摘要:

运用层次分析法和隶属度函数建立了土地质量地球化学评估模型,以土地利用现状图斑为评价单元,对盘锦地区耕地土地质量进行了地球化学评估。对肥力指标和环境指标综合评价结果显示,盘锦地区耕地环境综合质量状况良好,三级质量以上耕地面积达到了88.04%,是优质的水稻产区,为科学管理土地和发展特色农业提供了可靠的地球化学数据。

Abstract:

 Land quality geochemical assessment model is built using the analytic hierarchy process and membership functions. Taking the status map spots as the evaluation unit, cultivated land quality in Panjin area is assessed on geochemistry. The results of comprehensive evaluation on the fertility indicators and environmental indicators, showed that farming environment quality of Panjin area is in good condition, and that 88.04% arable land area grading fromⅠto Ⅲ quality belongs to the rice growing regions. The assessment provides a reliable geochemical data for the scientific management of land and the development of characteristic agriculture.

Key words: land quality geochemical assessment, Panjin city, analytic hierarchy process
