摘要
水文情势变化能直接影响湿地的非生物环境特征及生物环境特征,进而影响到湿地生态系统整体特征,而湿地水源是否稳定又决定了湿地环境能否良性发展。本文选取拉鲁湿地作为研究对象,着重从生物环境特征方面分析拉鲁湿地水文情势变化的生态环境效应。结果表明,近年来,拉鲁湿地演替方向趋于沼泽化湿地→沼泽化草甸→草甸→荒漠。
Changeg in the hydrological regime directly affect wetlands abiotic environmental, characteristics, biologcalchal＇acteristics of wetlands, and then affecting the overall characteristics of the wetland＇ ecosystem. Wetland environment＇s benign development depends on the stability of the wetland water. This article sel.eets the Lalu wetland as a research object,From biological environment characteristics aspecta analyze ecological environment effects with Lalu wetland hydrological change. The results show that In recent years Lalu wetland succession direction tends to swamping wetland, swamping meadow, meadow and desert.
