摘要
为综合评价农业安全施肥状况,选取9个评价指标,按照5级评价标准,利用层次分析法确定各指标权重,构建农业安全施肥模糊层次综合评价模型.结果表明,研究区农业安全施肥等级从2006到2011年逐年好转,预测到2015和2020年将达到较安全状态.评价结果符合区域实际情况.
In order to evaluate the agricultural fertilizing-security, 9 indicators are selected, five- grade assessment standard is adopted, and index weights are established by analytical hierarchy process to build up an agricultural fertilizing-security evaluation model. By taking Pingchang county in northeastern Sichuan province as an example, the evaluation results show that the status of farmland health was improved from 2006 to 2011 in the study area and that the status will be better in the period from 2015 to 2020. The comparison shows that the evaluation results using this model are in agreement with the actual situation in the study area.
