摘要
湍河是汉江流域上游的一条主要河流。随着南水北调中线工程的实施,该地区成为名副其实的“地下水库”。近年来随着人类活动的加强,人为因素在湿地生态演变过程中的干预越来越明显。本文从草地生态角度分析了湍河湿地生态现状和影响因素。研究表明,湍河湿地生态整体上好转,局部出现退化情况。在此基础上初步提出了防止局部生态恶化的综合治理对策。
Tuan River is a main branch of Han River in its upstream.With the implementation of the South-to-North Water Transfer Project, the groundwater in the area really becomes the ＂Underground Reservoir＂ .In the past few years for the intensification of the human activities, the factor of human beings interference becomes more and more dominant in the transformation of the wetland ecosystem. In this paper, the author takes the grassland ecology as a model, and analyzes the present condition of wetland ecology and the factor whichaffects it. According to the research, the author shows that Tuan River wetland ecology has bettered in the whole, though deteriorated locally, and puts forward comprehensive countermeasures to curb the local deterioration.
