摘要/Abstract

摘要： 农业资源的高效利用是粮食安全的关键因素,对农业资源优劣势现状的排序可以为有效地开发农业资源提供参考。本文提出了以农业资源开发潜力和利用效率为基础的农业资源开发优势度的概念和计算模型,并以甘肃省为例,分析计算了甘肃省各县市农业资源开发的优势序列。结果显示:农业资源开发优势度模型很好地拟合了甘肃省农业资源的现状和区域差异。作为农业资源综合开发优势度指标,陇南、陇东和陇中等雨养农业区以及甘南州光能资源优势区耕地资源开发优势度处于4~5级水平。河西绿洲灌溉农业区耕地生产力水平得到了很好的开发,耕地资源开发优势度处于1~2级水平,但是由于民勤、金昌两个地区生态系统的退化,耕地资源开发优势度处于3级 (中等)水平。

Abstract: High-efficient utilization of agricultural resources is a key factor for food security, and the order list of agricultural resource utilization can provide effective reference for further exploitation of agricultural resources. In this article, the author puts forward the concept and estimates model of development dominance ratio of agricultural resources on the basis of agricultural produce potential and agricultural resources utilization efficiency. Taking Gansu province as a case, the list of development dominance ratio of agricultural resource is evaluated and analyzed. The results of the study show that: the model of development dominance ratio of agricultural resource can simulate further exploitation potential and regional difference of agricultural resources in Gansu province. Farmland development dominance ratio can reflect comprehensive development dominance ratio. In the rain-fed agricultural zone, such as Longnan, Longdong and Longzhong districts, the development dominance ratio of agricultural resources is about 4 to 5 levels. The condition is the same in the plateau region of Gannan Prefecture, due to the high exploitation potential of abundant light resources. Because irrigation agriculture promotes farmland productivity, in Hexi Oasis irrigation agricultural zone, the development dominance ratio of agricultural resources is lower, being 1 to 2 levels. However, because the agro-ecosystem is degenerated, the development dominance ratio of agricultural resources in Minqin and Jinchang districts is lower than other irrigation zone, being about 3 levels.

Key words: agricultural resources, development dominance ratio, Gansu Province
