基于GIS的云南栽培型普洱茶树大规模种植适宜性评价

Evaluation of the suitability of large scale plantations of cultivated Puer tea in Yunnan Province based on GIS

本文选取普洱茶树的起源地云南作为研究区,综合考虑普洱茶树的自然立地条件与大规模种植的便利条件,基于GIS空间分析技术,建立栽培型普洱茶树大规模种植用地适宜性评价模型,进而划分适宜性等级、分析统计适宜地区的土地数量和空间分布规律,为大面积推广种植普洱茶树提供科学决策依据。结果表明:1)建立的适宜性评价模型能定量、直观地获取适宜地区的土地数量与空间信息,可操作性较强,具有一定的推广应用价值;2)云南省内,共有面积约为6400km2、占全省土地总面积1.68%的土地比较适宜大规模种植栽培型普洱茶树,还具有较大的规模化种植潜力;3)自然立地条件是决定普洱茶品质及其价值的至关重要因素,普洱茶是云南特有的地理标志产品。

A suitability evaluation model for planting cultivated types of Puer tea on a large scale,using Yunnan Province（the birth place of Puer tea） as our study area,was developed based on geographic information system（GIS） data.After a comprehensive consideration of the natural and social conditions,we analyzed suitability,area and spatial distribution of the land in the most suitable regions.The results show that the model is used friendly and can provide spatial information of land both directly and quantitatively.A total of 6 400 km2 suitable regions in Yunnan Province were found,accounting for 1.68% of the total area,suggesting a greater development potential for large-scale plantations of cultivated Puer tea.Natural conditions are the key factors determining the quality and value of Puer tea,which has become a unique geography signature product of Yunnan Province.
