| 摘 要： | 土壤肥力是土壤的基本属性和质的特征,其评价指标体系的建立是实现自然资源综合观测和统一管理的重要支撑,然而,目前仍然没有建立一个统一的标准和指标体系。本文基于文献计量的方法,对CNKI库中相关文献进行统计分析,总结了国内学者对土壤肥力质量评价所选用的主要指标,并分别从土壤化学、土壤物理和土壤生物学3个不同性质方面进行探讨。结果表明,有机质、全氮和速效钾等是土壤化学性状的重要指标,容重、土壤含水率和质地等是土壤物理性状的重要指标,脲酶、转化酶和代谢熵等是土壤生物学性状的重要指标。在此基础上,以全国自然资源综合观测和统一管理的需求为导向,遵循综合性、稳定性、独立性和获取性的指标选用原则,提出了土壤肥力评价指标体系的初步构建方案,旨在为开展土壤资源长期定位观测和质量评价提供科学依据。 |

| Abstract: | Soil fertility is the basic property and qualitative characteristic of soil, and the establishment of its assessment indicators system is an important support for the comprehensive observation and unified management of natural resources. Based on the bibliometric method, this paper made a statistical analysis of the relevant literature in the CNKI database, summarized the main indicators used by domestic scholars in assessing soil fertility, and discussed three different properties of soil chemistry, soil physics, and soil biology. The results showed that organic matter, total nitrogen and available kalium were important indicators of soil chemical properties, bulk density, soil moisture content and texture were important indicators of soil physical properties, urease, invertase and metabolic quotient were important indicators of soil biological properties. On this basis, guided by the requirements of natural resources comprehensive observation in China, and following the principles of comprehensive, stability, independence and accessibility, the preliminary construction scheme of the soil fertility quality assessment indicators system was proposed, aiming at providing scientific basis for long-term soil resource positioning observation and quality evaluation. |
| Keywords: | comprehensive observation of natural resources soil quality soil fertility assessment indicators soil chemistry soil physics soil biology |
