基于细网格的山西省马铃薯种植气候区划
Climatic regionalization for potato planting in Shanxi Province based on fine gridding

为了给山西省在气候变化背景下合理利用气候资源、调整马铃薯种植品种布局提供科学依据，利用山西省109个气象站近30 a（1981-2010年）逐日气象观测数据，结合马铃薯传统种植区7个代表性县（区）多年的产量和发育期资料，通过相关性分析筛选出影响马铃薯产量形成的关键气候因子，确定以结薯期平均最低气温、结薯期降水量、淀粉积累期平均最低气温作为山西省马铃薯种植气候区划指标。基于GIS技术将所有气候要素插值为1 km×1 km的细网格, 采用专家打分法按适宜、次适宜和不适宜3个等级制作了山西省马铃薯种植气候区划图，该区划结果较为客观地反映了山西省马铃薯种植状况。
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.
