Abstract: This study proposes a systematic classification of production–living–ecological function indicators based on ecosystem services, thereby clarifying the spatial functions of villages. Based on the land use change survey data of the Jintan District in 2012 and 2018, the ecological impact of town and village layout planning in Jintan District was analysed by using a quantitative measurement model of ecosystem services. The findings revealed that the ecosystem service value (ESV) decreased by 792 million CNY in the Jintan District, with the largest decrease in water ecosystem services valued at 700 million CNY and in hydrological regulation valued at 576 million CNY. A clear regional difference in ESV was observed, with villages on the east and west coasts of Changdang Lake being higher-value areas and most villages or communities in urban areas being lower-value areas. The areas of cultivated land, construction land, and unused land have increased, while land types with higher ecosystem service value coefficients, such as wetland, water area, and grassland, have declined. The spatial pattern of production and living functions was quite similar, while there was a significant spatial aggregation characteristic of ecological functions.
