  1. In ranking the indicator system of affecting cultivated land being selected into prime farmland has been built firstly, which is composed of 18 indicators involved in quality, location, policy attribute and administrative intervention of cultivated land. then based on the character of ranking, the idea of combination decision has been brought forward, ranking cultivated land synthetically with three ranking models including a model by similarity to ideal point, fuzzy optimization model and attribute hierarchy model. in three models the weights are based on hierarchy analysis and entropy weights, considering not only subjective partiality but also the intrinsic information of decision objects, which make the ranking results more scientific, reasonable and credible

    在耕地綜合排序中首先建立了耕地入選基本農田的決策指標體系,由耕地質量狀況、區位條件、政策屬性以及行政干預4大決策因素共18個決策指標構成;然後根據排序問題的特點,提出了「組合決策法」的思路,並採用逼近於理想點的排序模型( topsis ) 、模糊優選模型( fom )和屬性層次模型( ahm )三種排序方法對耕地進行綜合排序,每種排序模型中均採用基於層次分析法和熵權系數法確定的綜合權重,既考慮決策者的主觀偏好,又充分利用決策對象的固有信息,使排序結果更為科學、合理、可靠。
