| 摘 要： | 以自然条件下大气-作物-土壤系统的水量平衡方程为基础，结合广西干旱灾害特点，建立广西农业干旱评估模型。与广西历史农业旱情实况对比分析表明，该模型能够较客观、定量地对农业干旱的发生、发展过程进行逐日动态监测和灾中、灾后评估。

| Abstract: | This paper establishes the Guangxi agriculture arid appraisal model based on the water volume balance equation of the atmospheric - crops - soil system under the natural conditions combining with Guangxi arid disaster characteristic. Compared with Guangxi history agriculture drought situation, this model can dynamically monitor the occurrence and developing process of agricultural arid day after day in terms of objective and quota, as well as the disaster appraised. |
