The core strategy for national development in the new era is the establishment of an ecological civilization. In contrast, the overall understanding of the three concerns facing rural communities in the new era is the rural revitalization strategy. The paper examines the present state of the linkage development between constructing an ecological civilization and implementing a rural revitalization strategy in rural areas. It does this by developing an evaluation index system and drawing on the theoretical underpinnings of the linkage development between the two strategies (rural revitalization strategy and ecological civilization construction). The entropy value approach is used to compute the comprehensive index and determine the weights of each index. The coupling and coordination degree models are used to measure the coordination degree and coupling correlation of the two, and the correlation factors between them are analyzed by constructing the gray correlation model. The findings indicate that overall, County A’s rural revitalization development level between 2012 and 2021 tends to be better, although overall levels are not very high. The comprehensive index of development for rural revitalization goes from 0.194 in 2012 to 0.754 in 2021. Yearly fluctuations in ecological civilization-building are evident, with the complete index of ecological civilization construction rising from 0.380 in 2012 to 0.945 in 2021. The overall trend is slowly increasing when the coupling coordination degree of 0.610 from 2015 is taken as a limit, but high-quality coordination is still a significant distance away.
