本研究以宁夏上黄试区为例,根据历史资料、PRA调查及GIS工具分析了该试区耕地变化及农户经济行为变化。结果表明,耕地变化对农户经济行为的影响主要表现为农业系统内及农业系统外部经济活动的变化,农业系统内部主要变化表现为耕地种植结构变化及利用形式的变化,农业系统外农户经济活动的变化主要表现为农业系统外收入不断增加和农户外出劳务人数增加。

Taking Shanghuang experimental area of Ningxia as a case study, changes of cultivated land and farm household economic behavior were analyzed using historical data, PRA investigation methods and GIS. Results show that cultivated land changes affect farm household economic behavior both within and outside the agricultural system. Planting structures and utilization forms of crop land are the most obvious changes within the agricultural system, whereas increased income and export labors of farm household economic behavior constitute the outside changes.
