Abstract:
Considering the disadvantages of stitistical methods,the degree of grey incidence is adopted in the suitability analysis of tobacco planting.The basic data is collected from 125 meteorological observation stations from 1971 to 2000.The IDS(Inverse Distance Spuared) method is used to infer the climatic information at the county/town level.The areas that are suitable for planting tobacco at the county/town level are given.Mile County is considered as the optimum place for growing tobacco,and its ecological condition was used as the bases for suitability analysis.The application results show that using the degree of grey incidence in the suitability analysis of tobacco planting is simple,practical,and reliable.
