Abstract Using the remote sensing image data of 1987, 2000 and 2010 in the Shiyanghe River Basin as the basic data and the ecology economic coordination degree evaluation model (EEH), we evaluated the coordinated level of economic development and ecological environment in the Shiyanghe River Basin with modified ecosystem service value equivalency factors per unit area. The results showed that: (1) ecosystem service value of the studied area presented a downward trend, and the losses of ecosystem service value were mainly concentrated in the phase of 2000-2010; (2) the counties with increased value of ecosystem services were distributed in the upstream of the basin, while among all the counties/districts with reduced values, the ecosystem service value of Minqin county declined the most; (3) the EEH value of the studied area was -0.0174, so the development level of ecological and economic was at a low conflict level, from the point view of spatial distribution, the counties/districts with low coordination degree were mainly distributed in the upstream and midstream of the basin, while those with low degree of conflict were mainly distributed in the downstream of the basin; (4) in the two phases of the studied area, there were five coordinate transformations: low-low conflict; low-low coordination; low conflict-low coordination; low coordination-low conflict; low coordination-moderate conflict.
