摘要:

气候条件和生长周期对于高粱种植至关重要,合理的利用山西省气候资源,对优化高粱种植布局具有重要意义。本文对1979—2020年山西省109个气象监测站点的逐日气象资料进行分析和总结,将高粱生育期内的平均气温、降水量、日照时数、≥10℃有效积温及全年的无霜期数据作为气候区划的参考因子,采用GIS技术进行数学建模,推算基于地理关系的高粱种植气候因子空间的各气候要素,并对气候区划指标进行反馈矫正,最后建立了基于气候适宜指数等级指标的高粱气候区划。结果表明:山西省最适宜高粱种植的区域位于吕梁山西侧的大部分县(区)和山西省其他大部分盆地区域,占总面积的41%;次适宜区主要分布在山西省内海拔相对较低的平原或低山区域,占总面积的42%;不适宜区主要分布在山西省内高海拔寒冷地区,占总面积的17%。本文研究阐明了山西省气候条件和生长周期对高粱种植的重要意义,可为山西省各县(区)的高粱种植生产提供科学合理的布局参考依据。

Abstract:

Climatic conditions and growth cycle are crucial for sorghum planting. To optimize the layout of sorghum planting in Shanxi Province, it is important to fully and rationally use the climatic resources. In this work, we analyzed and modeled the daily meteorological data to establish the sorghum climate regionalization based on the climatic suitability grade, in which the data were collected from 109 meteorological monitoring stations in Shanxi Province ranging from 1979 to 2020. Specifically, we adopted the related climatic indices as the experimental indices for the sorghum climate regionalization, which included the average temperature, precipitation, sunshine hours, effective accumulated temperature ≥10℃, and the annual frost-free period data during the sorghum growth period. GIS method was utilized to calculate the climatic elements of the sorghum planting and correct the climatic indices of regionalization based on the geographical relationships.

The experimental results indicated that the most suitable areas for sorghum planting in Shanxi Province located in most counties (districts) on the west side of Lvliang Mountain and most other basins in Shanxi Province, which accounted for 41% of the total area. The sub-suitable areas were mainly distributed in low plains or low mountain areas of Shanxi Province, which accounted for 42% of the total area. Unsuitable areas were mainly distributed in high-altitude and cold areas in Shanxi Province, which accounted for 17% of the total area. This work demonstrated the significance of climatic conditions and the growth cycle for sorghum planting in Shanxi Province. It could provide a scientific basis for sorghum planting and production in all counties (districts) in Shanxi Province.
