梅林水库紧邻深圳市福田中心区,库区拥有良好的自然生态环境和优良的水质。水源保护区内分布着被称为"活化石"的国家Ⅰ级保护植物仙湖苏铁。经过漫长历史的自然和人为等因素影响,梅林水库仙湖苏铁及其种群呈现明显的衰退甚至消亡迹象,直接危及水源涵养生态环境的健康。在对珍稀植物衰退原因分析的基础上提出了保护梅林水库生态资源的对策。

Meilin Reservoir is adjacent to the Shenzhen Futian district, with good natural ecological environment and excellent water quality in the reservoir area. A first-rank protected plant called Cycas fairylakea, known as living fossils, is distributed around water source protection areas. After a long history of natural and man-made factors such as the impact of Meilin Reservoir, Cycad fairylakea population shows clear signs of decline and even extinction, which endanger the health of the ecological environment of water conservation directly. Based on the analysis of declining reasons of rare plants, it gives some measures to protect the ecological resources in Meilin Reservoir.
