The Study On The Eco-environment Current Status And Ecological Protective Function In Hebei Coastal Zone

The ocean is the important base of human kind sustainable development. At present, the reasonable exploitation of sea resources is the extremely reliable way of resolving difficult problems faced by the human society, such as population expansion and resources shortage. However, the coastal eco-environment has been destroyed to some extent, for the man's intensive and improper way of exploitation. This has greatly weakened the human society's ability of sustainable development. People have gradually focused on the eco-environmental problems closely.At present, besides marine function zoning theory, there are not many theories and research results about eco-environmental protection in coastal zone. The research on ecosystem service in coastal zone, the basic theory about eco-environmental protection in the coastal zone, begins in recent years. And it is still at the stage of exploring. Based on the systematic analysis of research results in this field, the thesis assesses the eco-environment in Hebei coastal zone, especially the current status of seashore water quality for the first time; and the thesis assesses the importance of protective function in the coastal zone; at last the thesis proposes the management countermeasure.The main body of the thesis can be divided into four parts.In the first part, after analyzing the necessity and importance of eco-environmental protection in coastal zone and commenting this field theories about eco-environmental in coastal zone, the thesis proposes the purpose and the innovations of the thesis.In the second part, the thesis seeks to study the eco-environment in coastal zone from the along sea water quality and the factors of ecosystem. Firstly, the thesis assesses the along sea water quality by analyzing the accurate water quality monitoring data of along sea and the rivers flowing into the sea. Secondly, the thesis...
