Abstract: |
This research aims to study the influence of climate warming on climate suitability of apricot cultivation, so as to provide reference for scientific development planning of apricot in Xinjiang. Based on the data of daily mean temperature and minimum temperature from 102 meteorological stations in Xinjiang during 1961 2016, the fundamental spatial temporal change characteristic of key climatic factors affecting Apricot planting, such as ≥10℃ accumulated temperature(∑Tmen≥10℃), minimum temperature in winter (Tmin) and the days which was the last frost date earlier than the first date of daily mean temperature ≥10℃(DFTmen≥10℃ LF), were analyzed by using the statistical methods of linear regression, accumulative anomaly, T test and mixed spatial interpolation technology based on ArcGIS. The effect of above climatic factors change on Apricot planting climatic suitability, and the distributed areas of most suitable, suitable, sub suitable and unsuitable to Apricot planting were studied by combining with the climatic suitability zoning index of Apricot planting. Under the comprehensive influence of above climatic factors, the most suitable areas for Apricot planting were in the plain of Tarim basin southwestern margin, suitable areas were mainly in the midwest of the Tarim basin and Turpan basin hinterland, sub suitable areas were in middle east Tarim basin and the south of Tuha basin, most of the northern Xinjiang and Altai mountain, Tianshan mountain, Kunlun mountain were not suitable for Apricot planting. Affected by global warming, after 1997, the most suitable areas, suitable areas and sub suitable areas for Apricot planting increased in varying degrees, while the unsuitable areas decreased significantly. The climate warming tends to be beneficial to apricot planting in Xinjiang. |
