摘要
为了研究不同因子对农田土壤墒情影响的重要程度,采用AHP-模糊综合评价模型,构建了农田土壤墒情综合评价指标体系及相应的评价标准,并对川中丘陵区盐亭县不同覆盖方式下的农田土壤墒情状况进行了实证分析。研究结果表明:采用一定的覆盖方式可以提高土壤墒情状况。6种覆盖方式下的土壤墒情状况由好到差依次为:全膜覆盖>深挖+秸秆>半膜覆盖、深挖>秸秆>传统耕作。本文的研究结果能为川中丘陵区防旱抗旱提供科学参考。
In order to study the impact of different factors on the farmland soil moisture,the comprehensive evaluation model of AHP- fuzzy has been selected to construct a comprehensive evaluation index system and a corresponding evaluation criteria,and analyzed the farmland soil moisture conditions under different mulching patterns in Yanting county. The results indicated that some mulching patterns could help to improve the conditions of soil moisture. The sequence from good to bad is,completely film mulching,（ dig ＋ straw）,half film mulching ＋ dig,straw,conventional plowing. This paper could provide a scientific reference for drought control in the hilly area of central Sichuan.
