首发时间:2009-11-02
摘要:该文利用ERDAS软件对白龙江干流沙川坝~苗家坝河段的遥感图和土地利用图进行解译校正。同时对该流域的植被样方和生物量进行了调查,并利用GIS软件对其进行了有效地分析。结果表明:由于工程建设的影响,研究区的生态环境变化明显,整个规划评价区的生物量毁损总量湿重为2591吨,折算为干重为1555吨;工程建设毁损植株总量为39858.18万株。

Impacts of Step Hydropower Development on Ecological Environment in Bailong River Shachuanba~Miaojiaba
Abstract:This paper utilizes ERDAS software to interpret and correct RS image and landuse image of Bailong River, with investigation of vegetation and biomass and spatial analysis using module of GIS. The results show that ecology environment has seriously changes which are affected by engineering construction. The biologic loss of the total area of interest is about 2591 tons in wet weight which convert into dry wet is about 1555tons. The plant number destroyed by engineering construction is about 398.5818 million.
Keywords: step hydropower ecology environment biologic amount
