基于GIS的广西木棉物候三维空间演变分析

以自然物候学理论为指导,GIS为技术支持,气象站物候资料、地理信息资料为基础数据,采用多元线性回归分析法,对广西木棉主要物候期的日序与其对应观测站的经度、纬度和海拔高度进行多元回归分析,建立广西木棉物候期三维空间演变模型,制作广西木棉主要物候期三维空间演变专题图,分析广西木棉主要物候随三维空间的变化规律。结果表明:广西木棉主要物候期从低纬度的沿海南部地区向高纬度的北部地区逐渐演变;同一纬度,从低海拔的平地和丘陵地区向高海拔的山区逐渐演变。

GIS-based three-dimensional space evolution of analysis from Gossampinus malabarica phenological phase in Guangxi

The main phenophase of kapok in guangxi were analysed from kapok sequence and its corresponding observatory latitude,longitude and altitude,with natural phenological theory as the guide,GIS for technical support,weather station phenology material and geographic information material for basic data,using the linear multivariate regression analysis method.Then kapok of main period that the three dimensional space evolution model were established in Guangxi,where 3D spatial evolution special charts of main phenophase of kapok were made. It could analyze the change rule of three dimensional space from main phenology kapok in Guangxi. The results showed that the main phenology kapok were evolved gradually in Guangxi from low latitude of the southern coast to hight latitude of the north,and it was evolved gradually from low elevation of the plain and hilly area to high altitude mountainous area as the same latitude.
