香格里拉地区酿酒葡萄生长区域气象因子的分析

环境因素直接影响着葡萄的生长和品质,利用自动气象观测仪监测气象数据来研究香格里拉地区这种低纬度、高海拔的特殊地理环境的气象因子,初步分析了位于金沙江沿岸与澜沧江沿岸不同海拔、不同经纬度的6个气象站主要气象因子的变化规律,分别分析葡萄开花期（5月上旬～6月上旬）、转色期（7月上旬～9月上旬）、采摘期（9月中旬～11月中旬）的各种气象因子的变化规律;此外还利用USB4000 Fiber Optic Spectrometer采集分析了香格里拉地区太阳光谱的分布规律.结果显示,香格里拉地区降雨量普遍较少,总辐射、紫外线辐射普遍较大,温差变化比较显著,相对湿度变化较小;太阳光中各种光谱分布规律基本一致,太阳光强度随海拔升高不断升高.

Analysis on the Meteorological Factors in the Wine Grape Growing Region of Shangri-La Area

Environmental factors directly affect the growth and quality of grape. The meteorological data is collected and monitored by auto- matic weather observation instruments to study the meteorological factors in latitude and high altitude particular terrain environment of Shangri- La region. Meanwhile, this paper does a preliminary analysis of the correlation of key meteorological factors of 8 meteorological stations in dif- ferent altitude, latitude and longitude along the Jinsha River and Lantsang River. According to the rule of the variation of meteorological ele- ments, the change laws of various meteorological factors of wine grape are analyzed respectively in the period of flowering （ early May to early June）, discoloring （ early July to early September）, and picking （ in the middle of the middle of September to November）. In particular, USB4000 Fiber Optic Spectrometer is used by collecting and analyzing the distribution of the solar spectrum in Shangri-La area. It is found that, Shangri-La area has less rainfall, bigger total radiation and ultraviolet radiation, significant temperature changes, smaller relative humidi- ty changes, almost identical various spectral distribution regularity in the sun, and increasing sunlight intensity with altitude rising.
