摘要
根据甘蔗生长与气候条件的关系,分析确定了广西甘蔗种植的农业气候区划指标;利用广西90个气象台站30a的气候资料和台站地理信息,建立了区划指标的空间分析模型。在GIS的支持下,考虑地形的影响,按1km×1km细网格推算出无测站地区气候区划因子的空间分布,并对广西甘蔗的适宜种植区进行农业气候区划,为优化广西甘蔗布局以及趋利避害提高产量和含糖量提供科学依据。
According to the relationship between sugarcane growth and climate conditions, Indexes for agro-climate division of sugarcane planting were determined. By using the climate and geographic data recorded in the 90 meteorological stations for 30 years in Guangxi Zhuang Autonomous Region, the spatial distribution models of division index were established. The spatial distribution of division indexes in no-station regions was calculated on grids of 1km× 1km based on GIS. The suitable planting areas for sugarcane in Guangxi Zhuang Au tonomous Region were divided to provide the scientific basis for optimizing distribution of sugarcane planting.
