【摘要】：基于贵州西部红心猕猴桃种植区2005-2014年逐日气温、降水资料,依据贵州85个气象观测站1981-2010年逐旬、逐月、逐年平均气温、降水量、日照时数和极端最高、最低气温以及观测站和1462个乡镇的地理信息数据,应用经验正交函数分解法和模糊聚类法,通过分析贵州省西部红心猕猴桃各生育期的气候条件,得到红心猕猴桃种植的气候适宜性区划指标,采用GIS技术对红心猕猴桃种植进行气候适宜性区划。结果表明:年平均气温、历年极端最低气温(80%保证率)、1月平均气温、3月平均气温、7月平均气温、8月昼夜温差、年降水量、年日照时数可作为红心猕猴桃种植的气候适宜性区划指标,每个指标分4级,对应最适宜、适宜、次适宜和不适宜,红心猕猴桃种植最适宜区在贵州西部地区,适宜种植区在贵州中部偏西地区,次适宜种植区在贵州中部,不适宜种植区主要分布在遵义市、铜仁市、东南部局部和西部边缘。调查表明,贵州山区红心猕猴桃实际种植情况与气候适宜性区划结果基本吻合。
[Abstract]:Based on the daily temperature and precipitation data from 2005 to 2014 in Hongxin kiwifruit planting area in western Guizhou, the annual mean temperature, precipitation, sunshine hours and extreme temperature were the highest in 85 meteorological observation stations in Guizhou from 1981 to 2010. Using empirical orthogonal function decomposition method and fuzzy clustering method, the climatic conditions of Actinidia chinensis in each growing period of Actinidia chinensis in western Guizhou Province were analyzed by using the minimum temperature and geographic information data of observation stations and 1462 towns. The climatic suitability regionalization index of Actinidia chinensis planting was obtained, and the climatic suitability regionalization of Actinidia chinensis planting was carried out by GIS technique. The results show that the annual mean temperature, the extreme minimum temperature of every year is 80% guarantee rate, the average temperature in January, the average temperature in March, the average temperature in July, the temperature difference between day and night in August, and the annual precipitation. The annual sunshine hours can be used as the climatic suitability regionalization index of Actinidia chinensis cultivation. Each index can be divided into 4 grades, corresponding to the most suitable, secondary and unsuitable areas, and the most suitable area for the cultivation of Actinidia chinensis is in the western part of Guizhou. The suitable planting area is in the west of central Guizhou and the secondary planting area is in the middle of Guizhou. The unsuitable planting area is mainly distributed in Zunyi City, Tongren City, the southeast part and the western margin. The investigation shows that the actual planting situation of Actinidia deliciosa in Guizhou mountainous area is basically consistent with the result of climatic suitability regionalization.
