Net ecosystem productivity (NEP) serves as a crucial indicator for assessing carbon sequestration capacity in terrestrial ecosystems. However, the mechanism underlying spatiotemporal variations of tropical artificial forest ecosystems remains unclear. In this study, we developed data-driven semi-empirical model utilizing machine learning to simulate NEP rubber plantation and extended its application Hainan Island leveraging remote sensing reanalysis data. We analyzed direct indirect effects climate factors on through numerical simulation structural equation model. Furthermore, quantified impact area by calculating contribution rate. The results reveal that accurately captures trends seasonality gross primary (GPP) (R2=0.88, RMSE=1.19 g C m−2 day−1) respiration (RECO) (R2=0.87, MSE=0.94 day−1). Over past 19 years, exhibited an insignificant downward trend, with higher during rainy season compared dry season. Rubber central region primarily act weak sources, while those surrounding them predominantly function sinks (carbon sources/carbon ≈ 6.74%). Among factors, changes water condition exerts dominant influence (−66.03%); but different categories (precipitation relative humidity) have opposite (negative precipitation positive atmospheric humidity). Additionally, expansion cover contributed 4.01% NEP. research findings could provide basis managing improving plantations.

The karst region of southwest China showed a significant increase in vegetation cover and carbon stocks under the implementation series ecological restoration projects. However, relative contribution projects to terrestrial sequestration context climate change has yet be well quantified. Here, we used Community Land Model (CLM4.5) investigate trend net ecosystem productivity (NEP) attribution multiple environmental factors during 2000–2018. result that ecosystems with increasing NEP covered about 46% study region, which were mainly located peak forest plain colliculus cluster depression middle-high hill region. simulation experiments suggested land use associated caused large 53% trend, followed by CO 2 fertilization (72%), while nitrogen deposition minor negative effects. Especially, induced 100 pilot counties rocky desertification control project was significantly higher than other area. Moreover, moderate high levels efforts invested into recovery led larger (0.66 gC/m /yr 0.48 ) low level (0.22 ). Our results highlight important role enhanced China, recommend comprehensive assessment for policymaking.

Understanding the net ecosystem productivity (NEP) is essential for understanding functioning and global carbon cycle. Utilizing meteorological The Advanced Very High Resolution Radiometer (AVHRR) remote sensing data, this study employed Carnegie–Ames–Stanford Approach (CASA) Geostatistical Model of Soil Respiration (GSMSR) to map a monthly vegetation NEP in China from 1982 2020. Then, we examined spatiotemporal trends identified drivers changes using Geodetector model. mean over 39-year period amounted 265.38 gC·m−2. Additionally, average annual sequestration 1.89 PgC, indicating large sink effect. From 2020, there was general fluctuating increasing trend observed NEP, exhibiting an overall growth rate 4.69 gC·m−2·a−1. analysis revealed that majority region China, accounting 93.45% entirety, exhibited NEP. According analysis, precipitation change rate, solar radiation altitude were key driving factors rate. Furthermore, interaction between demonstrated most significant

ABSTRACT China's terrestrial carbon sink, quantified by net ecosystem productivity (NEP), has exhibited significant yet spatially heterogeneous growth over the past four decades, driven climate change, land use transitions, and ecological restoration policies. However, nonlinearity of NEP enhancement its coupling mechanisms with dynamic patterns remain poorly understood. This study integrates linear trend analysis, ensemble empirical mode decomposition, boosted regression tree (BRT) modeling to systematically unravel nonlinear characteristics trends (1981–2019) their landscape‐mediated drivers across ecoregions. Key findings reveal that: (1) While 43.75% area showed a increase in NEP, only 13.46% monotonic (Trend IN ), whereas 16.46% displayed reversals DE‐TO‐IN highlighting dominant dynamics. (2) Land pattern indices (LUPI)—spanning fragmentation (PD), dominance (LPI), connectivity (CONTAG), shape complexity (AWMPFD), diversity (SHDI)—demonstrated divergent trajectories: South China Tibetan Plateau (TP) experienced increasing (PD increases) alongside declining (CONTAG decreases), while Northwest (NWC) inverse patterns, reflecting region‐specific anthropogenic pressures. (3) Trend regions (e.g., NWC TP) were governed LPI CONTAG, where threshold exceedance (slope > 0) stabilized accumulation. The reversal relied on PD AWMPFD, initial declines edge effects < preceded recovery. Notably, responses LUPI gradients U‐shaped thresholds = monotonically but shifts zones, underscoring legacy historical landscape configurations. By bridging theory this advances understanding how multiscale regulate sequestration, offering actionable insights for adaptive management support “dual carbon” goals.
