Study on Water Resource Vulnerability Evaluation of Hani Terrace Core Area in Yuanyang, Yunnan

AbstractThrough the defining and perfection of water resource vulnerability concept, it establishes the water resource vulnerability evaluation index system and evaluates the water resource vulnerability of Hani Terrace core area in Yuanyang, Yunnan by adopting analytical hierarchy process (AHP) and synthetic index method and the results show that in seven years, the water resource of Hani Terrace core area in 2003, 2005, 2006 and 2007 is vulnerable relatively, the water resource in 2008 and 2009 is vulnerable moderately, the water resource in 2001 is invulnerable relatively and the water resource vulnerability order from high to low is 2003 > 2006 > 2005 > 2007 > 2008 > 2009 > 2001
