Given the adverse effects of current water shortages,low utilization and imbalance between the supply and demand,and other status quo problems relating to social economic development,the construction industry and agriculture,a cloud model was applied to a water resource system using five sustainable water resource utilization schemes for Kiamusze,Heilongjiang Province,as an example.This research changes the qualitative description of the concept language into a quantitative analysis of an evaluation indicator.A cloud model-based analytical method for regional sustainable water resource utilization schemes was proposed,and the sustainable grades of the water resources were calculated.The research results showed that,in addition to the natural continuation of such schemes,the development trends of four new schemes achieved the sustainable utilization of water resources,and thus,the sustainable water resource utilization was optimized.However,when the open-source,throttle,comprehensive and coordination schemes were subjected to the optimum applicability analysis,based on the limiting factors in different periods,resource availability and long-term development,decision-making regarding the best solution in different periods better ensures sustainable development in Kiamusze.The research results provide a significant theoretical basis for the formulation of scientific and reasonable sustainable water resource utilization strategies in Kiamusze.

The paper analyzed the seasonal variation of the concentrations of Cr,Mn,Al,N,P,As,Ba,Ca,Cu,Fe,Mg,and K in South Lake Cyohoha water using spectroscopic technique.Water samples were taken monthly at Ngenda,Karehe and Nyamabuye stations from January 2009 to December 2010.The results showed that the concentrations of aluminum,nitrogen,potassium,arsenic,phosphorous,manganese,chromium,barium and copper were high during the raining season and low during the dry season,while calcium,iron and magnesium varied independently with seasonal change.The results of conductivity and pH also confirmed the effects of seasonal change on the quality of water in the South Lake Cyohoha since the highest value of conductivity was found during the raining season,while the smallest was observed during the dry season,for pH the highest number was noticed during the dry season and the lowest during the raining season.
