| 摘 要： | 浙江省龙游县是依据"浙江省典型市县级土地质量地球化学评估"项目任务及要求选择的评估区。基于总结、示范的需要,重点介绍了土地质量地球化学方法技术、成果整合及应用情况。土地质量地球化学评估将土地质量划为5个等级,根据室内、野外的验证情况,调整评估指标、指标权重及评估单元,进行重新评估,以得到更为科学合理的评估结果。为了土地管理部门更方便地利用评估成果,将农用地分等与土地质量地球化学评估成果用叠加法进行整合。整合的结果一方面反映了不同评价方法评价结果的一致性,另一方面也揭示了相同农用地等存在的差异性。龙游县国土部门充分利用了本次土地质量评估成果,对城镇周边已规划的建设用地进行了重新布局。调整后,集中连片的优质耕地得到了保护,建设用地的总量也得到了保证。

| Abstract: | According to mission requirements, the demonstration project of “land quality geochemistry assessment on county-level and city-level of Zhejiang province” is carried out in Longyou county, Zhejiang Province. Based on the needs of summary and demonstration, the methods, techniques, application, and achievements of land quality geochemical assessment in Longyou county are emphatically introduced. In order to get more scientific and reasonable assessment result, the geochemical assessment of land quality in Longyou area is taken according to the indoor and outdoor verification, adjusted index of assessment, index weight and assessment unit, the land is divided into five levels. In order to make use of the assessment results more convenient, the geochemical classification and gradation of farmland quality are integrated with superposition method, which shows a consistent result of different assessment methods, and reflects the differences of the same gradation. The land and resource department re-programs construction land around Longyou county by making use of the achievements in land quality geochemical assessment. After adjustment, the concentrated high quality farmland has been protected, and the construction land demand has been ensured. |
