福建省大田县地处戴云山中段西侧,县境内矿藏比较丰富。近几年来,国营、集体、个人开矿业发展很快,1985年全县开采原煤75万吨,铁矿石19.48万吨,硫铁矿6.71万吨。各类矿产开采总产值3226.88万元,占全县工业总产值40.17％。然而,有些单位在开采过程中,忽视了保持水土,造成了矿区的水土流失。据调查,全县开矿破土面积1372亩,破坏森林植被6945亩,均未进行采后的垦复和植树种草。被剥离的沙土和煤矸石又没有妥善处理随意堆放,加剧了矿区的水土流失。有的开采单位任意将矿渣尾砂倒入河道。如汤泉铁矿平均每年倾倒于河道的废弃砂土石约30万吨,不仅淤积了河床,还造成了水质污染。还因矿区附近的地貌与植被遭到破
Datian County, Fujian Province, is located on the western side of Daiyunshan, county rich mineral resources. In recent years, state-owned, collective and individual mining industry developed rapidly. In 1985, the county exploited 750,000 tons of raw coal, 194,800 tons of iron ore and 67,100 tons of pyrite. The total output value of all kinds of mineral mining 32,268,800 yuan, accounting for 40.17% of the county industrial output value. However, some units neglected to keep soil and water during the mining process, resulting in water and soil loss in the mining area. According to the survey, the county mining area of 1372 acres of ground-breaking, destruction of 6945 acres of forest vegetation, were not carried out after the reclamation and planting trees and grass. The stripped sand and gangue have not been disposed of properly and have exacerbated soil and water loss in the mining area. Some mining units arbitrarily slag tailings into the river. For example, Tangquan iron ore dumps an average of 300,000 tons of abandoned sand and stone every year in the river channel, not only silting up the riverbed, but also causing water pollution. Also due to the mining area near the landscape and vegetation have been broken
