为了解湖南省农业环境有效硫状况，１９９７～１９９８年对全省各地、州、市耕地土壤有效硫及主要河流水中硫含量进行取样测定，并对有关大气及降水中硫的资料进行收集整理．结果表明，耕地土壤有效硫含量在６．６～２６５．１ｍｇ／ｋｇ之间，平均为（３６．８±３．１）ｍｇ／ｋｇ，其中低于１６ｍｇ／ｋｇ的土样占２０．９％．土壤有效硫含量以湘西和湘北较高，湘东和湘南较低．８种成土母质发育的土壤有效硫含量从高到低依次为石灰岩、第四纪红土、砂岩、花岗岩、河流冲积物、湖积物、板页岩、紫色砂页岩．大气中ＳＯ２的含量以吉首最高，株州及郴州最低，平均含量为０．０９３ｍｇ／ｍ３．降水中硫的含量，城市平均为３．７４ｍｇ／Ｌ，郊区为２．７０ｍｇ／Ｌ，农村为１．７８ｍｇ／Ｌ．湖南省四大河流水中硫的含量（除湘江的长沙段外）为０．６７～４．４５ｍｇ／Ｌ，平均为２．４８ｍｇ／Ｌ．
In order to understand the available sulfur status of agricultural environment in Hunan Province, from 1997 to 1998, the sulfur content of soil available sulfur and the main river water of all the provinces, prefectures and cities in the province were sampled and analyzed, and the data about atmospheric and precipitation sulfur were collected and sorted. The results showed that available soil sulfur content was between 6.6-265.1 mg / kg with an average of (36.8 ± 3.1) mg / kg, of which soil samples less than 16 mg / kg accounted for 20.9% . Soil available sulfur content in western Hunan and northern Hunan higher, lower in eastern Hunan and southern Hunan. The effective soil sulfur content of the eight soil-parent materials developed from limestone to quaternary laterite, sandstone, granite, river alluvial sediments, lake sediments, shale and purple sandstone shale. The content of SO2 in the atmosphere was the highest in Jishou and the lowest in Zhuzhou and Chenzhou with an average content of 0.093mg / m3. Precipitation sulfur content, the city average of 3.74mg / L, the suburbs of 2.70mg / L, rural 1.78mg / L. The contents of sulfur in water of the four major rivers in Hunan Province (except Changsha section of Xiangjiang River) were 0.67 ~ 4.45mg / L with an average of 2.48mg / L.
