摘要

河流和洪泛区具有水文和生态上的密切联系而构成一个统一的环境整体

由此提出了河流—洪泛区环境系统的概念

并从整体性、异质性、开放性、复杂性、脆弱性等方面对其特征进行了分析研究。洪泛作用对于河流—洪泛区环境系统整体性的维系起着重要作用

环境系统的异质性体现在空间尺度上的异质性和时间尺度上的异质性2个方面

环境系统具有开放性

在自然因素和人类活动的双重影响下

环境系统呈现出复杂性和脆弱性。

Abstract

River and floodplain compose a whole environmental system as they have hydrological and ecological connection

and thus a scientific concept of river-floodplain environmental systyem is established and analysed.The main characteristics of river-floodplain environmental system include the followings: wholeness maintained by flooding

spatial and temporal heterogeneity

openness

complexity and fragility.Flooding plays key roles in maintaining wholeness of the river-floodplain environmental system

and the system responds to process and functions of flooding.The river-floodplain system is enfluenced by both natural process and human activities.
