摘　　要：利用松山湖科技产业园建园前(2002年)和建园后(2006年)对松山湖水库两次水质监测结果,结合统计数据和卫星遥感数据,探讨松山湖科技产业园的土地利用快速变化对松山湖水库水质的影响,分析水质变化的原因,并提出预防水质恶化的建议。分析表明,作为一种新型的经济发展模式和产业结构优化的典型试点,松山湖科技产业园建设过程中十分注重环境保护与生态建设,但2006年的水质监测结果仍未达到地表水Ⅲ类水质标准,这与园区污水处理厂尚未建成以及土地利用类型的较大变化有一定关系,并指出未来的水质影响将主要来自面源污染。为使得松山湖水库达到东莞市备用饮用水源地水质要求,文中提出相应的对策措施。The data of the water quality of Songshan Reservoir before and after the Songshan Lake Sci. ＆ Tech. Industrial Park was constructed, respectively, in 2002 and in 2006 are analysed, the current status of its water circumstances was evaluated. Land use change in 2002 and 2006 is analyzed with the data of Landsat TM images. The results indicate that the vegetation cover proportion reduced and urban land use proportion increased around Songshan reservoir from 2002 to 2006. The water quality of the Songshan Lake didn＇t attain the Ⅲ-class water quality standard. It is found that non-point source pollution caused by land use change was the main factor to affect the water quality of Songshan reservoir. In order to improve the water quality, some measures are suggested： sewage treatment plants should be built as soon as possible; importance be attached to the study of non-point source pollutant and construction of wetland engineering; wastewater pipeline system around the reservoir be set up; ecological engineering of preventing water eutrophication be conducted; an ecological security forecasting system be established.
