在广泛咨询和调研的基础上,首先确定了影响农田排水资源灌溉利用适宜性的各类重要因素,包括排水水质、作物特性、土壤特性、水文气象、灌排措施等5个方面,然后根据系统性、代表性、可操作性等原则,筛选了各个准则层下面指标层的具体指标,最后构建了比较完整的农田排水资源灌溉利用适宜性评价指标体系,为进一步开展农田排水资源灌溉利用适宜性评价提供了基础。
Based on wide consulting and investigation, firstly the key factors of the suitability of drainage water for irrigation were identified, including the quality of drainage water, crop characteristics, soil properties, hydrology and meteorology, and irrigation and drainage management measures. Then according to the principles of systematieness, representative, operability and so on, the specific indexes of the index layer under each criterion layer were screened, and a relatively complete evaluation index system of the suitability of drainage water for irrigation was built, providing a foundation for further research.
