In this research, we have been aiming at the development of integrated water environment management models with the function of predicting and evaluating the watershed nutrient runoff loads of nitrogen and phosphorous from urbanizing agricultural watersheds in Asian monsoon region. The distributed-parameter models have been constructed by utilizing GIS techniques together with the detailed watershed information such as DEM, land utilization, river network and point sources. The prediction accuracy has been improved by innovating artificial intelligence techniques and time-frequency analyses when modeling sub-processes of nutrient runoff loads from various sources and water quality dynamics in closed water bodies, because it is generally difficult to quantify those sub-processes accurately.The model construction and validation have been conducted at two watersheds that have entirely different watershed characteristics, the Chikugo River watershed and the Zuibaiji River watershed. The Chikugo River watershed has a largest watershed area in Kyushu Island, Japan and a huge variety of land utilization in the watershed, while the Zuibaiji River watershed is located at the west of Fukuoka City, Japan and a typical urbanizing agricultural watershed with a relatively small watershed area. The models have been constructed and validated in the watersheds by quantifying each of sub-processes and connecting sub-models with each other.

本研究旨在建立具有预测和评价亚洲季风区城市化农业流域氮磷径流负荷功能的综合水环境管理模型。利用GIS技术，结合DEM、土地利用、河网、点源等流域详细信息，构建了流域分布参数模型。在模拟不同来源的养分径流负荷子过程和封闭水体水质动态过程时，由于难以准确量化这些子过程，因此通过创新人工智能技术和时频分析提高了预测精度。在两个具有完全不同流域特征的流域，即赤果河流域和嘴白集河流域，进行了模型的构建和验证。千古河流域是日本九州岛流域面积最大的流域，流域内土地利用种类繁多，而嘴白鸡河流域位于日本福冈市西部，是典型的城市化农业流域，流域面积相对较小。通过对每个子过程进行量化，并将子模型相互连接，构建了模型并在流域中进行了验证。
