湖南鼎城水田农作区农户农业旱灾后恢复力评价研究

Evaluation of Agricultural Resilience of Households after Drought in Paddyfield in Dingcheng in Hunan Province

以水田农业典型区——湖南鼎城为研究区域,采用入户问卷调查的形式,运用主成分分析法对农户农业旱灾后的恢复情况进行评价分析。结果发现:被调查的各乡镇农业旱灾后恢复力存在较大差异。农户农业旱灾后恢复力随着人均粮食产量的增加先升高后降低;随着人均家庭收入增加出现了"M"型趋势;不同地貌类型的农户农业旱灾后恢复力排序为东北部地区>西北部地区>南部地区>中部地区;家庭收入水平、地貌类型和作物种植结构对农户农业旱灾后恢复力地提升有较大影响。最后,根据调查分析结果提出了几点具体措施,以帮助鼎城区农户提升农业旱灾后的恢复力。
