| 摘要: |
| 为探讨影响花椒生长发育的主要气候资源和受气象灾害的影响因子,本文根据不同品种的花椒对气候生态条件要求的差异,分析遵义与花椒优生区(重庆江津)气候条件的异同,确定影响遵义市花椒区域分布差异的主要气候生态区划指标,并利用Arcgis和数字高程模型(DEM)对遵义市种植花椒进行气候生态精细化区划。结果表明：九叶青花椒适宜栽培区主要分布在我市西部和北部海拔在900米以下地区种植,区内热量条件充足,冬季遭受低温冻害风险相对小；次适宜栽培区主要分布在我市中部和东南部等海拔为600米到1000米地区,冬季遭受低温冻害风险增大,为25%-40%之间；不适宜区分布在习水、大娄山脉等海拔在1000米到1100米以上的区域,花椒冬季遭受低温冻害风险较大,在50%以上。 |

| Abstract: |
| In order to explore the main climatic resources affecting the growth and development of Zanthoxylum Bungeanum and factors affected by meteorological disasters,in this peper,we applied the climate characteristics of different Zanthoxylum Bungeanum varieties and the mountain climate of Zunyi,then we based on GIS application technology and DEM to determine the climatic and ecological regionalization index that is suitable for the main Zanthoxylum Bungeanum cultivars.We made the refined zoning map,it shows:(1)the suitable cultivation areas for Zanthoxylum armatum．novemfolius are mainly distributed in the west and north of the 900 meters above sea level of Zunyi,the thermal conditions in the area are sufficient and the risk of cold injury in winter is relatively small;(2)sub-optimum cultivation areas are mainly distributed in the central and southeastern regions with an altitude of 600 to 1000 meters, the risk of low temperature damage is increased in winter,ranging from 25% to 40%;(3)the unsuitable areas are distributed in Xishui,Dalou Shan at an altitude of 1000 to 1100 meters above sea level, in this region, the risk of cold injury in winter is higher, above 50%. |
