加拿大科协以“21世纪水的继续利用”为题,提出了专门报告。报告指出:“水对于加拿大的过去、现在和将来,都有极重要的意义”。从1986年开始的这项研究的目的是,把水资源问题作为一项重要而关系全局的问题提出来,讨论水资源管理中的科技作用问题,以及近20年乃至30年时间在水资源研究、管理方面政策的制定。这项研究提出在近期和将来水科学领域有以下四项研究课题:1.从大气到水态、酸性、毒性物质的迁移,以及它对水圈的影响;2.地球变暖及其对水供应的影响;3.以废弃物处理场为源的毒性化合物向地下
Canadian Association for Science and Technology to “21st century water continues to use ” for the title, made a special report. The report states: “Water is of great importance to Canada’s past, present and future.” The purpose of this study, beginning in 1986, was to bring water issues as an important and inter-related issue to discuss the role of science and technology in water resources management and the role of water resources in water resources research in the last 20 or even 30 years Management policy formulation. This study proposes the following four research topics in the field of water science in the near and future: 1. The migration from the atmosphere to the water, the acidic and toxic substances, and its impact on the hydrosphere; 2. Global warming and its effect on water Supply impacts; 3. Toxic chemicals from the waste disposal site to the ground floor
