摘要
采用崇左市及周边地区共20个国家气象观测站1991—2020年气象资料,根据澳洲坚果的生长特性及前人的研究结果确定澳洲坚果的气候区划指标,运用回归分析法建立崇左市澳洲坚果种植气候区划指标模型,采用GIS技术对崇左市澳洲坚果种植进行气候区划,分析澳洲坚果在不同气候条件下的种植适宜性。结果表明,崇左市及周边地区的年平均气温、年降水量、最冷月平均气温、日平均气温≥10℃年积温等气候区划指标与经度、纬度和海拔等地理因子的相关性较高,受地形影响较明显。崇左市大部分区域处于澳洲坚果种植气候最适宜区,其中龙州县、凭祥市、江州区、扶绥县、天等县县域附近区域、宁明县及大新县大部分区域处于澳洲坚果种植的气候最适宜区。
Based on the meteorological data of 20 national meteorological observation stations in Chongzuo City and its surrounding areas from 1991 to 2020,the climate regionalization index of Macadamia Nut was determined according to the growth characteristics of Macadamia Nut and previous research results,and the climate regionalization index model of Macadamia Nut planting in Chongzuo City was established by regression analysis.The planting of Macadamia Nut in Chongzuo city was divided by GIS technology,and the planting suitability of Macadamia Nut under different climatic conditions was analyzed.The results show that the climatic regionalization indexes such as annual mean temperature,annual precipitation,mean temperature of coldest month and annual accumulated temperature of daily mean temperature ≥10 ℃ in Chongzuo City and its surrounding areas are highly correlated with geographical factors in terms of longitude,latitude and altitude,and are significantly affected by terrain.Most of Chongzuo City is in the climatic optimal zone for Macadamia Nut planting,among which Longzhou County,Pingxiang City,Jiangzhou District,Fusui County,Tiandeng county and most of Ningming County and Daxin County are the climatic optimal zone for Macadamia Nut planting.
