Abstract

Water security is emerging as an important and imperative issue for India. Many Indian cities are experiencing moderate to severe water shortages due to understood effects of industrialization and urbanization. These shortages would be further provoked by population stress and irrigation requirements that are major factors related to water insecurity. Around 1.2 billion people, or almost one-fifth of the world's population, live in areas of physical scarcity and 500 million people are approaching this situation. Another 1.6 billion people or almost one quarter of the world's population, are facing economic water shortage. Water use is growing at more than twice the rate of population increase in the last century. The water bodies, rivers, lakes, dams and estuaries are continuously subject to dynamic state of change with respect to the geological age and geochemical characteristics. The dynamic balance in the aquatic ecosystem is upset by human activities, resulting in pollution which is manifested dramatically as fish kill, offensive taste, odor, color, and unchecked aquatic weeds. Consequences of such human activities and discharge of sewage water makes the existence of the lakes more vulnerable. It is the prime necessary to take immediate remedial action to prevent all anthropogenic activities in the studied lakes or else the lakes will become biologically barren and will be lost forever. In the present study an attempt was made to know the physical, chemical, characteristic of lake water of selected lakes of Mysuru city.
迈苏尔市比较湖沼学研究
对印度来说,水安全正成为一个重要而紧迫的问题。由于工业化和城市化的影响,许多印度城市正在经历中度到严重的水资源短缺。人口压力和灌溉需求是与水不安全有关的主要因素,将进一步加剧这些短缺。约有12亿人,即世界人口的近五分之一,生活在物质匮乏的地区,有5亿人正在接近这一状况。另有16亿人(几乎占世界人口的四分之一)正面临经济缺水。在上个世纪,用水量的增长速度是人口增长速度的两倍多。水体、河流、湖泊、水坝和河口在地质时代和地球化学特征方面不断处于动态变化状态。人类活动破坏了水生生态系统的动态平衡,造成了污染,主要表现为鱼类死亡、难闻的味道、难闻的气味、难闻的颜色以及水草泛滥。这种人类活动和污水排放的后果使湖泊的存在更加脆弱。当务之急是立即采取补救行动,防止所研究湖泊的一切人为活动,否则这些湖泊将变得生物贫瘠,并将永远消失。在本研究中,我们试图了解迈苏尔市所选湖泊的湖水的物理、化学特征。
