丰城市干旱灾害成因及抗旱对策

Study on causes of drought disasters and drought resistance measures in Fengcheng city

针对丰城市干旱灾害频繁发生的现象和影响范围,本文从现有的抗旱工程措施和非工程措施等分析了当前的抗旱能力,并从引发干旱灾害的降雨分布不均,天时与农时错位自然气象、抗旱水源工程分布不平衡、输水建筑物老化失效、效益难以发挥和人类活动造成赣江河床下切等因素进行剖析,从加强小型农业灌溉工程建设、加快城乡水源工程建设等抗旱工程措施和强化科学调度蓄水、加强部门通力协作,强化抗旱服务组织建设、完善各项服务机制等抗旱非工程措施的建设提出抗旱对策建议,为今后抗旱决策提供有力依据.

In view of the frequent occurrence and impact of drought disasters in Fengcheng City,this paper analyzes the current drought resistance from the existing engineering measures and non- engineering measures,it also analyzes a series of factors,namely the uneven distribution of rain caused by drought,the dislocation of natural phenomenon between Tian Shi and Nong Shi,the unbalanced distribution of drought- resistant water resource,the aging and low efficiency of water- supply structures,the Gangjiang riverbed entrenchment caused by human activities. So it puts forward drought resistance suggestions to engineering measures of strengthen the project construction of small agricultural irrigation and water resource,to non- engineering measures of strengthen scientific water dispatching,departmental collaboration,service organization construction and improvement of the service system,which provides important reference for the future drought resistance measures.
