广西大石山区农业旱灾脆弱性及抗旱措施研究

Study on the Agriculture Drought Disaster Vulnerability and Anti-Drought Measures in the Karst Area of Guangxi Province

广西大石山区是典型碳酸盐岩溶地貌,易受春旱和秋旱影响,旱灾频率高、范围广、强度大、损失重。本文根据层次分析法和模糊物元法,结合大石山区的实际情况,对广西大石山区农业旱灾脆弱性进行评价,并在剖析大石山区旱灾原因的基础上,根据提高农业抗旱能力与保持生态可持续发展相结合的原则,指出未来工作中应采取的抗旱措施。

The typical carbonate karst landfor,Dashi mountainous area of Guangxi Province is easily affected by the droughts at spring and autumn with the features of high frequency,wide area,large strength and serious loss.On the basis of AHP method and Fuzzy matter element,it was analyzed the drought vulnerability of Guangxi Karst Area combing with the actual situation of the Dashi Mountainous Area.On the basis of the analysis of the drought reasons,it is indicated the countermeasures for the future drought fighting in accordance with the principle of combination of agricultural anti-drought capacity improvement and the sustainable eco-development.
