- 摘要:
- 从降雨量、径流量、水库面积、植被覆盖和土地利用5个方面对密云水库水源地水土资源进行调查分析，年降雨量和入库径流量有波动，但长系列分析有下降趋势，而近几年有所增加。利用北京一号小卫星和Landsat-7卫星的三期遥感影像对密云水库水面轮廓进行提取，从1992-2006年水库水面明显减少，减少区域主要分布在水库东北角的潮河入库处和潮白两河入库的中间带。用像元二分模型对密云县植被覆盖进行分析，结果表明从1992-2006年植被覆盖面积先减小后增加，其中高覆盖率区减小，中低覆盖率区面积增加。从土地利用变化分析耕地连续减少，主要变成了建设用地和林地，建设用地包括居民住地和工矿用地持续增加。
- Abstract:
- Miyun reservoir is investigated from five aspects,such as rainfall,runoff,reservoir area,vegetation coverage and land use.Annual rainfall and runoff into reservoir have decreased in past long term and increased in recent years.Reservoir area obtained from remote sensing date decreased continually in the north-east of reservoir and middle zone between Chao river and Bai river infall.Vegetation coverage is analyzed with two-division pixel model and results show that total vegetation coverage area decreased at first phase and increase recently.Land use changes reflect that soil and water conservation policy,population and economic development together promote cultivated land decrease while construction land and forest land increase.
