- Abstract:
- 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 28%.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.
