| 摘 要： | 桂中地区降水不少，但旱情严重，成为广西的著名旱片之一。该文在概述地质地理特征的基础上，进行桂中旱区的旱情时空分析，进而揭示其成因机制；并根据干旱类型、旱灾脆弱度以及便于地下水利用进行桂中旱片的综合区划；秉承生态环境治理、综合抗旱与脱贫致富相结合原则，指出其治理对策措施。

| Abstract: | Because of relatively abundant precipitation but severe ravages of a drought,the middle Guangxi area turns to one among obviously drought tracts of Guangxi.Investigating mechanism of formation is the scientific foundation of environmental harness and regional development in the middle Guangxi.On the basis of summarizing geological characteristics and geographic features,spatial-temporal analyses are carried out on the drought of the middle Guangxi,and its formation mechanism of the drought tracts is revealed emphatically. And then,the comprehensive division of drought tracts in the middle Guangxi is carried through in the link of dry types,drought frail degree and convenience to groundwater utilization.Finally,taking the principle of uniting eco-environmental fathering,integrating anti-drought and shaking off poverty,the countermeasures are pointed out. |
