【摘要】：气候环境是影响马铃薯生长发育的至关重要因素之一,为了对云南省的马铃薯种植进行气候适宜性区划,以云南省境内125个气象监测站测得的温度、降水、日照时数等气象数据和云南省地理信息数据为基础,结合前人对马铃薯生长的生理生态研究成果,通过专家打分法和层次分析法等技术手段建立了云南省马铃薯种植气候适宜性评价指标体系。该评价体系包括"生育期平均气温""生育期降雨量""生育期日照时数""云南省7月平均气温"和"云南省地理海拔高度"5个评价指标,将每个指标划分为"最适宜区""适宜区"和"次适宜区"3个区域。在该评价体系的基础上构建了综合评价模型,运用地理信息系统(GIS)技术,对云南省马铃薯种植的气候适宜性进行了区域划分。结果显示,马铃薯最适宜种植区占云南省的24.6%,适宜区占56.1%,次适宜区占13.9%。研究结果可为云南省马铃薯科学种植规划提供参考依据。
[Abstract]:Climatic environment is one of the most important factors affecting potato growth and development. In order to regionalize the climate suitability of potato cultivation in Yunnan Province, the temperature and precipitation measured by 125 meteorological monitoring stations in Yunnan Province are used. Based on meteorological data such as sunshine hours and geographic information data of Yunnan Province, combined with previous studies on physiology and ecology of potato growth, The evaluation index system for climate suitability of potato cultivation in Yunnan Province was established by means of expert scoring method and analytic hierarchy process (AHP). The evaluation system includes five evaluation indexes: "mean temperature during growth period", "precipitation in growing period", "sunshine duration in growing period", "mean temperature in July of Yunnan Province" and "Geographic altitude of Yunnan Province". Each index is divided into "most suitable area" and "sub-suitable area". On the basis of the evaluation system, a comprehensive evaluation model was constructed, and the climatic suitability of potato cultivation in Yunnan Province was divided by using (GIS) technology. The results showed that the most suitable planting area for potato was 24.6% in Yunnan province, 56.1% in suitable area and 13.9% in sub-suitable area. The results can be used as a reference for potato planting planning in Yunnan province.
