doi:10.7523/j.issn.2095-6134.2014.01.013

Abstract

Abstract:

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.

Key words: hierarchical fuzzy recognition model, pressure-state-response framework, agricultural fertilizing-security, evaluation
