The encroachment on ecological led to severe problems and threatened stability security Analyzing characteristics future multi-scenario expansion its impacts patterns (ESP) can provide guidance for formulating ecologically sustainable management control Policies. Our study focuses Changsha-Zhuzhou-Xiangtan (CZX) agglomeration as area establishes an ESP. Additionally, a cellular automata (CA) was used simulate under three scenarios (i.e., natural development scenario, conservation scenario). subsequent analysis evaluates their impact simulation results indicate that from 2020 2030, CZX will undergo rapid scenario characterized by outward growth surrounding existing land.

Vegetation change has a non-negligible role in the impact of ecosystem services (ESs). Quantitative assessment vegetation is basis for sustainable regional development. Using Chinese Loess Plateau (LP) as study area, this firstly analysed spatial and temporal characteristics used Geodetector model to reveal driving mechanism. Next, applied InVEST quantitatively assess four carbon storage, habitat quality, soil conservation water yield, explored service balance through type transfer. The results showed that (1) there was trend towards an increase area all types, with sparse being most pronounced. Areas damaged were concentrated urban peripheral areas, well wasteland bare ground. (2) Annual precipitation, types cumulative afforestation ratio main drivers on LP. (3) Restoration woodland enhanced quality retention LP, while yield decreased by 31.66%. restoration did not enhance services. This may provide reference management ecosystems.

In 2015, the Sustainable Development Goals (SDG) replaced Millennium (MDG), providing guidance and direction for future development of countries around world. Both MDG SDG have established multiple indicators to achieve environmental sustainability. However, few studies compared changes in ecological environment during two periods. Therefore, this study selected seven major river basins China as area comprehensively assessed ecosystem service importance (ESI) within different periods based on six services, including habitat quality, soil conservation, water yield, carbon storage, grain production, aesthetic landscape. Specifically, from 2000 2015 2020 were used represent periods, respectively. The results showed that overall ESI an increasing trend both proportion extremely important reached 20.39% 2020, mostly distributed Yangtze River basin Pearl basin.

Assessing the effects of future urban expansion on ecosystem services (ESs) is essential for sustainability cities worldwide. Nonetheless, evaluating these ESs remains challenging due to uncertainties associated with socioeconomic development and intricate nature expansion. In this research, we initially integrated localized Shared Socioeconomic Pathways (SSPs) Land Use Scenario Dynamics-urban (LUSD-urban) model project Yangtze River Delta agglomeration (YRDUA). Subsequently, quantified impacts utilizing Integrated Valuation Tradeoffs (InVEST) model. The outcomes indicate that land in YRDUA projected expand by 1,020.19–12,282.04 km2 at a growth rate 3.71–44.67% from 2022 2050. Simultaneously, habitat quality (HQ), carbon storage (CS), water retention (WR), air purification (AP) are expected decline 0.34–4.24%, 0.48–5.82%, 0.39–4.75% 0.20–2.45%, correspondingly. Most importantly, primary cause ES losses conversion cropland land, accounting more than 90% total losses. results offer crucial contextual insights support synergistic policies urbanization ecological conservation under increased climate change.

Recent centuries have witnessed a considerable economic growth, but also been accompanied by ecological deterioration which has led to the utility decline in every hard-won material wealth. Here we proposed comprehensive framework for detecting these growth expenses, combining ecosystem services chain with economics principles. Remote sensing products, biophysical process modeling, and inferential geostatistics were comprehensively used tracing quantity quality of natural capital, total amount, fairness human well-being both aspects last two decades China. We find that although capital condition most parts China are rising, they declining economically developed regions where vast majority people lives. Furthermore, this is unequal, affecting different due spatial mismatch between population services. Further promoting China's environment-friendly industrial system transaction products may help alleviate inequity well-being.

Abstract Most tide‐dominated estuaries worldwide are among the morphodynamic shrinking types heavily disturbed by anthropogenic interventions like embankments and reclamations. A typical example is North Branch (NB), northern first‐order distributary of Yangtze (Changjiang) Estuary, showed a rapid alteration from river‐dominated to character in less than 50 years after intensive reclamations, resulting serious shrinkage, thus attracted great concern its evolutionary fate. Here, we explored this issue based on historical bathymetry data hydro‐morphodynamic modeling examine morphology‐hydrology interactions suggested equilibrium re‐adjustment mechanism Results demonstrated geomorphological resilience for estuary, evolving preliminary estuarine dynamic Although reclamation could destabilize system, leading temporary positive feedback between tidal pumping morphology shrinking, driving estuary vanishing quickly short time. substantial loss intertidal areas, changing geometry highly‐curved bank highly‐constrained channel, weakened flood asymmetry NB, which turn altered sediment dynamics deposition erosion. Such negative process tends drive toward new morphology. The discovered nonlinear supported evidence system efficiency adjustment, was substantially gained during first 30 years, then stayed low entropy production minimum work state, indicating more efficient equilibrium. If further preservation policies implemented, NB expected continue long time future.
