| 建立科学、合理、实用的酸性农田土壤改良效果综合评价体系，为酸性农田改良效果评价工作提供依据。利用文献分析法筛选酸性农田土壤改良效果的评价指标，采用层次分析法确定指标权重，构建酸性农田土壤改良效果综合评价体系，并以云南省梁河县的酸性农田实验进行验证。本文以酸性土壤改良为关键词查阅文献，根据各指标出现频率筛选出土壤肥力、作物生长与安全和经济效益3个中间层指标，土壤有机质、土壤pH、交换性酸等24个最低层指标，确定了各指标权重系数，建立了酸性农田土壤改良效果的综合评价指标体系，利用逼近理想解排序（TOPSIS）加权法对大田实验改良效果进行排序为复合定性纤维素204（SQC204）>复合定性一纤维素201（SQC201）>复合定性铁铈纤维素（SQFC-00S） |
| 英文摘要: |
| This study aimed to establish a scientific, reasonable, and practical evaluation system for soil improvement in acidic farmland, and to provide a basis for evaluating this improvement. The relevant evaluation indexes were selected based on a literature review. The analytic hierarchy process was used to determine the index weights, and a comprehensive evaluation system was constructed to determine the soil improvement effect in acidic farmland. The results were verified through an experiment on acidic farmland in Lianghe County, Yunnan Province. Based on a keyword search in the literature, we screened for the occurrence of all indexes related to soil fertility, crop growth, and safety and economic benefits to determine the middle level indicators;soil organic matter, soil pH, exchangeable acidity, and 24 other parameters were evaluated to determine the lowest level indexes. Subsequently, the coefficient of each index weight was determined and a comprehensive evaluation index system was established to evaluate the acidic soil improvement effect. Based on the technique for order preference by similarity to an ideal solution(TOPSIS) weighting method, the improvement effect obtained in the field experiment was ranked in the order of synthesize qualitative cellulose 204(SQC204) >synthesize qualitative cellulose 201(SQC201) > synthesize qualitative Fe-Ce cellulose(SQFC-00S). The evaluation system constructed in this study can provide a reference and basis for the evaluation of the improvement effect of acidic farmland soil. |
