In order to analyze the ecological spatial changes of villages before and after three adjustment da-ta,taking Baijiabu Village in Yuzhong County as the research object,the ecological source and ecological data were extracted based on the third national land survey data,and the equivalent factor method(EFM)was used to compare and analyze the data.It was concluded that the total ecosystem service value(ESV)of Baijiabu Village in Yuzhong increased by 113.82％before and after three adjustment data.The research re-sults proved that:(1)By increasing the area of farmland,woodland and grassland under permanent basic protection,the total value of ecosystem services is improved;(2)The optimization of ecological space is conducive to the promotion of village economic construction,the improvement of ecological environment,the promotion of industrial diversification,and the construction of a new pattern of ecological network.
