摘  要：
针对当前县际耕地地力评价结果不能直接对比汇总、市域评价不能有效利用县级评价成果的难题,以河南省漯河市为例,对县域-市域耕地地力评价结果的尺度转换方法进行研究。在县域耕地地力评价结果与市域耕地地力评价结果一致性分析的基础上,提出了基于概念性产量和标准样地县的县域-市域耕地地力评价结果尺度转换方法;实证研究表明现有漯河市各县(区)与市域耕地地力评价结果吻合情况存在差异,其中舞阳县一致性最好;以舞阳县为标准样地县,构建标准样地县耕地地力等级与概念性产量关系表,以此为标准,调整其它县(区)耕地地力等级,生成市域耕地地力评价结果;通过各县(区)粮食概念性产量与调整后耕地地力等级的变差分析验证调整结果的合理性,结果表明各县(区)概念性产量与调整后的地力等级均呈现显著的一致性,表明调整生成的市域评价结果符合实际,提出的尺度转换方法合理可行。

摘  要：
Because the evaluation results of cultivated land productivity of different counties were difficult to be directly compared and summarized,and cannot be utilized by cultivated land productivity evaluation at city-scale,this study took Luohe City,Henan Province,as example,to study the transformation method of cultivated land productivity evaluation between city-scale and county scale.According to consistency analysis of county-scale and city-scale cultivated land productivity evaluation results,a scale transformation method was proposed based on conceptual production and county-city transformation of cultivated land productivity evaluation results of standard sample county.The results showed that in Luohe City,there were some differences for all counties between county-scale and city-scale cultivated land productivity evaluation results,and the difference was the least for Wuyang County.We selected Wuyang County as the standard sample county,and construct the relation table between conceptual production and land productivity levels of Wuyang County.According to this relation table,we adjusted land productivity levels of other counties in Luohe City,and got new cultivated land productivity evaluation results of Luohe City.Then we examined the adjusted evaluation results by using variate difference analysis of conceptual production and adjusted evaluation results.The results showed that the conceptual production and adjusted cultivated land productivity evaluation results performed good consistency for all counties of Luohe City,indicating that the adjusted evaluation results were factual and could meet the requirement.Therefore,the scale transformation method was reasonable and feasible.
