【摘要】 利用江西省84个气象台站1971—2000年的气候观测资料和站点地理信息资料,建立江西省温度、日照和降水等气候资源的数学推算模型。并在GIS支持下,对模型进行小网格推算和残差订正,保证每个网格点上的气候资源值是比较准确的。同时绘制气候资源分布图,将其与江西省气候资源实际分布情况进行初步分析和比较,发现两者的空间分布趋势具有一致性,而且更加细腻、真实。说明推算模型能够反映江西省气候资源的分布规律,具有良好的统计意义和实际意义,可为气候区划工作奠定良好的基础。更多还原

【Abstract】 Topographic factors and climate observe data during the period from 1971 to 2000 in Jiangxi Province were taken into consideration in terms of the complex geography and distinct tridimensional variety of climate resources in Jiangxi Province.Appliying the small gird simulation methods in the prediction model supported by GIS,the spatial distribution of the length of annual sunshine hours,annual temperature ,annual active accusation temperature and rainfalls were calculated precisely which are expressed visually in the paper.The major characteristics of the spatial distribution of Jiangxi agricultural climate factors were analyzed in terms of the study results and the reality.The results of the study are not only useful for utilizing and developing the local climate resources,but also provide detailed data and scientific support for sustainable development of agriculture .更多还原
