摘要
利用广西89个气象站1961-2016年气象观测资料和广西1∶5万基础地理信息数据,采用MeteoGIS技术和气候资源细网格模拟分析方法,结合广西早稻实际生产情况,建立了广西早稻高温热害的空间模拟分析模型,运用反距离权重插值法对高温热害区划指标因子进行100m×100m细网格模拟推算和残差订正,并综合考虑高温热害区划指标等级,对广西早稻高温热害发生分布进行了精细化区划.将广西早稻区分为基本无高温热害区、轻度高温热害区、中度高温热害区、较重高温热害区和严重高温热害区5个区域,分区结果符合广西早稻高温热害实际情况,为水稻生产的趋利避害、优化布局和科学防灾减灾提供科学依据.
In order to provide scientific evidences for optimizing rice cultivation structure and preventing and mitigating disaster-caused losses, a spatial analyzing model of high temperature heat injury of early rice in Guangxi was established, using the technology of MeteoGIS and fine-grid simulation of climate resources, based on the meteorological data of 89 meteorological observatories in Guangxi during1961-2016 and the Guangxi fundamental geographic data on the scale of1∶50 000. The method of inverse distance weighting was used to calculate the index factors of heat injury and revise their residual differences by100 m ×100 m fine grids. Taking into consideration the results and the indicator system of high temperature heat injury, a fine regionalization of the distribution of the heat injury of early rice in Guangxi was made, in which five zones were identified : none-disaster zone, light disaster zone, moderate disaster zone, heavy disaster zone and serious heavy disaster zone. The above results were well consistent with the actual situations in early rice-growing regions in Guangxi.
