The marine environment provides rich and varied resources and services or functions for human’s produc-tion and life. Many countries have competitively exploited and utilized sea and ocean to develop marine economy for someyears. The over-exploitation of marine environment and the overuse of marine resources have led to resource degradation,environmental pollution and ecosystem destruction. Considering the depletion of coastal environmental resources dur-ing planning, governing and decision-making is an important measure to promote the harmonious and sustainabledevelopment of coastal environmental resources and social economy, the main precondition of which is that the depletionof coastal environmental resources by human activities has been monetarily evaluated. Firstly, this paper summarizesrelevant references in this field and analyzes different sorts of depletion of coastal environmental resources caused byhuman activities and the necessity and importance of the monetary evaluation. Finally, this paper extensively discussesthe corresponding evaluation models of the depletion of marine mineral resources, marine organism resources, mari-time transport resources, intertidal zones and shallow seas, and marine environmental functions and services includingenvironmental capacity, gas regulation, disturbance prevention, recreation and biodiversity. 展开更多

Poland is one of the countries with the poorest water resources in Europe due to its natural conditions and human impact. As a result of land reclamation carried out over decades, many elements of its hydrographic system have been changed, and some of them, like lakes, have disappeared altogether. In the days of the socio-economic transformation and more frequent extreme events, what seems worth considering is the renaturalisation of non-existing lakes, an idea presented in this paper on a selected example. 展开更多
