Evaluation on the spillover effect of traditional agroecosystem services is helpful to improve the correct cognition of agroecosystem services and can provide scientific basis for the rational planning of regional socio-economic industrial structure and ecological security layout. Taking the Hani Terrace Heritage Area in Yunnan Province as an example, we used the unit area equivalent factor method to evaluate agroecosystem services. Aiming to clarify characteristics and value spillover of agricultural ecosystem services in the study area, we selected the market value method and the travel cost interval method to estimate the production service value and leisure tourism service value of the terraced landscape. The results showed that:(1) From 1995 to 2018, the overall change in land use in the study area was not significant, while the area of construction land increased relatively much, with a change rate of 59.3%. (2) The total value of agro-ecosystem services in the Hani Terrace Heritage Area decreased by 8.1×10⁶ yuan, with a change rate of 0.6%; the agricultural ecosystem service structure remained stable. Among the first-level service types, the value of regulation service was the largest, while among the second-level service types, the value of climate regulation service was the largest. The contribution rate of food and raw material production value was only 6%, and the value of water resource supply service was negative. (3) In 2018, the grain production service value was 0.8×10⁸ yuan, and the value of leisure tourism service was 1.3×10⁸ yuan. The eco-tourism promotes the regional sustainable development, and the terraced agricultural production landscape has obvious value spillover effect.
