摘要: |
提出了模糊数学方法与半定量评价法相结合的农田土壤综合评价方法,利用ArcView GIS 3.1地理信息系统和Visual Basic软件,实现了对试验田内土壤肥力水平的综合评价,生成了土壤单项养分空间分布图和土壤综合肥力空间分布图。经对比分析,结果表明此方法的评价结果比较准确。 |

Abstract: |
A in the field comprehensive evaluation method was developed. In order to attain a better result, this method integrated fuzzy mathematics together with traditional quasi quantificational field comprehensive evaluation method. This method was realized by Visual Basic programming, and ArcView GIS 3 1 was used to generate soil fertility distribution map and the evaluation result map. After comparision study, it has been shown that this evaluation method is effective and accurate. |
