一、前言在低山丘陵地区,立地条件的优劣很大程度上取决于土壤条件。因此土壤调查是划分造林立地类型的基础工作。土壤类型划分与评价工作,欧美一些发达国家都很重视,并做了许多研究。我国在这方面也做了大量工作。其基本做法是:(1)采用森林土壤发生学原理分类土壤,(2)采用森林士壤属性分类方法进行土壤划分。常规的森林土壤调查野外工作量大,并要求调查员具有较高的业务水平。近二、三十年发展起来的遥感 First, the preface In the hilly areas, the advantages and disadvantages of site conditions depends largely on soil conditions. Therefore, soil survey is the basic work of dividing the type of afforestation site. Soil classification and evaluation of the work, some developed countries in Europe and the United States attach great importance and did a lot of research. My country has also done a great deal of work in this area. The basic approach is as follows: (1) The soil is classified according to the forest soil genesis principle, (2) the soil is classified by the forest taxonomy. Conventional forest soil surveys have a large field workload and require investigators to have high levels of professionalism. Nearly two or three decades of development of remote sensing
