Evaluation of Agricultural Water Appropriate Along the Yellow River in Shandong Province Based on Fuzzy Inference
In order to study the development situation of agricultural water-appropriate in Shandong Province along the Yellow River,a water suitability evaluation system for agriculture along the Yellow River in Shandong Province was constructed from three aspects,namely,water resources carrying capacity,level of agricultural water use,and coordina-tion between water resources and agriculture.A fuzzy reasoning evaluation model was used to quantitatively analyze the current agricultural water-appropriate status of the study area in the current year and the dynamic change of agricultural water suitability from 2013 to 2021.The direction of short-term optimal enhancement was put forward.The results show that the evaluation score of agricultural water-appropriate in the study area is 46.64,in which most of the cities are in the state of barely water suitability and mildly water suitability,and only Jinan and Binzhou are in the state of good water suitability of class Ⅱ;Water resources carrying capacity is the main constraint for the development of agricultural water-appropriate,and increasing the carrying capacity of water resources is the optimal direction for enhancing the agricultural water suitability in the study area and the cities of Jinan,Zibo,Liaocheng,Binzhou and Jining.From 2013 to 2021,the agricultural water-appropriate index shows a zigzag upward trend,and the overall agricultural water-appropriate level de-velops towards a favorable trend.
