摘要
以鞍山南部地区农业生态地质调查为例,阐述了通过测定主要元素在土壤中的分布,综合评价农业生态地质背景,从而研究土地种植适宜性及土壤环境安全性和治理对策,进而讨论在辽宁省开展农业生态地质调查研究的主要内容及意义.此外,对特种经济作物南果梨专项调查表明,土壤中铁、锰、镁、钾、钴元素含量决定了南果梨的独特品质,以变辉长岩或片岩和花岗岩混合岩为成土母岩地区是南果梨生长的最佳区域.
Based on the agro ecological and geological investigation in the south of Anshan,Liaoning Province,this study involves the distribution of main elements in soil,evaluation of agro ecological and geological background,planting suitability of land and environmental security of soil,as well as the treatment measures of soil.The significance and content for the agro ecological and geological investigation in the province are discussed.In addition,the special investigation on Nanguo pear (famous local fruit) showed that the unique quality is controlled by such elements as Fe,Mn,Mg, K and Co in soil.The soil weathered from meta gabbro or the mixture of schist and granite is the best for growth of Nanguo pear.
