Abstract
In order to deeply understand the status quo of regional farmland ecosystem service value and promote the sustainable development of regional farmland, selected farmland in Fujian Province as the research object to study the spatio-temporal changes of its ecosystem service value, and further analyzed the influencing factors of farmland ecological service in Fujian Province through the grey relational model.The results showed that:（1）The value of farmland ecosystem service in Fujian province increased during the study period, but fertilizer and pesticide produced great negative environmental value;（2）As for the spatial difference of farmland ecosystem service value in Fujian province in 2018, nanping has the highest positive service value and the highest per capita service value, Longyan has the highest service value per unit area, and Zhangzhou has the highest negative service value.（3）Among the factors influencing the value of ecological services, water resource utilization, crop planting area and effective irrigation area are the main factors influencing the change of the value of farmland ecosystem services, while the plastic film area and the total power of agricultural machinery have less influence.
