耕地质量评价是我国耕地保护的重要基础工作。研究耕地综合质量评价及其成果应用，对促进我国土地资源管理向数量与质量并重、协调生态环境统一管理方式的转变，提高土地质量评价的科学性与实用性具有重要意义。以河南温县为例，选用GIS叠加分析法有效整合农用地分等与土地质量地球化学评估成果后对该区耕地进行了综合质量评价。同时结合当地名特优农产品喜嗜典型元素含量及空间分布情况，探讨了评价结果在新增建设用地布局优化中的应用方法。布局优化后的新增建设用地占地利用等12等耕地减少12．13 hm2、利用等11等耕地减少1．6 hm2，肥力中等、环境正常、地化综合质量优良的耕地减少13．73 hm2。 N元素2-4级高富集区、P元素1-3级高富集区面积减少13．73 hm2、重金属Pb元素1级高富集区面积增加13．73 hm2。整合成果丰富了耕地综合质量的内涵，促进了土地资源合理利用。
耕地質量評價是我國耕地保護的重要基礎工作。研究耕地綜閤質量評價及其成果應用，對促進我國土地資源管理嚮數量與質量併重、協調生態環境統一管理方式的轉變，提高土地質量評價的科學性與實用性具有重要意義。以河南溫縣為例，選用GIS疊加分析法有效整閤農用地分等與土地質量地毬化學評估成果後對該區耕地進行瞭綜閤質量評價。同時結閤噹地名特優農產品喜嗜典型元素含量及空間分佈情況，探討瞭評價結果在新增建設用地佈跼優化中的應用方法。佈跼優化後的新增建設用地佔地利用等12等耕地減少12．13 hm2、利用等11等耕地減少1．6 hm2，肥力中等、環境正常、地化綜閤質量優良的耕地減少13．73 hm2。 N元素2-4級高富集區、P元素1-3級高富集區麵積減少13．73 hm2、重金屬Pb元素1級高富集區麵積增加13．73 hm2。整閤成果豐富瞭耕地綜閤質量的內涵，促進瞭土地資源閤理利用。

The purpose of this paper is to explore the technical application mode of cultivated land com-prehensive quality through the case of Wen County ,Henan Province.Evaluation of comprehensive guality of cultivated land is of great significance in promoting the transformation of China ’ s administrative model into“E-qual emphasis on quantity and quality ,coherence with ecological environment” type successfully and in impro-ving the scientificity and rationality of land quality evaluation .In this study the cultivated land comprehensive quality evaluation was conducted based on the integration of land quality geochemical assessment and agricul -tural land classification in GIS ways with the typical elements .The final results of cultivated land comprehensive quality evaluation were applied into optimizing the allocation of incremental construction land .The results of op-timization were that 11 gradation area of agricultural land utilization was reducedby 1.6 hm2 and 12 gradation area of agricultural land utilization was reduced by 12.13 hm2.Meanwhile,2 gradations areas of land fertility quality ,land environmental quality ,land comprehensive geochemical quality was reduced by 13.73 hm2 .The areas of 2-4 enrichment-levels of N,P were both reduced by 13.73 hm2 ,and therefore the area of 1 enrichment lev-els of Pb was increased by 13.73 hm2 .The integration results enrich the meaning of cultivated land comprehen-sive quality ,and guide the sensible utilization of land resources .
