摘　　要：为了探明红壤丘岗地区优化的种养结合模式在能值流动方面的特征及优势,通过采集种养系统各环节数据,采用能值分析理论和方法,研究了红壤低丘岗地区优化种养结合模式的能值投入和产出,对该模式的资源利用率、环境压力和可持续性发展指标等进行了评估。结果表明:与传统模式相比,优化模式具有较高的能值产出率,产品具有较高的价格优势,较高的能值自给率,较低的环境负载率。通过该研究,可以得知该优化模式在研究区域内具有良好的发展潜力。In order to discuss the character and advantage of emergy flow,the emergy input and output of optimization model of farming and animal husbandry were analyzed with emergy analysis method,and its indexes of resource utilization,environmental stress and sustainable development were evaluated.Compared to the traditional agricultural model,results showed that,the optimization model had higher production efficiency,more advantageous in price-competition,more powerful self-development and lower environment pressure.So the optimization model was the more potential model for development in the region.
