Study On The Carrying Capacity Of Water Resources In Zhangqiu

Water resources is important natural resources in the development ofnational economy and social,one of the important factors affecting theecological environment.With the rapid development in the economic and socialprogess,the conflicts between the supply and demand of water resources havebecome more and more outstanding.The problem of water resources have becomerestraints and "bottle neck"against the sustainable development of thenational economy and socoal progress,the problems such as drought and watershortage ,floods and water logging,water enironment deterioration ,watererosion and soil loss.How to properly handle the relations between waterresources and population as well as between environment and sustainable economicdevelopment has become a focus pf social concern and a hot topic of scientificresearch..There for,it is of the significance to reseach the carrying capacityof the regional water resources,optimize the distribution of water resources.Now,well-rounded theory,concept,ways and means have not been founded.Zhangqiu lies in the Eastern China and has the typical continent climate.In the last few decades, Zhangqiu becomes short of water resources because ofthe development of economy, population and fallacious utilization of water.Basedon the status in quo and tenth-five-year plan and 2010,2015 goal,this papercalculates the maximum supporting capacity of social economy,city scale andpopulation by analyzing the current technological,economical,social andecological level.This paper conbines the routine trend forecast with the fuzzy comprehensiveestimation,and forecasts water requirement and water supply requirement in2010,2015. Based on the adjusted parameters of model,this paper confirms nineestimating factors: average water quantity, efficiency of water use,averagewater supply,water supply modulus,living water ration,etc.and estimates thewater resources carrying capacity of Zhangqiu applying the fuzzy comprehensiveestimation.Further, stratagems and measures to meet the waterused demand andthe social,economic development.Some conclusion are as follows:(1)Projectâ… : without regard to water indraught,saving,sewage reuse,the...
