Abstract: Mountain spot is the important resource carrier of tourism development in China.Due to unique landforms,difficult projective water supply and increasing beds and tourists,the contradiction between water supply and demand is very obvious,which is one of the key factors restricting tourism sustainable development.The representation is Huangshan Mountain.By the method of typical years analysis,this paper lucubrates the contradictions between water supply and demand of each month in subareas of Huangshan scenic spots,and concludes:(1)Generally,water supply is not enough in Huangshan scenic spots.The situation of water scarcity is obvious.Furthermore,the contradictions exist in time,space,plentiful and scarce rainfall periods,etc.(2)The paper forecasts mid-and long-term water supply and demand,and builds dynamic control model of water supply and demand.If typical scarce year is encountered in mid-and long-term periods,first,we should maintain water supply in high mountain,and then start projects to regulate water properly and timely.The important way to improve water supply is to regulate water by means of reservoirs or diversion and withdrawl projects in Huangshan scenic spots.(3)By exerting subjective motility and firstly regulating reservoirs in subareas,the present problem of water supply can be solved.Then,by pumping water to the mountain from Wuliqiao reservoir,the mid-term problem can be solved.By building Diaoqiao reservoir and connecting all water supply systems,the long-term water supply and demand can be balanced.(4)In future,environmental protection will become one of the main methods to solve the contradiction of water demand and supply,such as reducing standards of water demand,improving level of wastewater disposing,adopting wastewater reuse technique and introducing efficient water equipment and so on.
