摘要:

探究农业水贫困与粮食生产脆弱性耦合协调规律,对水资源短缺和粮食生产能力较差的汾河流域具有重要意义。通过构建农业水贫困与粮食生产脆弱性评价指标体系,测算了2007—2021年汾河流域农业水贫困与粮食生产脆弱性耦合协调度,查明了二者耦合协调时空格局及影响因素。结果表明:(1)研究期内汾河流域农业水贫困显著缓解,水贫困指数由0.349上升到0.384。上游区农业水贫困最严重(0.334),中游区次之(0.356),下游区较好(0.385);西部区水贫困现象较东部区严重。(2)研究期内汾河流域粮食生产脆弱性无明显差异。上游区粮食生产脆弱性现象严重(0.348),中游区次之(0.379),下游区较好(0.419)。(3)研究期内汾河流域农业水贫困和粮食生产脆弱性耦合协调度无明显变化。耦合协调度总体上呈现北低南高为主、西低东高为辅的空间分布特征。(4)影响汾河流域农业水贫困和粮食生产脆弱性耦合协调度的主导因子依次为单位粮食播种面积用水量、粮食生产农药施用强度、粮食生产机械化水平、粮食作物播种面积占比等,且因子两两交互有增强的效果。

Abstract:

Exploring the coupling and coordination laws between agricultural water poverty and food production vulnerability is of great significance for the Fenhe River basin, which faces water shortages and poor grain production capacity. This study constructed evaluation index systems for agricultural water poverty and food production vulnerability in the Fenhe River basin. It calculated the coupling coordination degree between the two from 2007 to 2021 and identified the spatial-temporal patterns and influencing factors of their coupling coordination. The results showed that: (1) During the study period, agricultural water poverty in the Fenhe River basin significantly eased, with the water poverty index rising from 0.349 to 0.384. Spatially, the upstream region experienced the most severe agricultural water poverty (0.334), followed by the midstream region (0.356), and the downstream region (0.385). Additionally, the western region showed more severe water poverty than the eastern region. (2) There was no significant difference in food production vulnerability in the Fenhe River basin during the study period. Spatially, the upstream region exhibited the most severe food production vulnerability (0.348), followed by the midstream region (0.379), and the downstream region (0.419). (3) During the study period, there was no significant change in the coupling coordination degree between agricultural water poverty and food production vulnerability in the Fenhe River basin. Overall, the coupling coordination degree exhibited a spatial distribution characterized by "low in the north and high in the south", supplemented by "low in the west and high in the east". (4) The dominant factors affecting the coupling coordination degree between agricultural water poverty and vulnerability of food production in the Fenhe River basin are water consumption per unit area of grain sowing, pesticide application intensity in grain production, level of mechanization in grain production, and proportion of grain crop sowing area, etc. Additionally, there is an enhancing effect when these factors interact with each other.

Key words: agricultural water poverty, grain production vulnerability, spatial-temporal coupling, driving factors, Fenhe River basin
