| 摘 要： | 做好土地资源数量管控,加强耕地质量管理和生态管护是当前的一项非常重要的工作。选择吉林省大安市东南区域为研究对象,进行土地质量地球化学评估,并融合污染元素进行农用地分等研究。结果表明研究区内评定为三等及以上的土壤占全区总面积的72.61%,研究区土地质量总体较好,优质和优良土地分布面积较大,主要为黑钙土,差等的土地主要为盐碱土或盐化草甸土。尝试性地将农用地分等成果中的产能评价和土地质量地球化学评估中的元素含量评价结合,开展了绿色产能评价。 |
| 关 键 词： | 农用地分等 土地质量地球化学评估 绿色产能评价 吉林省大安市 |

| Abstract: | Controlling the land resources quantity,strengthening the farmland quality management and the mana-gement of ecological protection are very important works at present.This article takes the southeast area of Da'an City in Jilin Province for example,based on the study of land quality geochemical evaluation results and farmland classification with harmful elements integrated,to assess the level of land quality grade.The results indicate that 72.61 percent of the study area is assessed above third-class.Land quality is generally good in the study area,the area of excellent and good land is relatively large,which were mainly chernozem,and the poor land is mainly saline-alkali soil or salinized meadow soil.By trying to combine the productivity evaluation in the agricultural land classification results and the element contents in the geochemical assessment of land quality,the green productivity evaluation is formed. |
| Keywords: | agricultural land classification geochemical assessment of land quality green productivity evaluation Da'an City in Jilin Province |
