基于生态足迹分析的山区农产品结构优化探讨——以大别山区岳西县为例

Study on the Optimization of Agriculture Structure in Mountain Area Based on the Ecological Footprint——Take Yuexi County as An Example

生态足迹分析是一种定量评估区域可持续发展状态的有效方法。文章以生态足迹理论为基础,建立以经济生态综合效益最大化为原则的农产品生产种植结构优化模型,提出通过计算比较主要农产品的产值足迹的方法来优化山区农业结构;以大别山区岳西县2002年统计数据为依据,对岳西县的主要农产品进行计算分析。结果表明,茶叶、水果、禽肉与蔬菜的产值足迹是最低的,其经济生态效益最高,而水产品、油料、羊肉与玉米的产值足迹是最高的,其经济生态效益最低。文章对山区农产品结构优化的探讨可以为山区农业实现可持续发展提供切实可行的指导,同时也为山区树立科学发展观提供借鉴。

The ecological footprint theory put forward and developed by M. Wackernagel and his advisor W.E. Rees, is the succinct and effective way to measure the human impact on the nature resources and judge whether the human activities stay within its carrying capacity. This paper applies this method to explore the effective way to optimize the agriculture structure in mountain area. Accordingly, the article put forward the concept of ecological footprint per value according to main biotic products. By comparing efv, we can optimize the structure of agriculture products and realize the maximize economic ecology benefits in mountain area. Taking Yuexi County in Anhui province as an example, based on the statistics data of 2002 in Yuexi, the main agricultural products are computed by comparing efv , the result shows that the efv of tea, fruit, fowl and vegetable is lowest, accordingly its economic ecology benefits are highest. And the efv of aquatic product, oil plants, mutton and corn is highest, so its economic ecology benefits are lowest. This article provides a feasible way to instruct the sustainable development in mountain area, and it also conduces to build up the scientific development viewpoint in the mountain area.
