摘要：This article offers an overview of crop production in Wengyuan County: the growing area of rice is the biggest followed by sugarcane and the growing area of mulberry, Sanhua plum and Jiuxian peach is small; the annual output of sugarcane is the biggest followed by rice, the annual output of mulberry ranks N0.3, and the output of Sanhua plum and Jiuxian peach is the lowest, but the annual output of them is very close. In accordance with evaluation indicator system concerning explicit dominance of production and development of crops, coupled with data analysis, we determine the explicit dominance of the main crops in Wengyuan County. The results show that the normalized explicit dominance of rice, sugarcane, mulberry, Sanhua plum and Jiuxian peach in Wengyuan County is 0.23, 0.94, 0.33, 0.22 and 0.46, respectively; in Wengyuan County, the sugarcane is fit to expand the scale, the mulberry and Jiuxian peach are relatively fit to expand the scale, and the rice and Sanhua plum are not fit to expand the scale.
