基于粮食经济获取能力的耕地压力指数模型

The Model of Cultivated Land Press Index on the Capability of Grain Economics Acquisition

现有耕地压力指数模型带有明显计划经济色彩,在模型构建思路和粮食自给率计算方面存在着明显的缺陷。文章在提出粮食经济获取能力概念的基础上,构建了基于粮食经济获取能力的耕地压力指数模型。研究结论表明基于粮食经济获取能力的耕地压力指数模型可以克服现有耕地压力指数模型的缺陷,提高耕地压力指数测算的科学性和可操作性。

The current model has obvious features of command economy. At the same time, the current model has obvious faults on the framework of model building and the computation on self-sufficiency rate of grain. The paper builds cultivated land press index model based on the capability of grain economics acquisition. It is concluded that the model based on the capability of graineconomics acquisition could overcome the faults of current model and increase the scientificity and operability of cultivated land index.
