    摘要:

    为优化永丰县农业水土资源配置,提升农业生产效率,基于2024年永丰县现场调研数据,通过计算基尼系数、水土资源匹配系数及水资源利用效率,对永丰县农业水土资源的匹配程度进行评价。结果表明:整体上,2024年永丰县农业用水量与耕地资源匹配的基尼系数为0.005 6;从分区水土资源的匹配系数来看,官山林场的水土资源匹配系数最高,达2.08,上溪乡的水土资源匹配系数最低,仅为0.51,其他大部分乡镇匹配系数均在0.51至0.58之间,2024年永丰县农业水土资源在空间上相对均衡。2024年永丰县平均灌溉面积覆盖率为26.70%,复蓄指数为0.46;从水资源状况分析结果来看,水库山塘存在蓄水容积不足的问题,在当地农业生产中灌溉作用比较有限,建议通过科学合理地规划水土资源配置,提高水资源利用效率。

    Abstract:

    This study analyzes the current matching degree of agricultural land and water resources in Yongfeng County,aiming to optimize the allocation of local agricultural water-land resources and enhance agricultural production efficiency.Based on field research data collected in Yongfeng County in 2024,the matching degree is evaluated by calculating the Gini coefficient,water-land resource matching coefficient,and water use efficiency.The results indicate that the Gini coefficient for the matching between agricultural water consumption and cultivated land resources is 0.005 6.Guanshan forestry center has the highest water-land resource matching coefficient of 2.08,while Shangxi township has the lowest value of 0.51.The matching coefficients of most other townships vary from 0.51 to 0.58,indicating a relatively balanced spatial distribution of agricultural land and water resources.The average irrigation area coverage rate is 26.70%,and the average storage-replenishment index is 0.46.Analysis of local water resource conditions reveals that local reservoirs and mountain ponds have insufficient water storage capacity with limited role in agricultural irrigation.It is recommended to scientifically and rationally plan the allocation of water-land resource to improve the irrigation efficiency.
