标准样地在农用地分等成果汇总中的应用设想

Research on Standard Plot and its Application in Integration of Agricultural Land Classification in China

研究目的:探讨标准样地在农用地分等成果汇总中的应用。研究方法:比较研究与系统分析法。研究结果:(1)农用地分等结果的区域可比性及其全国汇总,直接影响农用地分等的科学性,对全国农用地分等工作的顺利实施至关重要。(2)分析了标准样地的内涵与类型、设立原则与意义。(3)提出标准样地土地质量评价指标体系,以构建全国标准样地类比体系。(4)对标准样地的设立与管理提出相关措施建议。研究结论:建立标准样地土地质量评价指标体系,构建全国标准样地类比体系,根据各指标区标准样地农用地分等指数之间的等比关系,进行全国农用地分等结果的统一调整、汇总,是现实可行的。

The paper tries to study the application of standard plot in integration of agricultural land classification. Method of systematic analysis was employed. The results show that regional comparability and national integration are vital to the implementation and achievement of scientific output of agricultural land classification in China. The meaning, types, principles and significance of standard plot were analyzed. Indicators for evaluating land quality of standard plot were proposed in order to construct national analogy system of standard plot. Finally, suggestions were made on the establishment and management of standard plot. In conclusion, it is realistic and feasible to set up indicator system for evaluating land quality of standard plot, to construct national analogy system, and to apply them to integration of national agricultural land classification according to relations between indexes for agricultural land classification of standard plot.
