南丰蜜橘高接换种冻害发生气候风险区划

Climatic Risk Zoning of Freezing Injury in High Grafting of Nanfeng Tangerine

选用1958—2022年南丰县气象资料,从气候条件角度出发,分析低温冻害对南丰蜜橘高接换种的影响,由此确定南丰蜜橘高接换种发生冻害的有利气候条件指标。同时运用Arcgis对南丰县南丰蜜橘高接换种树体冻害发生气候风险区进行划分,主要划分为高风险、中风险、低风险、无风险4个风险区。无风险区包括白舍镇、紫霄镇小部分地区、付坊乡;低风险区包括白舍镇、紫霄镇、太和镇中北部地区、太源乡、桑田镇中南部地区;中风险区包括东坪乡、莱溪乡、洽湾镇、琴城镇、三溪乡、市山镇、桑田镇北部、太源乡北部、白舍镇及紫霄镇靠近三溪乡军峰山山区;高风险区主要为市山镇靠近军峰山地区及军峰山高海拔山区。

Based on the meteorological data of Nanfeng county from 1958 to 2022,the impact of low temperature freezing injury on the high grafting of Nanfeng tangerine were analyzed,so as to determine the favorable climatic conditions for the occurrence of freezing injury in the high grafting of Nanfeng tangerine.At the same time,Arcgis was used to classify the climatic risk of freezing injury of Nanfeng tangerine high grafting in Nanfeng county,which was mainly divided into four risk areas:high risk,medium risk,low risk and risk free.The risk free areas included Baishe town,a small part of Zixiao town and Fufang township;The low risk areas included Baishe town,Zixiao town,the north central area of Taihe town,Taiyuan township,and the south central area of Sangtian town;The Medium risk areas included Dongping township,Laixi township,Qiawan town,Qincheng town,Sanxi township,Shishan town,the north of Sangtian town,the north of Taiyuan township,Baishe town and Zixiao town near Junfeng mountain of Sanxi township;The high risk areas were mainly Shishan town near Junfeng mountain and Junfeng mountain high-altitude mountainous area.
