分析了影响三峡库区甜橙生长发育的主要气候资源和气象灾害,并根据不同甜橙品种类型及鲜食甜橙与加工甜橙对气候生态条件要求的差异,确定了影响三峡库区甜橙分布的主要气候生态因子及指标;采用回归模拟或插值等方法,利用Arcgis和1∶25万DEM(区、县用1∶5万)研究了年总辐射、年平均气温和年平均相对湿度等区划因子的空间分布,以此为基础,制作了三峡库区甜橙精细化气候生态区划;根据区划结果进行了分区评述,并提出了三峡库区甜橙发展战略.
The main climatic resources and meteorological disasters affecting the growth and development of sweet orange in the Three Gorges Reservoir Area were analyzed. According to the differences in the requirements of climatic and ecological conditions between different sweet orange varieties and sweet oranges and processed sweet oranges, Distribution of major climatic ecological factors and indicators; using regression modeling or interpolation methods, using Arcgis and 1: 250000 DEM (1: 50000 for districts and counties) to study the annual total radiation, the annual average temperature and the average annual relative humidity According to the spatial distribution of zoning factors, the refined zoning of sweet orange climate in the Three Gorges Reservoir Area was made. Based on the zoning results, zoning comments were made and the development strategy of sweet orange in the Three Gorges Reservoir Area was proposed.
