摘要
本文对甜菜土地质量评价的目的、程序和方法作了探讨.在研究了甜菜对外界环境条件的要求和国内甜菜主产区土地自然条件的基础上提出土壤有机质等12个常规评价因素和土壤盐碱化程度等5个特殊地区评价因素;根据土地质量诸因素对甜菜生产的适宜性、限制性将评价因素划分5个等级.在评价因素的筛选和权重的计算中,概略介绍了应用计算机进行回归分析方法.
Making an approach to the evaluating aim, procedure and method of soil quality in this paper.Based on the investigation for the requirement of outside environment and the natural condition of land of main sugar beet production areas in our country and putting forward that there were 12 conventional evaluating factors (e.g. the soil organic matter and so on) aad 5 special regional evaluating factors (e.g. the soil salinity and alkalinity and so on).The evaluating factors could divided into 5 scores according to the suitability and restriction of the various factors of soil quality to sugar beet production. The method of regression analysis with the computer were introduced in the screening of evaluating factors and weighting calculation.
