| 摘 要： | 基于遥感技术,对反映17 a来博贺澙湖的5景遥感影像定量反演潮滩水边线,在此基础上推算澙湖潮滩的沉积与冲刷速率,同时对引起潮滩变化的动力作用进行探讨,结果表明博贺澙湖的潮滩以淤展为主,其中处于开敞地段的澙湖潮滩出现冲刷,遮蔽岸段的澙湖潮滩淤积,控制澙湖潮滩变化的主要因子是包括圈围潮滩成盐田、虾池以及鱼塘等的人类活动.

| Abstract: | Based on the remote technique and 5 remote images, waterline of qualitative reversion during the 17 years' time span was obtained and the rate of scouring and silting of lagoon tidal-flat was also further calculated. Moreover, the dynamic actions resulted in the changes of tidal-flat in the present paper were discussed. The results showed that the main trends of the changes of tidal-flat existed were silting spreads, where the open segment occurred by scouring and the shadow zone occurred by silting. It is a key factor for human activity to control the changes of tidal flat, which showed that the mud-flat turned into salt soils, shrimp pools and fish reservoirs, etc. |
