【摘要】：土系是土壤系统分类的最基层单元,我国现有土系约3 000个,距约3万个的估计总量还有巨大差距,因此土系建设在未来相当长时间内仍将是我国土壤系统分类研究和土系建设的一个重点。土系描述是土系建设最为重要的一环,是土系所有信息的直观具体展现,为确保土系描述的质量,国家科技基础性工作专项"我国土系调查与《中国土系志》编制(2008FY110600)"初步制订了土系描述标准,但其在描述规范上还存在一些问题有待明确和解决。为此,本文基于土系描述标准的介绍,剖析我国土系描述中存在的主要问题和产生原因,并提出相应对策,旨在进一步完善土系描述标准的科学性、规范性、全面性和系统性,提高我国土系描述的质量。
[Abstract]:Soil series is the most basic unit of soil systematic classification. There are about 3000 soil systems in China, which is still far from the estimated total amount of about 30,000. Therefore, the construction of soil series will still be a key point in the classification of soil system and the construction of soil system in China for a long time in the future, and the description of soil series is the most important part of the construction of soil series. It is the direct and concrete display of all the information of soil series to ensure the quality of the description of soil series. The national science and technology foundational work special item "the investigation of China's soil series and compilation of China's soil series records" has preliminarily formulated the standard of soil series description. However, there are still some problems to be solved in the specification. Therefore, based on the introduction of soil series description standards, this paper analyzes the main problems and causes in the description of soil series in China, and puts forward the corresponding countermeasures. The purpose of this paper is to improve the scientific, normative, comprehensive and systematic standard of soil series description, and to improve the quality of soil series description in China.
