| Abstract: |
| Based on the daily meteorological data of 109 weather stations in Shanxi Province from 1981 to 2010 as well as years of potato yield and growth data in 7 traditional representative counties (District), key climatic factors affecting potato yield were selected by correlation analysis. The factors, the average minimum air temperature on tuber formation stage, accumulated precipitation on tuber formation stage and average minimum air temperature on starch, accumulation stage were determined as the climatic regionalization indexes for potato planting in Shanxi Province. Based on the GIS technology, the meteorological elements were interpolated into a fine grid of 1km×1km. The climatic regionalization map of potato planting in Shanxi Province was made according to the suitable area, sub-suitable area and unsuitable area for potato planting by using expert scoring method. The findings could objectively reflect the status of potato planting in Shanxi Province and provide scientific basis for the rational use of climate resources and the adjustment of potato planting layout under the climate change background. |
