Karst water is an important element of underground water in Beijing and is characterized by abundance of supply and high quality. Karst water is an ideal water source for alleviating the supply and demand discrepancy of water resources and providing water for the city. The water environment of karst landforms is relatively fragile and requires additional attention. So the rational use of karst water requires the establishment of scientific and effective models of water quality evaluation. Taking several karst water distribution areas as examples, this study established an index and standard of estimation according to set pair analysis (SPA). The study subsequently built the corresponding connection and determined the weighting factor according to the degree of association. Basic indicators of water quality were processed and analyzed through comprehensive evaluation principles to provide a foundation for the actual management and the rational use of karst water distribution areas in Beijing.

Abstract


Karst water is an important element of underground water in Beijing and is characterized by abundance of supply and high quality. Karst water is an ideal water source for alleviating the supply and demand discrepancy of water resources and providing water for the city. The water environment of karst landforms is relatively fragile and requires additional attention. So the rational use of karst water requires the establishment of scientific and effective models of water quality evaluation. Taking several karst water distribution areas as examples, this study established an index and standard of estimation according to set pair analysis (SPA). The study subsequently built the corresponding connection and determined the weighting factor according to the degree of association. Basic indicators of water quality were processed and analyzed through comprehensive evaluation principles to provide a foundation for the actual management and the rational use of karst water distribution areas in Beijing.
