摘　　要：一年两熟设施葡萄栽培系统的能耗研究具有很强的典型性和现实意义,但传统的能耗分析具有人工计算繁琐、易出错、工作效率低等缺陷。为了解决以上问题,本研究通过分析一年两熟设施葡萄的生产流程和系统特点,建立了其能源投入产出指标,构建了DEA-BCC模型和Malmquist指数法相结合的能源效率评估模型。模型首先基于投入主导型的DEA-BCC模型测算出一年两熟设施葡萄园的技术效率、纯技术效率和规模效率这3个关键能源效率参数;然后,通过引入Malmquist函数,将生产效率变动分解为技术效率变动指数、技术进步指数和规模效率变动指数,探索能源效率增长的动力,以此对设施葡萄能源效率进行全面评估。最后基于Java EE平台下的MVC模式的B/S结构,结合Matlab Builder JA功能开发了面向一年两熟设施葡萄的能源消耗评估系统。应用测试表明,系统各功能正常运行,显著提高了能耗研究的计算效率和准确性,为一年两熟栽培模式能耗问题研究提供了可靠的数据处理支撑。The energy survey of two-harvests-a-year protected viticulture has a strong and typical significance,but traditional energy consumption analysis has some drawbacks: complicated artificial calculation,long period and low data quality.Aiming at solving above problems,an energy consumption evaluation system for two-harvests-a-year protected viticulture was developed based on MVC(mode,view,and controller) framework,B/S(browser/server) structure and Matlab Builder JA function.Firstly,a complex analysis of production process of two-harvest-a-year protected viticulture was conducted,an energy input and output system was established,and an energy efficiency evaluation model combined with DEA-BCC model and Malmquist index method was proposed.The model based on the input-oriented DEA-BCC model,through the three parameters: technical efficiency,pure technical efficiency and scale efficiency,to evaluate energy efficiency.At the same time,obtaining technical efficiency change,technical progress and scale efficiency change by Malmquist index decomposition,and conduct a comprehensive assessment of energy efficiency through the above two aspects.Then,the data from Guangxi province was chosen to test the system.Results showed that the system improved the computational efficiency,and can meet the needs of different users,as well as provided reliable data processing support for the study of energy consumption in two-harvests-a-year protected viticulture.
