【摘要】 在生物地理学研究、栽培草地引种、退化草地改良及农牧业发展规划编制过程中,对气候因子的评估是一个首要环节。而在评估气候因子时,如何能够快捷、经济、有效地获取目标区域的气候资料,对整个气候评估工作具有重要的现实意义。DIVA-GIS是一款免费的地理信息系统软件,本研究以实例的形式从免费气候数据获取的途径、DIVA-GIS软件气候功能组件的使用步骤及输出结果的生物气候变量的意义等环节,详尽地介绍了一种基于DIVA-GIS快速获取气候信息的方法。由于DIVA-GIS平台本身的开放性、易用性优势,该方法具有气候数据获取的难度及经济成本低,操作方式简单易上手的特点。更多还原

【Abstract】 To obtain climatic data quickly and easily is apparently essential for researching biogeography,introducing forage species, improving deteriorated grassland and planning agriculture & animal industry.DIVA-GIS is a free computer program for mapping and geographic data analysis, and can be used for manydifferent purposes. With DIVA-GIS, users can map and query free spatial climatic data for the whole world.Here, a method for rapid obtaining of climate data based on DIVA- GIS was presented step by step. Themethodology was easy to apply and the technique was rapid, repeatable and flexible, and did not requiresubstantial financial or scientific input.更多还原
