广西粮食产量变化的小波分析

Wavelet Analysis on Food Yield Change in Guangxi

采用Complex Gaussian小波变换分析方法，对1949～2008年广西粮食产量变化进行了多时间尺度分析，并预测了广西粮食产量变化趋势。提出了稳定粮食播种面积、加快农业科技创新、优化粮食结构和完善促进粮食生产政策等对策建议，以期能保障广西粮食安全。

The present study was conducted to the muh-time scale analysis of food yield change in Guangxi and its trend forecast using Complex Gaussian wavelet transformation method. The food yield of 1949 -2008 in Guangxi was used as data sample. Therefore, the stable planting area of food crops, accelerating the scientfic and technological innovation, optimizing the planting structure of food crops, and perfect the production policy of food, etc. , should be strengthened to ensure the safety of food production in Guangxi.
