为实现河长制分级分区评价,提出行政分级和地形地貌分区相结合的矩阵化效能评价模式,从河长制的六大任务和社会公众等7个方面分别构建市县(18个指标)、乡村(16个指标)2个级别的河长制效能评价指标体系,利用层次分析法得出山丘区、平原和滨湖区2个区域不同特性的指标权重,建立二级模糊综合评价模型对江西省赣州市、南昌市、上犹县、樟树市、梅水乡和张家山街道等典型区域进行评价,评价结果分别为好、中、好、好、中、好。结果表明:在山丘区,水资源保护是影响各级河长制效能的主要因素,水生态修复影响了赣州市、上犹县效能,水污染防治影响了上犹县、梅水乡效能,而在平原和滨湖区水污染防治是影响各级河长制效能的主要因素,此外水资源保护影响了南昌市、樟树市效能,水生态修复影响了樟树市效能。结果与实际情况基本一致,表明该评价体系适用于河长制效能分级分区评价。

To evaluate the river chief system in different levels and zones, we propose a matrix-based efficiency evaluation model that combines administrative grading with terrain and geomorphic zoning. Our evaluation index system for the river chief system is constructed based on seven aspects, including the six tasks of the river chief system and public involvement. We divide the index system into two levels: city and county level (18 indicators) and town and village level (16 indicators). We employ the Analytic Hierarchy Process (AHP) to determine the index weights for different characteristics of mountain and hilly areas, as well as plain and lakeside areas, and subsequently, we establish a two-level fuzzy comprehensive evaluation model to evaluate representative regions such as Ganzhou City, Nanchang City, Shangyou County, Zhangshu County, Meishui Town, and Zhangjiashan Street in Jiangxi Province. The evaluation results for these regions are categorized as good, medium, good, good, medium, and good, respectively. Our findings indicate that in hilly areas, the efficiency of the river chief system at all levels is mainly affected by water resource protection, whereas water ecological restoration influences the effectiveness of the system in Ganzhou City and Shangyou County. Additionally, water pollution control affects the effectiveness of the system in Shangyou County and Meishui Town. On the other hand, in plain and lakeside areas, water pollution control is identified as the primary factor impacting the efficiency of the river chief system at all levels. Water resource protection affects the effectiveness of the system in Nanchang City and Zhangshu County, while water ecological restoration also influences the effect in Zhangshu County. The evaluation results align well with the actual situation, affirming the suitability of our evaluation system for grading and zoning the efficiency of the river chief system.
