湖泊生态系统的结构与功能——湖泊恢复与管理基础浅析

湖泊是一个复杂的动态的生态系统，其恢复与管理是一个十分复杂的系统工程。不同流域系统结构导致了湖泊特性的极大差异；湖泊水体中水的滞留、水量平衡、入湖溶解性物质、颗粒沉积物、湖水深浅、湖水的流动、分层与混合、水生植物的光合与呼吸作用、群落演替、沉积物的沉积与分解、水生生物食物网等系统内能流、物流结构的循环功能，对湖泊演化会带来有利或不利的影响；湖泊通常营养状态的单向性系列演替受人为干扰程度有很大的差异。

Structure and Functieon of Lake Ecological System

Lake is a complicated,dynamic ecological system,the resumption and management of which is a complex systematic project.The distinct basin system structure results in the huge characteristic differences of lakes.The Lag and the balance of water,solutive materials entering into lake,particle sediment in the lake water,the depth,moving layering and mixing of the lake,the photosynthesis respiration,community succession of the aquatic plants,the depositing and dissolving of the sediments and the food net of these energy current and object accuracy will bring about favorable or unfavoralbe,result to the succession.The unidirectional serial succession of genneral nutrition state of lake has great difference as to the human interference.
