"Creation of a Hydrological Cycle System of the 21 st Century and Preservation of the Aqueous Environmet" in the Arekawa River [1] Examination for the Creation of a Viable "Hydrologica] Cycle System" in the Arakawa River For the preservation of the hydrological cycle and the the water source forests on the headwaters of the Arakawa River, (1)It is necessary to cultivate water source forests. (2)lt is necessary to step up efforts to create, maintain and manage water source forests. (3)In light of the importance of creation of a "hydrological cycle system "(including "Green Dam" Project), an examination for the preservation of the natural environmentn in the upper reaches of tha Arakawa River was made. [2] Examination for the Creaton and Preservation of Sourcer of City Water in the City of Tokyo (1)The Tokyo Metropolitan Govemment Office manages city water source forests on the Tama River with emphasis on [mizuhi] in the upper reaches of the river It has been verified that the water of t … More he river is of good quality. (2)For the preservation of the headwater for city water supply of the Arakawa River and Tone River ,it is necessary to take appropriate river water purification measures, [3] Examination for the Creation of a Sewage Treatment System in the Upper Reaches of, the Intermontane Aiaes on, the Arakawa River (1)It has been found that as a result of widespread use of combined sptic tanks in the uppei reaches of, and the intermontane areas on, the Arakawa River, the quality of water in terms of BOD in these areas can be reduced to less than one-eight of the Current level (2)In viewnof the fact that sewage/industrial waste theatment plants are concentrated in the middle reaches of the Aiakawa River, establishment of an emission standard applicable to the river and administrative guidance on such a standard by the national government aie essential.[4] Adoption of an"Aqueous Environment Protection Sysytem"Proposed by Residents of the Local Community When residents of the local community or a private environmental protection groups makes public the results of a survey of the fluvial environment, it is necessarly to give serious consideration to them and create a relevant system which clearly reflects them at theadmmistrative level.

“建立21世纪的水文循环系统和保护水环境”，载于阿雷卡瓦河[1]为保护荒川河的水文循环和水源林，(1)有必要培育水源林。(2)加强水源林的营造、维护和管理。(3)考虑到建立“水文循环系统”(包括“绿坝”项目)的重要性，对荒川河上游的自然环境保护进行了审查。[2]东京市水源地的创建与保护(1)东京都政府厅管理多摩河边的城市水源林，重点是该河上游的[Mizuhi]。经核实，t…的水此外，这条河的水质很好。(2)为了保护荒川河和托尼河的城市供水水源，必须采取适当的河水净化措施，[3]在荒川河上游山间地带建立污水处理系统的审查(1)发现，由于荒川河上游和山间地区广泛使用组合式SPTIC水箱，考虑到污水/工业废物处理厂集中在Aiakawa河中游的事实，这些地区的BOD水质可以降至目前水平的八分之一以下，建立适用于这条河的排放标准，并由国家政府对此标准进行行政指导是必要的。[4]当当地社区或私人环保团体的居民公布河流环境调查结果时，采用当地社区居民提出的“水环境保护系统”，有必要认真考虑这些问题，并建立一个相关的制度，在行政层面上清楚地反映这些问题。较少
