摘要
土壤质量评价是土壤学研究的重要内容,本文综述了国外主要土壤质量评价工具的基本结构、优缺点以及应用现状,旨在为我国农业土壤质量评价提供支持。结果表明土壤质量评价工具从简单的土壤质量卡到与生态模型结合的复杂评价工具在适应性、敏感性以及准确性上都存在明显的差异,土壤评价目的不同应选择合理的评价工具,其中土壤质量卡和土壤质量检测盒在生产中应用较广泛,而土壤状况指数和土壤管理评价工具在研究中应用较多。土壤质量评价工具应用研究中评价指标的筛选与量化是重点和难点,其中土壤物理和化学指标应用较多,而对管理措施反应敏感的土壤生物学指标(如土壤微生物和酶活性)的量化研究较少。针对土壤质量评价(工具)的复杂性(适应性),通过结合土壤功能传输方程和农业系统模型扩展土壤质量最小数据集是改善土壤质量评价的重要途径。
Soil quality assessment is an important issue in soil science. To promote the soil quality assessment research in China, this paper reviews the advances in agricultural soil quality assessment tools and their applications in soil management. The agricultural soil quality assessment tools, from the simple ones as soil quality cards to the complex ones as soil assessment management framework, vary greatly in their sensitivities of managements, accuracies and flexibility in applications. Therefore, the agricultural soil quality assessment tools should be chosen for the specific soil quality assessment objectives. Among these tools, the soil quality cards and soil healthy assessment tool are commonly used in field management practices, while soil condition index and soil assessment management framework are widely used for scientific researches. Selecting and quantifying soil quality indexes are the key issues in the specific soil quality assessment, where soil physical and chemical soil quality indexes are widely used, but the biological indicators, such as soil enzyme and microbes, are rarely applied. Using agricultural system models and pedotransfer functions to extend the minimum data sets is a key way for soil quality assessment.
