项目摘要

The present research is aimed at intergrating existing methods of hydrologic analyzes deeply involved in watershed environment for contribution to practical watershed environmental management. The research was conducted in the following five fields, in each of which previous researches were reviewed and new achievement for the integration was discussed.(1) Analyzes of watershed hydrologic processes and their modeling(2)Evaluationof watershed water circulation and impacts on it(3) Analyzes and evaluation of water pollution processes and soil erosion processes(4) Evaluation of watershed water environment(5) Evaluation of watershed-scale water use management systemsIn the (1), a method of modeling evapotranspiration mechanism was discussed and channel routing methods were evaluated. In the (2), a method of quantifying watershed's retention capacity as an index to present soundness of the hydrologic cycle of the watershed was examined. The results of the (3) included discussion and evaluation of analysis methods on water pollution and purification processes in agricultural land, behaviors of acid precipitates in runoff processes, soil erosion mechanism and siltation processes in reservoirs. In the (4), evaluation of waterside environment from hydrologic point of view was tried. In the (5), algorithm for water management of large-scale irrigation schemes was discussed and a method for analysis and evaluation of watershed-scale water use schemes was examined.These results are considered to provide a sufficient basis for the integration, though the concrete idea of the integration of them is still incomplete. The further study in this line based on the materials provided by this research will lead more complete integration.

本研究旨在整合深入涉及流域环境的现有水文分析方法，为实际的流域环境管理做出贡献。研究工作在以下五个领域进行，分别回顾了前人的研究成果，并讨论了整合的新成果。（1）流域水文过程分析及其建模（2）流域水循环及其影响评价（ 3）水污染过程和土壤侵蚀过程分析与评价（4）流域水环境评价（5）流域规模用水管理系统评价（1）讨论了蒸散机制建模方法和渠道演算方法是评价。在(2)中，研究了量化流域滞留能力的方法，作为表示流域水文循环健全性的指标。 (3)的成果包括农用地水污染与净化过程、径流过程中酸沉淀物行为、水土流失机制和水库淤积过程等分析方法的讨论和评价。 (4)尝试从水文角度评价滨水环境。在(5)中，讨论了大型灌溉方案的水管理算法，并检验了流域规模用水方案的分析和评估方法。这些结果被认为为集成提供了充分的基础，尽管它们整合的具体想法仍然不完整。基于本研究提供的材料的进一步研究将导致更完整的集成。
