摘要
程海是一个微碱性的闭口湖，ｐＨ９．１，ＤＯ９．０１ｍｇ／Ｌ，总硬度１７．１０德国度，总碱度３０．４１德国度。离子总量１０３１．７４ｍｇ／Ｌ，其中Ｎａ＋１９０．５８ｍｇ／Ｌ，Ｍｇ２＋６８．３５ｍｇ／Ｌ，ＨＣＯ３－６０５．８１ｍｇ／Ｌ，ＣＯ３２－１１７．８９ｍｇ／Ｌ，ＮＨ４＋、ＮＯ３－、ＮＯ２－、Ｆｅ２＋和Ｆｅ３＋常检不出。终年无水化学分层现象１９９２年８月，出现“翻白水”现象，透明度从２．５ｍ突然降至０．７５ｍ。程海湖水属Ｃ型，为微咸水湖。水位年平均下降０．２２５ｍ。程海将继续向咸水湖方向演化。
Chenghai lake is a alkalescence lake, has not outlet. pH is 9.1, total hardness is 17.10 Germanic degrees, total basicity is 30.41 Germanic degrees. The average annual ion contents is 1031.74 mg / litre, amoung which Na+ is 190.58 mg / litre, Mg2+is 68.35 mg / litre, HCO3-is 605.81mg / litre, being tested has not frequeatly. There are not dividing levels of hydrochemistry throughout the year. Chenghai lake emerged phenomenon of overturing white water in August, 1992, the transparency reduces suddenly from 2.5m to 0.75m. The water of Chenghai lake belongs to C, it is a slight saltwater lake. The water level has been falling by 0.225m / year. Chenghai lake will continuces to evolve to saltwatcr lake.
