摘要
对铁岭市耕地、林地及自然保护区三种类型土壤进行采样和化验分析,结果表明:铁岭市全市的土壤以弱酸性为主,营养成分含量在2.660%以下,颗粒组成大部分以砂粒为主,无机污染物和有机污染物含量仅一个点位超标。用土壤综合污染指数法评价出大部分区域土壤为安全等级,仅少部分区域土壤为警戒限等级。
The results of sample and laboratory analysis on three soil type of cultivated land, woodland and nature reserve showed that： The soil of Tieling city is mainly weak acid, nutrient content under 2.660%, sand composed most of the soil particles, the content of inorganic and or- ganic pollutants exceed the standard at only one monitoring point.
