摘要：随着我过社会人口的增加和我国经济的飞速发展，极大的提高了我国的综合国力和世界竞争力。于此同时，在工业化发展迅速和城市化进程加速的时代，很多城市饮用水水源地周围环境遭到破坏，水源地水质也逐步下降.所以，我们在发展的过程中也必须充分意识到保护水源地水质安全的必要性，也得充分意识到水源地水质评价的重要性。论文通过运用与环境科学的现代理念和现代的技术手段，进行了城市饮用水水源地安全评价体系的研究并取得了较理想的研究成果。主要通过分析倒天河水库的基本情况，计算相关水环境指标和管理环境的指标开展评价水源地的水质状况和环境管理状况的工作。7124

Evaluation of the environmental condition of centralized drinking water source in a certain district
Abstract：With the rapid development of our society and the increase of the population of our country's economy, greatly enhance China's comprehensive national strength and international competitiveness. At the same time, the rapid development of industrialization and city accelerated process of age, drinking water pollution has become an urgent problem to be solved. A lot of city drinking water sources around the destruction of the environment, water quality is gradually reduced, which seriously affect the sustainable development of the health of the masses and the local economy. So, we must also be in the process of development, fully aware of the need to protect the source water security, also fully aware of the importance of water quality assessment of water source. The paper by using modern ideas and environmental science and modern technology, the safety evaluation system of city drinking water source, research results have been achieved ideal.
Key Words：Centralized water supply; environmental assessment; water quality assessment
