针对我国水资源保护面临的现实，借鉴在国外的研究经验，提出地下水保护的水源地保护带划分的概念，将地表补给区划分为“三带”，对“三带”划分的原则、理论依据和技术方法给出了较详细的说明，认为“三带”的划分和５０天线的确定要充分依据地下水的动力学特征、细菌在地下水中的消减规律和地下水覆盖层的性质来确定，地下水的动态特征、赋存形式和不同岩石的保护程度指数Ｉ影响５０天线的范围。在确定保护带的基础上，要加大环境保护的执法力度，针对不同保护带提出明确的环境标准和技术规范，在这方面，我国在环境科学技术上还是薄弱的，应予加强技术研究和示范，逐步建立适合我国特色的技术标准体系。
Aiming at the reality of water resources protection in our country and using the research experience in other countries for reference, this paper puts forward the concept of the division of water source protection zones of groundwater protection, divides the surface supply area into “three belts” and divides the “three belts” And technical methods are given in more detail that the “three belts” and 50 to determine the division of the antenna should be fully based on the kinetic characteristics of groundwater, bacteria in groundwater in the law of the depletion and the nature of groundwater cover to determine the groundwater Dynamic characteristics, forms of occurrence and degree of protection of different rocks Index I affect the range of 50 antennas. On the basis of the identification of protective belts, we should intensify the enforcement of environmental protection and put forward specific environmental standards and technical specifications for different protective belts. In this regard, China is still weak in environmental science and technology and should strengthen its technical research and Demonstration, and gradually establish a technology standard system suited to China’s characteristics.
