Outline
In order to evaluate the matching degree between water conservancy project for tobacco and tobacco drought in Guizhou Province, the daily rainfall data from 17 meteorological stations, tobacco production and water supply data of water conservancy project for tobacco during 2006-2017 was used to construct a matching degree evaluation model, and grade standard of matching degree was proposed. The results show that the water conservancy project for tobacco alleviated tobacco drought to a certain extent. However, the matching relationship between water conservancy project for tobacco and tobacco drought still needs to be improved. The matching degrees of Qianxinan, Qiannan, Anshun, Liupanshui, and Guiyang were 55.4%, 52.1%, 46.2%, 45.9%, 44.7%, and 34.4%, respectively, which were in the fourth grade with a poor matching degree. The matching degrees of Bijie, Qiandongnan, Tongren, and Zunyi were 31.7%, 28.6%, and 26.8%, respectively, which were in the fifth grade with a worse matching degree. In different growth stages, water shortage in root extension period mainly occurred in 90% and 95% effective rainfall frequency, and water shortage in prosperous and mature periods mainly occurred in each effective rainfall frequency. Additionally, the lowest matching degree occurred at the mature period. It is suggested that in the future, the layout of the water conservancy project for tobacco should focus on strengthening the construction in Zunyi, Tongren and Qiandongnan, and improve the rationality of the layout of water conservancy project for tobacco, as well as enhance the guarantee ability of drought resistance of tobacco.
