前 言 辽宁千山所处地带为鞍山工业区,提出现状的土壤镉、铅背景值的标准,对今后衡量千山土壤是否受到镉、铅的污染具有极其重要意义。本文仅就千山土壤微量元素的镉,铅背景值进行了初步探讨。 一、千山的自然概况和环境特点 千山地处辽宁鞍山市东约二十五公里,自然地理位置是北纬40°,东经123.4°,它是长白山脉南端延伸,在辽南地区形成了千山山脉。按千山自然保护区的地形可分为三条沟,即北沟,中沟,南沟;三条沟大致平行,东北西南去向。仅西沟为西北东南去向。气候为明显的季风型。地形较高,植被类型的垂直分布差异明显。在自然区划上仍属于温带半湿润地区针阔混交林——棕色森林土地带。
Preface The location of Qianshan Mountain in Liaoning is Anshan Industrial Zone. It is of great significance to propose the status quo of the background values of Cd and Pb soils in the future. It is of great significance to measure whether Qianshan soil is polluted by cadmium or lead in the future. This paper only on the Qianshan soil trace elements cadmium, lead background value were discussed. I. QIANSHAN NATURAL PROFILE AND ENVIRONMENTAL CHARACTERISTICS Qianshan is located about 25 kilometers east of Anshan City, Liaoning Province. Its natural geographical location is 40 ° N and longitude 123.4 ° East. It stretches southward of Changbai Mountain and forms Qianshan Mountains in southern Liaoning Mountains. According to the topography of Qianshan Nature Reserve can be divided into three ditch, that is, the northern ditch, in the ditch, the southern ditch; roughly parallel to the three ditch, northeast southwest. West ditch only northwest southeast. The climate is clearly monsoon type. The topography is high, and the vertical distribution of vegetation types is obviously different. In the natural division is still temperate semi-humid mixed coniferous and broad-leaved forest - brown forest land zone.
