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.

本研究旨在整合已有的深入研究流域环境的水文分析方法，以期为实际的流域环境管理做出贡献。(1)流域水文过程及其模拟研究(2)流域水循环及其影响评价(3)水污染过程与土壤侵蚀过程分析与评价(4)流域水环境评价(5)流域尺度用水管理系统评价在(2)中，研究了一种量化流域保留容量的方法，以此作为反映流域水文循环合理性的一个指标。(3)对农用地水污染与净化过程、径流过程中酸沉淀物行为、土壤侵蚀机理和水库淤积过程的分析方法进行了讨论和评价。(4)尝试从水文学角度对滨水环境进行评价。在(5)中，讨论了大型灌溉系统用水管理的算法，研究了流域规模用水方案的分析与评价方法，这些结果被认为是为集成提供了充分的基础，尽管它们的具体集成思想还不完善。在本研究提供的资料的基础上，对这一领域进行进一步的研究，将会带来更完整的整合。
