Vegetation, as a multi-type and multi-functional green energy, plays an important role in regional carbonemission reduction and carbon neutrality. This study carried out the concept of green and sustainable developmentin depth and constructed an emergy quantification methodology system for the multidimensional servicefunctions of vegetation ecosystems consisting of forests and grasslands based on the theory of emergy analysisand multidisciplinary integration methods. Using the theory of spatial correlation and breakpoints, we delineatedthe major ecological zones and investigated the radiation effects of typical regulating functions. Taking Luoyang,China, as an example, the results showed that the annual sequence of vegetation ecosystem service function(VES) emergy in Luoyang City showed a decreasing and then increasing trend with 2015 as the cut-off point.Early-stage Forest exploitation had profound effects, while increasing cultural benefits in later stages demonstratednational emphasis on forest research and conservation. The forest's high-quality ecological zone inLuoyang City could be found in the three southern counties of Luoning (LN), Luanchuan (LC), and Song (S). Theradiation effect encompassed the entire city, resulting in an obvious impact with a total radiation of approximately4.10E+20 sej. The high-quality ecological zone of the grassland did not appear until 2020 and is locatedin Yiyang (YY) county in central Luoyang. It benefited only the surrounding counties and had a total radiation of1.32E+18sej. However, the development trend is optimistic. The spatial pattern of vegetation should be suitablefor natural conditions, and the development strategy of localization as the driving force of the whole should be realized through the establishment of high-quality ecological zones, so as to promote harmonious coexistencebetween human and nature through green development.
