摘　　要：土壤是连续分布在地球陆地表面的自然客体,其发生发展与景观密不可分.在野外调查的基础上,对辽宁沈阳样区100个土壤剖面形态特征、颗粒组成、化学特征等进行对比研究,按照《中国土壤系统分类(修订三稿)》的标准,共划分出淋溶土、雏形土与新成土3个土纲和续分的5个亚纲、7个土类、9个亚类、9个土族、14个土系.土壤性质和类型与景观特征有很好的对应关系,土壤性质是地形部位、母质基础、水分状况等景观要素的综合体现,也是长期气候等环境变化与人为活动影响的综合结果.Soil is a natural object distributed in succession on the earth surface, and its genesis and development has a close connection with landscape. Based on the field survey and the comparative analysis of soil profile characteristics, particle composition, and some chemical characteristics in Shenyang area, the soils in this area were classified into three orders （luvisols, cambisols and entisols）, five suborders, seven groups, nine subgroups, nine families, and fourteen series, according to the ＂Chinese Soil Taxonomy （ revised three drafts） ＂. There existed a good corresponding relationship between soll types and their landscape characteristics. Soil property was not only a synthetic reflection of landscape elements topography, parent material, water condition and so on, but also an integral result of long-term environmental changes and anthropogenic influences.
