摘要: |
目的 为合理利用吉林省气候资源、优化吉林省马铃薯种植布局,基于气候和马铃薯生长周期开展吉林省马铃薯种植气候适宜性区划研究具有重要意义。方法 文章以1981—2010年吉林省及周边51个气象监测站点的逐日气象资料为基础,根据吉林省的气候特征、马铃薯的块茎增长速度、生育周期等特点,确定以生育期平均气温、生育期降水量、生育期日照时数、生育期≥10℃有效积温及7月份平均气温作为气候区划指标。采用GIS技术提取坡度和坡向等空间信息,将0.01°×0.01°网格作为可推算的最小空间单元,建立基于地理关系的马铃薯种植气候因子空间分析模型推算各气候要素,并对气候区划指标进行残差订正,最后依据马铃薯气候适宜指数等级指标进行气候区划。结果 吉林省马铃薯种植最适宜区主要分布在中西部平原及丘陵地区,占总面积的49.4%;适宜区主要分布在中东部丘陵及低山地区,占总面积的36.9%;次适宜区主要分布在高海拔寒冷地区,占总面积的13.7%。将区划结果与吉林省马铃薯种植状况进行对比,验证了以上区划方法的科学性和合理性。结论 研究结果可为吉林省各区县马铃薯种植生产布局提供参考依据。 |

Abstract: |
In order to utilize all climate resources and optimize the potato cultivation layout in Jilin, it is important to evaluate the climate suitability zone for potato cultivation based on climate variability and potato phenology. This study used the daily meteorological data of 51 stations in 30 years (1981-2010) in Jilin and its surrounding areas, calculated the climate characteristics according to the main factors of potato cultivation and tuber growth rate and cycle, and then selected 5 major indices for potato cultivation layout (i.e. average temperature, effective accumulated temperature above 10℃, precipitation and sunshine hours during growth season, and average temperature in July). The spatial information was also extracted from the digital surface model with 0.01°×0.01° grids (i.e. longitude, latitude, elevation, slope and aspect), and then used to revise the climatic regionalization index. The results indicated that the most suitable areas of potato cultivation in Jilin were mainly in the plain and hilly areas for the central-western regions (accounting for 49.4% of the total area). The suitable areas were mainly in the hilly and low mountain areas for the central-eastern regions (accounting for 36.9% of the total area). The sub-optimal areas were mainly in the cold areas with high altitudes (accounting for 13.7% of the total area). The results of regionalization had a good agreement with the current farmer practices of potato cultivation in Jilin. It concludes that this study can provide reference for potato planting production layout in Jilin province. |
