四川盆地西部漂洗土壤区水体铁元素的分布特征
Distribution of Iron in Water in Bleached Soil Region of the West Sichuan Basin, China
摘要
Abstract
Iron is the important index of water quality monitoring. To study the iron form and content in different water body and the seasonal dynamic of groundwater in bleached soil area in the west of Sichuan Basin, surface and ground water samples from well, pool, paddy field and tea garden, and soil samples from paddy field and tea garden were collected in Mingshan County, Sichuan Province at different time, then the form and content of iron, and other basic chemical properties in water and soil were analyzed. The results showed that the content of total and ferrous iron in groundwater(0.30 mg· L-1 and 0.08 mg· L-1, respectively) was the lowest, and that in porewater from paddy field (2.92 mg· L-1 and 1.13 mg· L-1, respectively ) was the highest. The content of total and ferrous iron in porewater from paddy field was higher than that from tea garden( 1.25 mg·L-1 and 0.92 mg·L-1 from less than 3 years tea garden, 2.66 mg·L-1 and 0.65 mg·L-1 from more than 6 years tea garden).The content of total and ferrous iron in porewater was higher than that in surface water. The content of total iron varied from 0 to 0.86 mg· L-1,and the ferrous iron content varied from 0 to 0.36 mg· L-1, and seasonal dynamic of iron in groundwater in different area was different. These were related to topography position, surface runoff condition, distance to house of human and animal, soil pH, form and content of organic matter and iron in soil, type and time of land use, weather status and micro-environment of well itself.关键词
