普洱市烤烟种植生态区域气候因素分布规律研究

Pu'er City Flue-cured Tobacco Planter Ecology Regional Climate Factor Distributed Rule Research

本研究应用GIS和GPS技术,进行气候要素的空间分析和要素之间相互关系的研究,模拟推算得出普洱烟区基本气候要素的地理空间分布细网格模拟数字地图,并与滇中烟区气候条件进行比较。结果显示:多个气候要素的变化具有较好的一致性和协调性,7—8月气候条件对烤烟种植和烟叶品质的影响起主导作用;普洱烟区与滇中烟区比较,普洱烟区3月至5月上旬气温较高、日照时数相当或略少、降水略多但总体仍为少雨,6—8月日照时数比滇中烟区明显偏少、雨量显著偏多。普洱烤烟大田生长前、中、后期气温都很适宜、育苗期和大田前期多光少雨是普洱烤烟气候的主要优势,6—8月多雨、日照偏少是其的明显不足;普洱市气候地域差异大,部分区域如墨江站和部分海拔相对较低的河谷区,光照热量条件较好、雨季雨量适中,是普洱市烤烟生产潜力较大的区域。

Through the application of GIS and GPS technology,spatial analysis of climatic factors and elements and the relation between the factors were studied.This study also simulated extrapolated the digital map about the Pu ＇ er fundamental climatic elements distribution,and compare Pu ＇ er climatic elements with the central areas in Yunnan.The results showed that multiple climatic factors change had better coherence and coordination,July and August ＇ s climate conditions play a leading role on tobacco cultivation and tobacco quality;From March to early May,Pu ＇ er areas had higher temperatures,equal or slightly less sunshine duration,compared with central area in Yunnan;From June to August sunshine hours of Pu ＇ er tobacco area was significantly lower than central areas of Yunnan,rainfall was significantly more than central areas in Yunnan.The temperature were suitable during the time Pu ＇ er flue-cured tobacco growth,seedling stage and datian light was quite rainy climate of the main advantages of flue-cured tobacco,from June to August rain,sunshine were low.So Pu ＇ er City was obviously suitable for tobacco production.
