| 中文摘要: |
| 基于《土地质量地球化学评价规范 DZ/T 0295-2016》，利用遥感影像划分出的评价单元作为土地质量地球化学等级划分的最小单元，对西安市西咸新区窑店镇进行土地质量地球化学评价。数据显示：N总体处于缺乏状态，P、K处于中等至丰富状态。进而得到土壤质量综合评价：一等（优质）土壤面积占28.9%，二等（良好）土壤面积占38%，三等（中等）土壤面积占29.3%。分析表明，工作区土壤以优质和良好为主，有利于当地农作物生长。 |
| 英文摘要: |
| According to Code for geochemical evaluation of land quality DZ/T 0295-2016, the authors used the “Data Management and Maintenance (Application) Subsystem for Geochemical Survey and Evaluation of Soil Quality” to carry out geochemical evaluation of soil quality in Yaodian Town, Xi’an—Xianyang District, Xi'an City.The data shows that nitrogen (N) is generally in a state of deficiency, phosphorus (P) and potassium (K) in a medium to rich state.And the result of comprehensive evaluation of soil quality suggests that the first class (high-grade quality) soil area is 28.9%, the second class (good-grade) 38% and the third class (Medium grade) 29.3%. The Medium- to high -grade quality soil area accounts for 96. 2% of the total area.The analysis indicates that the soil in this area is mainly of high-grade and good-grade,which is benefit for the local crops growth. |
