| 摘 要： | 土地质量地球化学评估与耕地质量等级调查评价,都是涉及土地资源的质量调查与评价的基础性工作。两项成果的整合研究,是当前数据共享与学科间数据交叉融合的必然趋势。笔者将两项成果有机结合,分别从数据独立性、成果实用性、科学性等角度出发,对两项成果分别采用基于两项成果数据的叠加法、综合法和基于两项调查数据的因素法进行数据整合方法探讨,并以吉林省前郭县为研究区,对整合成果的适用性及优缺点进行讨论。结果表明,不同的整合方法各有优缺点:基于两项成果数据的叠加法可以保持成果各自的独立性;基于两项成果数据的综合法易于表达,但过于强调经验;基于两项调查数据的因素法物理意义明确,但理论支撑不足。

| Abstract: | Land quality geochemical assessment and cultivated land quality evaluation constitute the basic work of the land resources quality investigation and evaluation. Integration research on the two results is an inevitable trend between the current data sharing and cross-disciplinary data integration. In this paper, from data independence, results practicability and scientificity, the two results were combined by simple superposition method, comprehensive method or factor method. With Qianguo County in Jinlin Province as a case study area, the authors investigated the advantages and disadvantage of the integration results. The results show that different integration methods had different advantages and disadvantages：the simple superposition method based on data of two results could maintain their respective independence;the comprehensive method based on the results is easy to express, but with too much emphasis placed on ex-perience;the factor method based on two survey data can clearly express the physical meaning, but with insufficient theoretical support. |
