基于Surfer技术的广西甘蔗低温寒冻害空间分布研究

Study on spatial distribution of low temperature cold frost damage of sugar cane in Guangxi based on Surfer technology

利用广西91个国家级气象观测站1961-2016年的气象资料,计算出广西甘蔗低温寒冻害轻、中、重、严重发生频率,基于Surfer技术获得广西甘蔗低温寒冻害轻、中、重、严重发生频率的空间分布特征图。纬度越高甘蔗低温寒冻害轻、中、重、严重发生频率越高,纬度越低,出现的频率越小,根据甘蔗低温寒冻害空间分布图,划分出广西无低温寒冻害区、轻度低温寒冻害区、中度低温寒冻害区、重度低温寒冻害区以及严重度低温寒冻害区。

Based on the meteorological data of 91 national meteorological observation stations in Guangxi from 1961 to 2016,calculating the frequency of low temperature cold frost damage of light,medium,heavy and serious in Guangxi province.The spatial distribution characteristics of low-temperature cold frost damage of sugar cane were analyzed through S urfer software.The results showed the higher latitude,the lighter damage of light,medium,heavy,and severe frequency,and the lower latitude,the lower frequency occurrence.According to the spatial distribution of sugar cane cold and freezing injury,Guangxi province was divided into not damage zone,mild damage zone,moderate damage zone,heavy damage zone and severe damage zone.
