基于GIS技术的云龙县麦地湾梨气候适宜性区划

Climate Suitability Regionalization of Maidiwan Pear in Yunlong County Based on GIS

充分利用云龙县气象站1977—2016年40年逐月地面气象资料,以及云龙县所属的11个乡镇气象观测站订正后的逐月地面气象资料,在总结前人工作成果的基础上,对云龙县麦地湾梨气候资源进行综合性分析;应用GIS技术研究云龙县麦地湾梨种植的气候适宜性,采用自然断点法将云龙县麦地湾梨气候适宜性划分为最适宜区、适宜区、次适宜区、不适宜区等4个层次区域,作出云龙县麦地湾梨气候适宜性区划图,并粗略估算出云龙县麦地湾梨的可种植面积;针对影响云龙县麦地湾梨生产的主要气象灾害,提出对策。云龙县现有的麦地湾梨优质高产区全部均位于区划结果的种植气候最适宜区内,区划结果的实用性强,对云龙县地方特色品种麦地湾梨产业的可持续发展具有较强的参考性。

Making full use of the monthly meteorological datas of Yunlong County Meteorological Station for 40 years from1977 to 2016,and the revised monthly meteorological datas of 11 township meteorological observation stations, based on summarizing the previous work, comprehensive analysis was made on the climate resources of Maidiwan Pear in Yunlong County;The GIS technology was used to study the climate suitability of Maidiwan Pear planting in Yunlong County;the climate suitability of pear was divided into four levels(the most suitable zone, suitable zone, sub-suitable zone and unsuitable zone)based on the natural breakpoint method. The climatic suitability map of Maidiwan Pear in Yunlong County was prepared, and the planting area of Maidiwan pear in Yunlong County was roughly estimated. In view of the main meteorological disasters affecting the production of Maidiwan Pear in Yunlong County, the countermeasures were put forward. The high-quality and high-yield areas of Maidiwan Pear in Yunlong County were all in the most suitable zone.The zoning results were highly practical,and had a strong reference for the sustainable development of Maidiwan pear which was the landrace in Yunlong County.
