Abstract:
      We filtrate forecast factors of spring crop yield in Yunnan Province using grey relational analysis and correlation analysis.The filtrated factors are used for yield forecast of 2004. Through comparative analysis we can educe conclusion: using the method of grey relational analysis,the meteorological factors can incarnate biological meaning more profitably;we can find out major factors in a system,eliminate minor factors,and grasp the principal contradiction to decrease computational complexity.
