在我国华中华南矿山地区附近常分布有一种特殊的水稻土。这些土壤的剖面上部可见有由于大量某种物质的聚集而形成的特殊层次,它们是在矿场采矿过程中经常流出含有大量“特殊”物质的污水侵入附近正常水稻土后,土壤剖面形态和内在性质发生显著变化的矿害性水稻土——矿毒田。对水稻等作物有不同程度的毒害影响,造成生长不良和产量降低。矿毒田的类型与矿区的矿床种类有关,例如在煤矿、黄铁矿和天然硫矿、锰矿等附近便往往分布有相应的炭浆田、硫磺田、锰毒田等水稻土。关于矿毒田的调查研究除日本的细田、出口、前田、斋藤诸氏曾对铜、砷、锰等矿毒田进行了一些研究外,在我国土壤普查以前是被忽视的, There is often a special type of paddy soil near the southern China’s mines in central China. The upper section of these soils can be seen as a special layer formed by the accumulation of a large number of substances, which is the result of frequent outflow of sewage containing a large amount of “special” substances into nearby normal paddy soils during the mining process. Mineral nature of significant changes in the mineral paddy soil - mine fields. Rice and other crops have varying degrees of toxic effects, resulting in poor growth and reduced production. The type of ore field is related to the deposit type in the mining area. For example, paddy field, sulfur field and manganese field are often distributed in the vicinity of coal mines, pyrite and natural sulfur mines and manganese mines. Except for Japan’s Matsuda, Matsuda, Maeda, and Saito Fujitsu, which conducted some research on mineral fields such as copper, arsenic and manganese, they were neglected before China’s soil census.
