Multiple pollution treatments for Dianchi Lake by means of geographical engineering

In order to understand why there have been no obvious effects of pollution treatment of Dianchi Lake for a long time,and to analyze the main causes of Dianchi Lake pollution,multiple pollution treatments for Dianchi Lake were explored.According to the natural geographical condition of reverse flow and the current results of treatments in Dianchi Lake,an integrated system consisting of geographical engineering as the main component,along with other treatment methods,was established.The pollution problem could be solved effectively by changing the exit location of Dianchi Lake and preventing the lake from being polluted by wastewater from the Kunming urban area.
