| 摘 要： | 分析近20年来珠江河口水环境变异的特征,探讨珠江河口水环境与水生物相互联系和相互作用的关系。结果表明,珠江河口形态、地貌、水文情势和入河污染物等变异改变了珠江河口水生物的栖息条件,削弱了河口生态系统的自动调节修复能力和稳定性,对河口生态系统的物质循环、能量流动和发育演化平衡构成了重大影响。

| Abstract: | The paper analyzes the variation features of water environment of the Pearl River estuary in recent 20 years and researches with the interrelation and interaction of water environment and aquatic biology of the estuary. The results indicate that the variations of morphology, geomorphy, hydrological regime and water pollutants have changed the perching conditions of aquatic living things of the estuary, decreased self regulation and restoration capability and homeostasis of ecosystem, influenced greatly on matter cycle, energy transfer, development, evolution and equilibrium in the ecosystem of the Pearl River estuary. |
