In contrast, widespread trade-off clustering was detected pairs related WR, mainly distributed Tibetan Plateau, northeast China, Southern Hills region. Due improvement ES, overall synergies enhanced from 2000 2020. dominant zones influenced a non-stationary manner, same potentially showing diverse effect types sub-regions. Additionally, role configuration sub-regions specific interaction (e.g., WR-NPP SP zones), suggesting potential achieving multi-ES through planning without altering composition. This research provides valuable insights into understanding offers scientific foundation implementation ecological protection restoration plans.

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, Год журнала: 2025, Номер 15(9), С. 1008 - 1008

Опубликована: Май 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.
