| 中文摘要: |
| 应用能值分析理论和方法,分析内蒙古武川县种植业系统环境基础和经济特征。结果表明:武川县种植业系统不可更新资源能值投入和化肥投入能值占总能值投入的84.2%,属于典型的资源消耗型种植系统。由于农产品生产成本较高,再加上对资源环境的过度利用,在同等条件下,其农产品在国内和世界市场并不具有竞争能力。改善环境投入,优化资源利用结构,才能提高种植业系统生产力。 |
| 英文摘要: |
| Using the theory and method of emergy analysis, the paper analyzes environmental basis and economic features of the farming system practiced in Wuchuan county of Inner Mongolia. The results make it clear that the emergy input of nonrenewable resources and chemical fertilizers accounts for 84.2% of the total emergy input in the farming system of Wuchuan county and thus the farming system belongs to a typical emergy-consuming farming system. Because of its high costs of agro-products as well as overuse of environmental resources, the agro-products of the farming system do not have competitive edge in domestic and international markets under the same circumstances. Thereupon, improving environmental input and optimizing emergy use structure can improve the capacity of the farming system. |
