昭平县基于GIS技术的茶树种植气候区划

Climate division of tea planting based on GIS technology in Zhaoping County

基于GIS技术,利用茶树的生长发育条件与气候之间的相关关系,研究昭平县内茶树种植的农业气候区划。利用昭平县1:25万基础地理数据和昭平县气象站近30a的气候资料,建立区划指标的高层模型,并采用GIS技术对研究区的茶树种植进行气候区划,可划分为四个区,即最适宜种植区、适宜种植区、次适宜种植区以及不适宜种植区。针对各个区不同的气候特征,提出相对应的茶树种植建议,为昭平茶叶的种植和生产发展提供科学参考。

Based on GIS technology,this paper studied the agroclimatic division of tea planting in Zhaoping County by using the correlation between the growth conditions of tea trees and climate.Based on the 1:250,000 basic geographic data of Zhaoping County and the climatic data of Zhaoping meteorological station in the past 30 years,a high-level model of regionalization index was established.The climatie regionalization of tea planting area was carried out by using GIS technology,which can be divided into four areas,namely,the most suitable planting area,the suitable planting area,the sub-suitable planting area and the unsuitable planting area.Besides,according to the different climate characteristics of each region,the corresponding tea planting suggestions were put forward,which can provide scientific reference for the tea cultivation and production development in Zhaoping.
