Abstract

Abstract: Based on meteorological observation data of 11 stations in Qaidam Basin from 1991 to 2018 and the developmental period data of Lycium barbarum, a climatic suitability model for the cultivation of Lycium barbarum in the Qaidam Basin was established. By calculating the climatic suitability of wolfberry in Qaidam Basin in the past 28 years, the evaluation index of climatic suitability of wolfberry was established, and the suitability of wolfberry planting area in Qaidam Basin was divided by using GIS. The results showed that the climatic suitable areas for Lycium barbarum planting in Qaidam Basin were distributed in the relatively low altitude areas, including central and southern Delingha, northwestern Dulan county, central and northern Golmud and Mangya, etc. The generally suitable areas were distributed in the northwest of Dacaidan and surrounding areas of suitable areas. The unsuitable planting areas were distributed in the north of Delingha, Tianjun, eastern Wulan and the surrounding areas at higher altitudes of the Qaidam Basin. This research results can provide scientific and technological support for the adjustment of the characteristic agricultural planting structure of Lycium barbarum in the Qaidam Basin, the rational use of climatic resources, and the improvement of the economic, social and ecological benefits of agricultural production.

Key words: Qaidam Basin, climate suitability, Lycium barbarum planting, evaluation index
