【 摘 要 】

Drought is a major issue that humanity confronts with and due to its vast ramifications, it is also most difficult to solve. Being a natural phenomenon, it has various manifestations which scalars have categorized into meteorological, agricultural, hydrological, environmental and others, in order to better define and understand this phenomenon. Several drought indices have been proposed by different scholars for measuring it which take rainfall, temperature, sun shining and other features into account. This of course, led to a variety of interpretations which makes the phenomenon even more difficult to size up and quantify its devastating effects on a longterm scale. The seven indexes this paper makes use of, for calculating drought are: N. Topor index, De Martonne index, Domuta hydroheliothermal index, Selianinov hydrothermal index, Palfai drought index and Lang rain index. In this paper, the case study conducted for Banloc in the 1980-2014 period reveals alternating wet and dry periods which do not pose any threat of aridization or desertification soon. However, a constant monitoring is imposed for these phenomena not to occur, made by the authorized law enforcement together with specialists from various fields.
