Plant carbon use efficiency (CUE) reflects the assimilation ability and sequestration potential of organisms, is an important quantitative index in ecology. Therefore, investigating CUE can better understand explore ecosystem flux allocation patterns. In this paper, Wuding River Basin taken as research area. MODIS were used to calculate its spatiotemporal variations. Using remote sensing environmental indicators (RSEI) extract ecological sources, MCR model construct spatial network. By analogy with complex network theory, topological indicators, combine significance investigate relationship between these considering their significance. The results are follows: (1) average value slightly increased, overall increase southeastern part study area, minor changes southern parts, decrease western northern parts basin. (2) showed a strong positive correlation closeness centrality, betweenness harmonic negative eccentricity, while no significant was found component number.

Carbon neutrality is an important goal for addressing global warming. It can be achieved by increasing carbon storage and reducing emissions. Vegetation plays a key role in storing carbon, but it often lost or damaged, especially areas affected desertification. Therefore, restoring vegetation these crucial. Using advanced techniques to improve ecosystem structure support ecological processes, enhance soil environmental conditions, encourage growth, boost effectively. This study focuses on optimizing Ecological Spatial Networks (ESNs) revitalization regional development, employing such as the MCR model corridor construction, spatial analysis, Gephi mapping topological attributes. Various metrics were used evaluate network performance, while EFCT was applied optimize ESN maximize sinks. In Thal Desert, source patches (ESPs) divided into four modularity levels (15.6% 49.54%) five communities. The northeastern southwestern regions showed higher functionality lower connectivity, central region exhibited reverse. To structure, 27 51 corridors added 76 existing patches, including 56 forest 20 water/wetland using model. optimized resulted 14.97% improvement sink capacity compared unoptimized primarily due better functioning of wetland areas. Enhanced connectivity between components contributed more resilient stable ESN, supporting both sustainability sequestration.
