贵州省油茶的生态适宜性评价及种植区划研究

Ecological Suitability and Planting Regionalization of Camellia oleifera in Guizhou Province

介绍了油茶的生态适宜性评价指标体系的选择原则、方法和评价依据,以此为依据对贵州省油茶林栽培区进行了适宜性评价,将贵州油茶林栽培区划分为3个等级:最适宜栽培区、适宜栽培区、较适宜栽培区。其中最适宜栽培区主要分布在贵州省东部和南部地区,为油茶产业发展的重点地区,占全省总面积的31.90%;适宜栽培区主要分布在中部地区,占全省总面积的29.00%;较适宜栽培区主要集中在西部地区,占全省总面积的9.30%。

The paper introduces the selection principles,methods and evaluation criteria of the index system for evaluating the ecological suitability of Camellia oleifera,based on which the suitability of the Camellia oleifera cultivating area in Guizhou Province was evaluated and categorized into three levels of the optimal cultivating area,suitable cultivating area and less suitable cultivating area.The optimal cultivating area was mostly distributed in East and South Guizhou Province,it was the key area of Camellia oleifera industry,occupying 31.90% of the total province.The suitable cultivating area was mainly distributed in Central Guizhou Province,covering 29.00% of the total province.The less suitable area mainly concentrated in West Guizhou,accounting for 9.30% of the total provincial area.
