Practice of general survey of pollution discharge outlets of rivers in Song-Liao River Basin

A general survey of pollution discharge outlets of rivers in Song-Liao River Basin was carefully organized by the Song-Liao Water Resources Commission, under the unified arrangement of the Ministry of Water Resources. The survey lasted for 19 months and covers four provinces or autonomous regions in the basin. 2854 pollution discharge outlets are registered and valuable information are collected. The GIS for pollution discharge outlets of rivers in SongLiao River Basin was created based on amount, distribution and feature of pollution discharge outlets, which lays a solid foundation for water resources protection of the river basin in the future.
