河口景观生态湿地需水量探讨

摘要：河口湿地是一个新生的湿地系统，它具有生物多样性、海陆过渡性、新生性及生态脆弱性等特点。本论文总结了河口湿地的特点，提出河口景观生态湿地需水量的概念及组成要素：自身存在需水量及日常补水量； 分析河口湿地需水量的经典计算方法，然后根据相关指标标准和相应级别对湿地植物需水量、湿地土壤需水量、生物栖息地需水量和补水需水量进行重点探讨。最后提出建立河口景观湿地绿色旅游的意义是让游客在认识湿地的同时，提高湿地生态环保意识。

Study on landscape water requirement for Estuarine wetlands

Abstract: The estuarine wetlands are an emerging system of wetlands, it has a biological diversity, sea-land transition, newborn sex and ecological fragility and so on. This article summarizes the characteristics of the estuarine wetlands. proposed estuarine wetland landscape ecological water requirement of the concepts and key elements. This paper presents the basic concepts of wetland landscape of water demand and its classification. Based on the ecological and environmental functions such as water amount balance ,water quality maintenance and its improvement that wetlands perform, in this paper we analyze the classification methods of all kinds of water requirement in eco-environment aspect on wetland, especially including water requirement from wetland vegetation, soil, habitats.
