Current Problems and Protection Countermeasures for Drinking Water Sources in Kunming City

Focused on the reality of declining of water environment quality, in the Kunming city, the serious of point source pollution and other major problems were found through surveyed main water supply source and analyzed characteristics of water resources, water environment quality, water supply security and conservation status. There were some problems, such as the vulnerability of water source environment, the increasing of water supply pressure were pointed out. Long-term governance combined with recent governance was proposed for conservation objectives by taking temporary solution and permanent cure, engineering control and biological control. Besides, to ensure the sustainable development of modern economy and society and the long-term stability in II - III class of water source quality, the protection countermeasures and suggestions, such as speeding up the water source protection engineering construction, establishing and perfecting the city water resources strategic reserves system and emergency water supply project, improving main forest ecological environment effectively, establishing surface water source physical and biological isolation protective engineering, building green ecological buffer, were put forward in combination with the new rural construction to build gas pool, small sewage purification treatment with the rural living garbage dump in the villages and towns surrounding of the reservoir, developing agricultural water-saving irrigation, reducing chemical fertilizer and pesticide apply content, taking the comprehensive advance of soil and water conservation engineering as the core of farmland management, effective control of incoming sediment and point source pollution.
