基于GIS的长海海域环境信息分析
Analysis on Marine Environmental Information of Changhai Sea Area Based on GIS
摘要
Abstract
The marine environmental quality in Changhai sea area was analyzed by GIS in combination with the comprehensive evaluation of wa-ter quality and eutrophication evaluation model based on the data of water quality.The results showed as followed:the spatial distribution of pH and dissolved oxygen in Changhai sea area was fairly uniform,and most of the sea areas met the standards of first-class seawater quality;petrole-um concentration was low;the chemical oxygen demand,dissolved inorganic phosphorous and dissolved inorganic nitrogen were similar in spatial distribution;the concentration between the islands and the neighborthhood of islands was higher while the concentration was low in the open sea, perhaps it was mainly influenced by the farming activities and water exchange;the water quality in Changhai sea area was in good condition as a whole;there was no eutrophication in most areas,and only mild eutrophication occurred in the areas close to Guanglu Island, Dachangshan Is-land,Wumang Island and Haiyang Islands.关键词
