摘要
为探索水田农业区农业旱灾恢复力变化的内外驱动力、影响恢复力提升的制约因素,基于灾害系统理论,以水田农业典型区湖南鼎城为研究区,对其乡镇农业旱灾恢复力的时间变化和空间分布进行评价分析。结果表明,两类评价结果具有较高的吻合度,优质水田面积扩大、作物种植结构改变和农民收入增加是农业旱灾恢复力提升的重要因素。
The agricultural drought resilience in temporal variation and spatial distribution of villages and township were evaluated and analyzed to explore inside and outside driving forces of agricultural drought resilience change and constraints influencing the resilience enhancing based on disaster system theory.Results showed that evaluation results based on temporal variation and spatial distribution had a higher match degree,and the key factors for improvement of agricultural drought resilience included expanding the area of high-quality paddy field,changing crop plantation structure and increasing farmers＇ income.
