南方丘陵红壤区抽水蓄能电站建设的生态环境影响及对策研究

基于浙江省丘陵红壤区的乌龙山抽水蓄能电站建设工程实例，利用2004年SPOT卫星遥影像为基本信息源，采用现场调查、样方调查、收集资料、卫片及航片的解析等方法，通过ARCVIEW软件技术获得工程建设前后工程建设区土地利用变化图及植被分布图。选用土地利用、植被、生态完整性为评价因子，分析预测工程建设过程和实施强度对区域生态环境可能产生的影响。结果显示这种影响使土地利用类型增加，各类型的面积有所改变；植被类型基本没有发生变化，面积减少，生物量和生产力值也有所降低，但这种影响基本不会改变评价区原本的生态完整性，生态系统仍然具有完整的结构和连续不断的运行过程。

Effect and Countermeasures of Pumped Storage Power Project on Regional Eco-Environment in Hills Red Soil Region of Southern China

This research is based on the Wulong mountain pumped storage power project in Hills red soil region of Zhejiang province.First the land-use maps and vegetation maps before and after the construction are generated with ARCVEW software,by using the SPOT images in 2004 as the basic information sources,the project initial design as the bases,and by ways of material collection,field work,quadrat investigation and analysis of satellite and aero images.With these maps,three evaluation factors(land-use,vegetation and eco-integrity) are chosen to analyze the potential effect of the construction on the ecological environment.The result shows that the effect brings certain impact on land-use and vegetation of the area(namely,an increase in land-use types,a slight change in the area of each type,no change in vegetation types,and adecrease in vegetation area,biomass and productivity value).Yet the environmental effect of the project will not essentially alter the original eco-integrity of the evaluated area.The eco-system remains its complete structure and consistent operating process.
