摘要
种植业结构调整是保障粮食安全的重要措施。针对种植结构调整中数据呈现出的复杂性特征,通过采用投影寻踪技术分析处理其复杂系统的高维数据,能够克服传统种植结构调整中目标单一、指标选取简单等弊端。首次将投影寻踪技术应用到种植结构调整中,建立优化配置模型,通过分析齐齐哈尔地区的数据,得出当地种植结构调整后2010年、2030年综合效益值分别增加了13%和28%,证明了将投影寻踪技术应用于种植结构调整是合理可行的,拓宽了投影寻踪应用的新思路,为种植结构研究以及农业水资源的合理利用提供理论依据。
The plant structure adjustment is a key measure to safeguard food security. Due to the complexity characteristics of data in the plant structure adjustment, projection pursuit technology （PPT for short） is adopted to analyze high-dimension data of complex system and can overcome some disadvantages of traditional plant structure adjustment such as single goal and simple index selection. Optimal allocation model based on PPT is firstly established. According to the analysis data of Qiqihaer area, the value of comprehensive benefits of the year 2010 and the year 2030 are obtained, which will respectively increase by 13% and 28G. It proves that it is feasible to adopt PPT in plant structure adjustment. The new thinking on application of PPT is expanded. Therefore, the results can provide theoretical basis for plant structure research and reasonable utilization of agriculture water resources.
