Abstract:

Agriculture is the main industry of Jiangxi Province,and Jaingxi Province is the important base of food and cotton production in China. Heavy drought happened frequently in the last ten years, and it caused huge loss of agriculture production and damaged the sustainable development of agriculture. This paper collected and analyzed the relative references and the date of agricultural disaster from Jiangxi Agriculture Department, combining with the filed survey on agricultural disaster in Duchang and Xingzi County with the high drought index. The influence of drought on agriculture development of Jiangxi Province was discussed and the driving forces of agricultural drought disaster were assessed. The results showed that the drought stress frequently happened in autumn and decreased food and cotton production of Jiangxi Province, especially in Poyang Lake area. The forces driving agricultural drought disaster included uneven distribution of precipitation, red soil with low water holding capacity, old irrigation and water conservation facility not working efficiently, destroyed plant pattern conserving water and building large water conservancy facility liable to chang hydrological process. In the last,based on the above mentioned driving forces,this paper suggested the integrated and effective countermeasure to alleviating agricultural drought disaster
