中文摘要: 湖泊是陆地水圈的重要组成部分,对地区的经济发展、气候和生态平衡起着重要的作用。湖泊藻华发生是目前全世界共同面临的重大环境问题之一。蒙古高原湖泊众多,随着人口增长、工农业的快速发展,近几年开始出现藻华现象,其中最为严重的是乌梁素海。乌梁素海是世界同纬度最大淡水湖、自从2008年开始连年暴发藻华现象,称为黄苔藻华,不仅影响生态环境系统,而且对人们的饮水、旅游、生产和生活造成极大的威胁。 本项目以内蒙古乌梁素海为研究区,研究黄苔藻华水体光学性质及其机制,发展黄苔藻华遥感判别方法,探索黄苔藻华暴发前兆。本项目的研究可为揭示黄苔暴发的时空分布特征与机理提供技术支撑,对于蒙古高原湖泊水体环境监测与保护具有重要的现实意义。

英文摘要: Inland lakes are the important part of the Terrestrial hydrosphere, and play significant roles on the regional economic development, climate and ecological balance. Lake algae bloom has become one of the world's major environmental problems. The algae bloom phenomenon has begun to appear in the Mongolian Plateau lakes in recent years with the growth of population and rapid development of industry and agriculture especially in the WuliangsuHai Lake. The WuliangsuHai Lake has appeared algae bloom from 2008 called Huang Tai. It not only cause widespread ecological system damage, but also pose a serious threat to drinking, tourism, production and human live. The optical properties and remote sensing monitoring research of algal bloom will be carried out in the WuliangsuHai Lake. The Huang Tai algae bloom identification method will be constructed in this project, and the discussion of the early warning of Huang Tai bloom will also be carried out. Successful implementation of this project will offer technical support to revealing the mechanism of spatial and temporal pattern of Huang Tai algae bloom. At the same time, the project will have an important significance on monitoring and protection of the Mongolian Plateau lakes environment.
