云南省西畴县猕猴桃种植气候适宜性区划研究

Climate Suitability Zoning of Kiwifruit Planting in Xichou County of Yunnan Province

使用标准时段(1986—2015年)气象资料和地理信息数据(经纬度、海拔、坡向和坡度等),基于地理信息系统对西畴县猕猴桃种植进行气候适宜性区划。根据猕猴桃种植所需的生态气候条件,通过分析年平均气温、年日照时数、年降水量、≥0℃积温、≥10℃积温等气候数据,结合实际情况,最终选择年平均气温、≥10℃积温、年降水量作为研究区核桃生长气候适宜性区划指标。运用GIS技术及SPSS数据分析平台,将西畴县分为猕猴桃生长最适宜区、适宜区、次适宜区、不适宜区,为西畴县猕猴桃推广种植提供科学、合理布局的依据。

Using meteorological data and geographic information data(longitude and latitude,altitude,slope direction,slope gradient,etc.)in standard time period(1986-2015)and the climatic suitability zoning of kiwifruit planting in Xichou County was carried out based on geographic information system.According to the ecological conditions required for kiwifruit planting,the annual average temperature,annual sunshine hours,annual precipitation,≥0℃accumulated temperature,≥10℃accumulated temperature and other climatic data were analyzed.Combined with the actual situation,the annual average temperature,≥10℃accumulated temperature and annual water drop were selected as the climatic suitability zoning indication for walnut growth in the study area.Using GIS technology and SPSS data analysis platform,Xichou County was divided into the most suitable area,suitable area,sub suitable area and unsuitable area for kiwifruit growth,so as to provide scientific and reasonable basis for kiwifruit planting in Xichou County.
