[Objective] The impacts of land use change on the ecosystem service value of various natural process were studied

in order to provide scientific basis for rational utilization of land resources and ecological security protection of the basin.[Methods] Based on the change of land use transformation

this paper analyzed the change of land use and the change of ecosystem service value in Yongjiang River basin under the influence of human activities from 1980 to 2015.[Results] ① The decrease of cultivated land and the increase of construction land were the main characteristics of land use change in Yongjiang River basin

whose degree of land use is rising. The land use types showed complicated mutual transformation

and the largest transfer area was from the conversion of cultivated land to construction land. ② During the past 35 years

the dynamic degree of land comprehensive utilization was 0.42%. The single dynamic degree of construction land use was the largest

and the reduction of cultivated land area was the greatest. ③ In terms of time

the total value of ecological services in the Yongjiang River basin increased first and then decreased

and increased continuously before 1995

but decreased continuously afterwards. ④ At the spatial level

the total value of ecological services showed a decreasing trend from southwest to northeast.[Conclusion] The transformation of land use in Yongjiang River basin was intense

and the rapid change of land use has aggravated the degradation of ecosystem function.
