| 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. |
| Keywords: | land quality geochemical assessment Panjin city analytic hierarchy process |
