Through assessment, it can be concluded that the water quality in Shuimo river valley of Urumqi was worse; the water quality did not improve in last three years, and this trend was not stable either in space or in time; the water quality was best in low water period but it's worse in flush water period and slack water period; in space the water quality in Tangcichangquan section was best , it's the second place in Qifangqiao section and Lianfengqiao section while it's worst in Miquanqiao section. According to the analysis, the trend of the water quality change of Shuimo river valley of the major pollutants, the method of Spearman was used in 1996 to 2002. It concluded, the pollutants did not have the remarkable trend of change in Tangcichangquan section,but BOD5 had very prominent raising trend in Qifangqiao section, so did BOD5, petroleum, and ammoniac nitrogen in Lianfengqiao, DO in Miquanqiao section in seven years.

With the aggravation of organic pollution of the drinking water source and the improvement of the water-quality standards, the conventional treatment craft of drinking water used in most of water plants in China can't remove the organic pollutant effectively to satisfy people's demand in the water quality. Consequently, permanganate preoxidation technic and mineral materials are combined with coagulation to removing the organic pollutant of drinking water further, so that to solve the increasing contradiction between the aggravation of organic pollution of the drinking water source and the striction of the water-quality standards.

Three main methods with lacustrine carbonates have been used to reconstruct the lake water palaeo-temperature at present. First, the technique of isotopic geological thermometer, since being put forward to reconstruct sea-water paleo-temperature, was subsequently introduced into lacustrine carbonate sediments for constructing lake-water based upon the function relationship between lake-water temperature and the oxygen isotopic compositions of lacustrine carbonate and lake-water. Second, paleo-temperature of the lake-water can be reconstructed by determining Mg/Ca values of the lacustrine ostracode shells. And third, paleo-temperature of the lake-water can be reconstructed based upon the statistic model between the oxygen isotopic composition of lacustrine carbonate and the Lake-water temperature by testing the modem hydrogeological parameters and some relevant isotopic data of the lake basin.
