| 英文摘要 | 基于gIS和rS技术,应用经验模型探讨沿海港湾区域陆源污染物计算方法,旨在定量估算沿海港湾区域陆源污染物的来源、贡献,为区域环境规划与管理提供依据。该方法首先采用gIS技术划分汇水区边界和汇水单元,然后利用rS技术解译获得区域的土地利用/覆被变化,并进一步利用经验模型SCS-Cn、uSlE和污染物流失方程、排污系数法来进行陆源污染物负荷估算。以罗源湾为例,研究结果表明,基于gIS技术,以汇水区为单元对港湾区域陆源污染物来源贡献的计算方法可有效地辅助区域的环境规划与管理。; An approach to estimate the land-based pollution loads in a bay region by the integration of Geographic Information System(GIS),Remote Sensing(RS) technology,empirical models and discharge coefficient was proposed.In this approach,the sub-catchments were firstly delineated by GIS,and then land use and cover change in the study area was obtained by RS.Furthermore,the SCS-CN,USLE model,the Pollutant Loss Equation and pollutant discharge coefficient were coupled to estimate the land-based pollution loads.Luoyuan Bay was further taken as a case study to illustrate this approach.It shows that such approach is an effective means to estimate the land-based pollution loads,and it is beneficial to gain knowledge for the environmental plan and management.; 福建省青年人才项目(2007F3093) |
