ABSTRACT
For studying the soil micromorphological characteristics under different land use modes, showing the micromorphology indicating significance of land use change, this paper choose loess tableland around Xi’an as a study region. The paper studied the soil micromorphology characteristics on different land uses, found the relation of soil micromorphology and land use, and the accurate interpretation of micromorphology to land use change instructions. So, this study is of importance and relevance significance. The innovation of the thesis are as following: make out the soil micromorphology composite index and access methods, and explore human activities and natural factors effect on the soil micromorphology. And describe the specific characteristics of soil micromorphology in response to land use change.
