伶仃洋N,P静态环境容量的研究

本文利用陆地卫星影象具有水陆边界清晰和多时相等优点,计算出伶仃洋枯、平、丰水期的水容量。结合实地采样分析,推算出伶仃洋从上界各口门排入的N,P输送量,和从伶仃洋输出南海的N,P通量;估算出伶仃洋的N,P静态容量,为伶仃洋水环境的治理和资源开发利用的环境保护规划提供了科学依据。

STATIC ENVIRONMENTAL CAPACITY APPROACH OF N, P IN LINGDINGYANG ESTUARY

Water capacity in low median, and high water periods was calculated by using Landsat images with distinctive water and land boundary and multi-phases, N, P transport amount discharged in Lingdingyang from upper river mouths, N, P flux from Lingdingyang to Nan-hai and static environmental capacity of N, P in Lingdingyang were also estimated in this paper providing a scientific basis for environmental conservation planning in the treatment of water environment and the development of resources in Lingdingyang.
