| 摘 要： | 从农户土地利用目标变化相关理论出发， 依据在不同经济发展阶段下， 农户土地利用目 标的产量最大化、产量与利润最优化和利润最大化三个阶段的变化特征， 创建了基于农户土地利 用目标变化的“压力- 状态- 效应- 响应”逻辑框架模型； 并据不同经济发展阶段下的“压力- 状态- 效应- 响应”的变化特征， 构建了基于农户土地利用目标变化的耕地质量评价指标体系。这一评价 指标体系的建立为我国在不同经济发展阶段下， 从农户尺度上进行耕地质量保护提供政策依据。

| Abstract: | Due to huge food need, arable land quality is very important in China, and how to evaluate its quality has been studied by many researchers. However, different regions of China are at different stages of development with different land use objectives. The first is yield maximization stage, and the household land use objective is to meet family food consumption need. The second is yield and profit optimization stage, and the house land use objective is to make more profits on the basis of meeting basic family needs. The third is profit maximization stage, and profit is the only land use objective for the household. Based on the theory of different development stages and land use objectives, a “Pressure- State - Effect - Reaction”model was developed in this paper to evaluate arable land quality at household level. The Pressure indictors include land scale, land quantity, society, economy and household family. The State indictors include land use type and pattern, input intensity and land use efficiency. The Effect indictors include soil quality, productivity and soil pollution. The Reaction indicators include governmental policies and economic measures. This model can be used to evaluate arable land qualities at different development stages, and the results can help the government make suitable policies to protect arable land for sustainable development. |
