Using AHP-MATLAB/GUI To Analysis And Evaluation Of The Vulnerability Of Yuecheng Reservoir

Yuecheng reservoir is located in Hebei and Henan Anyang County at the junction,is a large sea Henan department was on controlling water conservancy project. At anytime the rapid development of society, in addition to bear significant Yuecheng reservoirfor flood control and disaster mitigation function outside, still take the city water supply,irrigation and other various tasks.In recent years, with the increase of upstream runoff and water, the incoming ofYuecheng reservoir water decreasing year by year, at the same time, with thedevelopment of river basin along the industrial and agricultural, amount of pollutiondischarged into was increasing year by year, plus agricultural chemical fertilizerpollution, such as the surface runoff, makes the river water environment is gettingworse.In order to ensure the safety of water supply, Handan surrounding area to ensurethe sustainable development of Yuecheng reservoir water source, the overallconsideration was upstream of the water pollution characteristics, on the basis of theYuecheng reservoir water source of water pollution control and water environmentsecurity is studied, it is very necessary.Vulnerability of water resources is an important standard of measurement of waterresources security, the research on the universal attention by scholars both at home andabroad, water resource vulnerability research can predict the future water securitychange trend, also can seek the key elements of water security, so the water resourcevulnerability research has very important significance.In this paper, the vulnerability of Yuecheng reservoir water source are studied,according to the Yuecheng reservoir water resources present situation, using the analytichierarchy process (AHP) method is used to build the Yuecheng reservoir water sourcevulnerability evaluation system, established the evaluation index system of waterresource vulnerability and the water resource vulnerability evaluation threshold, thevulnerability of water quality and water the fragility of the two aspects analyzes theirrigation area, the vulnerability of natural, human vulnerability and carryingvulnerability and other sensitive indicators, through the research, efforts to build thenorth river water and drinking water safety of technical theory system, in order to guarantee the sustainable development of Yuecheng reservoir water source safety goals.
