Abstract: Taking Enshi Prefecture of Hubei Province as an example, a functional classification system of “productive-living-ecological space” was constructed, and the functional evolution of “productive-living-ecological space” and its response to the ecological environment was studied using the land use transfer matrix, center of gravity shift model, ecological environmental quality index model and ecological contribution ratio model. The results showed that, from 2000 to 2020, the overall trend of living space area was on the rise, the overall trend of ecological space area was decreasing, and the area of productive space showed a trend of first decreasing, and then increasing. The transfer distance of living space was the largest, followed by productive space, and the transfer distance of ecological space was the smallest. The overall ecological environment quality showed a downward trend. The transformation of agricultural production land into key ecological land and general ecological land, and the transformation of general ecological land into key ecological land were the major factors in the improvement of ecological environment quality; the transformation of key ecological land to agricultural production land and general ecological land were the major factors in the decline of ecological environment quality.

Key words: productive-living-ecological space, functional evolution, ecological environment response, ecological environment quality, Enshi Prefecture of Hubei Province
