The development and implementation of regional protection plans for ecosystem carbon storage services have been recognized as crucial actions mitigating global climate change. However, the supply areas sequestration in terms service flows inland regions are still less evaluated. goal this study is to identify priority-ranked sinks. Here, we conducted a case Hexi Region northwestern China proposed framework quantify priority sinks from perspective flows. Firstly, quantified demand by combining models (i.e., Carnegie–Ames–Stanford Approach model soil respiration models) with socioeconomic natural factors. Then, introduced breaking point formula estimate flow, specifically focusing on distance or range. Finally, determined based Zonation model. results showed that significantly higher values were detected Qilian Mountains, ranging 2.0 3.0 t hm−2, comparison desert oasis areas, where ranged 0 0.01 hm−2. urban rural settlements within area characterized emissions compared those Mountains deserts. flow analysis demonstrated middle northern parts area, being lower precipitation sandy landscapes, identified locations low fluxes (<1.0 hm−2). In addition, mountainous main highest sequestration, covering 8.33% total Region. Our findings highlighted importance sustaining targeted ecological practices be implemented going forward.

Lakes play a role as the sentinel of climate change. Surrounded by vast expanses barren land with limited infrastructure, there is also lack knowledge about dynamics dryland lakes. The change lake area can be effectively monitored remote sensing, and multi-source satellite altimetry datasets provide possibility to obtain long-term water level data. Using Global Surface Water Monthly Historical dataset (Hydroweb), we reconstructed time series storage changes in Xinjiang, Northwestern China, establishing empirical models based on statistical relationship between surface each lake. We further explored response results show that at Ayakkum Lake, Aqqikkol Lake Aksayquin have been undergoing an obvious expanding trend from 2000 2020, rate 3.59×108m3/a, 9.43×108m3/a 0.44×108m3/a, respectively. In plain transition zone, Ulungur showed upward tendency (0.413×108m3/a) storage, while Manas Bosten experienced shrinkage descending rates −0.1×108m3/a −0.86×108m3/a. Temperature significantly affect plateaus, especially those lakes supplied large proportion glacial meltwater. Precipitation key factor for zones. Meanwhile, extreme weather man-made factors crucial roles. To reduce risk flood drought disasters, rational regulation resources required, large-scale integrated catchment management plan avoid inadvertent trade-offs. This research provides new perspective inversion, well data support arid areas including Xinjiang.

Studies on the spatiotemporal dynamics in ecosystem carbon and water exchanges are essential predicting effects of climate change regional energy budgets. Using eddy covariance technique, fluxes were observed a typical winter wheat (WWE) an agroforest (AFE) southern Loess Plateau from 2004 to 2010. The seasonal inter-annual variability gross primary productivity (GPP), net exchange (NEE), evapotranspiration (ET), use efficiency (WUE) examined main influencing factors identified using Pearson correlation. results indicate that GPP NEE showed bimodal distribution WWE, while this was unimodal AFE. sinusoidal function did well characterization ET for both ecosystems, with determination coefficients being 0.85 0.94, respectively.

Vegetation on the Southwestern Tibetan Plateau (SWTP) is critical to ensuring ecological security and promoting regional economic social development. Here, we explored relationship between topographic factors (elevation, slope, aspect) spatial patterns in normalized difference vegetation index (NDVI) SWTP over past 20 years. The results found that NDVI was primarily influenced by elevation slope. regions with significant variations were concentrated 4500 m 5500 slopes ranging from 0° 15°. Although influence of aspect small, there a decreasing trend sunny an increasing shady slopes. Dominant conditions identified considering 230 different combinations elevation, aspect. combination parameters indicated stronger variability, notably within sections 0°–25°slopes below 5000 elevation. These findings highlight relevance topography, slope aspect, for alpine settings. information gathered this study about prevailing distribution growth state can help future restoration conservation efforts other comparable worldwide.
