宁夏回族自治区酿酒葡萄气候区划

Climatic Zoning of Grapevine in Ningxia Hui Autonomous Region

通过对宁夏回族自治区24个一般站点30年(1979—2008)的气象资料进行统计分析,按照李华等提出的气候区划指标体系,详细的分析了各区划指标在宁夏的分布情况。以无霜期为一级指标,干燥度(4—9月)为二级指标,埋土防寒线为第三指标,对宁夏进行气候区划。本文将宁夏划分为5个区域,其中1个为不适宜种植葡萄区,主要分布于固原全部、中卫市和吴忠市的部分地区,这些地区的限制因素是无霜期太短;其他区域为适宜区,适宜区可细分为4个区域,其中1区和3区主要集中在贺兰山东麓一带,无霜期适合,干旱少雨且有引黄灌溉的便利条件,是种植酿酒葡萄的优质产区。本文并对各区适合种植的品种种类做了初步评价。

Based on the climate data of 24 meteorological stations in the past 30 years （1979--2008）, the climatic zoning of grapevine in Ningxia Hui Autonomous Region is discussed and classified according to the system proposed by Li Hua, et al. In the climatic zoning system, the number of frost free days is used as the first index, the dryness index （from April to September） as the secondary index and the mean lowest temperature below -15℃ as the tertiary index. By applying this zoning system, the distribution of indicators is analyzed, and on this basis, Ningxia Htii Autonomous Region is divided into 5 regions, the unsuitable area, mainly located in Guyuan, Wuzhong city and parts of Zhongwei City, where the frost-free period is too short; and the other four regions. The first and third areas are mainly along the eastern foot of Helan moutain, where frost-free period is suitable, drought but with convenient irrigation conditions, and high quality grapes can be produced. An evaluation on the varieties of grapes suitable in every zone is made.
