遥感监测的黄河三角洲平原水库及水产养殖场面积变化

Surveying area changes of plain reservoirs and aquafarms in the Yellow River Delta with remote sensing data

利用不同时相(间隔约5 a)的遥感影像分析了黄河三角洲平原水库和水产养殖场面积的变化。结果表明,20世纪70年代后期与80年代初期,黄河三角洲平原水库和水产养殖场面积增长缓慢,自80年代后期增长迅速,按照其与年份的线性回归方程计算,黄河三角洲平原水库和水产养殖面积在2005年和2010年分别将达到352 km2和418 km2,其结果可为黄河三角洲的治理和开发提供参考。

Area changes of plain reservoirs and aquafarrns in the Yellow River Delta with remote sensing （RS） data and geographic information system（GIS）are presented in this paper. Results indicate that the areas of reservoirs and aquafarms in the Yellow River Delta are very small in 1976, and they increased very slowly until the year of 1981. From the year of 1986, they increased very quickly. According to the regression analysis between areas and years, areas of plain reservoirs and aquafarms in the Yellow River Delta in the year of 2005 and 2010 will be 352 km^2 and 418 km^2 respectively. These results can help to give decision-makers some evidence for management of the Yellow River Delta.
