伊犁河谷树上干杏的气候区划

Climatic Regionalization of Shushanggan Apricot in the Ili River Valley

基于1991-2020年伊犁河谷及其周边20个国家气象观测站的气象资料,根据树上干杏的生物学特性及影响其生长发育的主要气象因子,筛选出树上干杏种植气候适宜性区划指标,建立树上干杏气候适宜性区划指标的空间分布模型,通过重分类法将4类区划指标叠加处理,绘制伊犁河谷树上干杏种植气候适宜性区划图,为提高气候资源的利用率,合理划分伊犁河谷树上干杏的气候适宜种植区提供参考。结果表明:伊犁河谷树上干杏种植可划分为最适宜种植区、适宜种植区、次适宜种植区和不适宜种植区。最适宜、适宜种植区位于伊犁河谷北部、乌孙山北部及新源县东部海拔700-1200m河谷平原及浅山地带;次适宜区分别位于海拔<700m和1200-1500m的河谷平原及低山地带;不适宜区位于河谷海拔1500m以上的中高山区。

Climatic suitability rationalization indicators based on meteorological data were collected from 20 national meteorological observation stations in and around the Ili River Valley from 1991 to 2020 to optimize agricultural planting structures,improve the utilization of climate resources,and effectively regionalize suitable planting areas for Shushanggan apricot in the Ili river valley.Additionally,the biological characteristics of the Shushanggan apricot and the key meteorological factors were influencd its growth and development.Subsequently,to develope a spatial distribution model for these climatic suitability indicators.By reclassifying and overlaying the four regionalization indicators,a comprehensive climate-appropriate regionalization for Shushanggan apricot was obtained cultivation in the Ili river valley.The analysis revealed that the cultivation of Shushanggan apricots in the Ili River Valley can be categorized into four distinct areas:most suitable,suitable,sub-suitable,and unsuitable.The most suitable planting areas are predominantly situated in the river valley plains and low mountainous regions,with altitudes ranging between 700 and 1200 m,particularly in the northern part of the Ili River Valley,the north segment of Wusun mountain,and the east segment of Xinyuan county.Sub-optimal planting areas are found in river valley plains and low mountainous regions,with altitudes below 700 m and between 1200 and 1500 m.Conversely,unsuitable planting areas are in mid-low mountainous regions above 1,500 m.These findings provide valuable insights for governmental bodies seeking to optimize agricultural cultivation structures in the Ili River Valley.
