It has long been thought that bears the endless ocean resources and capabilities disorderly people, excessive, gratuitous use of marine resources, the marine ecosystem destruction. Establish the correct values ??of the environment has become the need of the development of the times, increasingly received wide attention. Therefore, this article based on an overview of related fields, construction of coastal power plant engineering analysis of the impact on the marine ecological value of research to establish the value of the marine ecosystem of coastal power loss evaluation index system, and Dongying in Shandong Datang Power Plant Project The example application. Main content of this paper are: an overview of the research progress of the marine ecological value; fetch (row) outlet construction, thermal discharge, entrainment effect, residual chlorine angle, describes the value of coastal power plant on the marine ecology impact, including the value of marine living resources and marine ecosystem services function value, and its assessment methods are described in detail. Theory on the basis of assessment of marine ecological value, through the construction of coastal power of marine ecological value, starting from the point of view of the resource environmental economics, to establish the value of marine ecological damage assessment index system. Service functions into two categories, including marine living resources and marine ecosystems and living marine resources indicators divided into swimming creatures, fish eggs and larvae of benthic organisms, intertidal zone, rare and endangered aquatic organisms, plankton, fisheries production, a total of seven indicators; functional indicators of marine ecosystem services, including food production, raw materials production, recreation, provide oxygen, climate regulation, waste treatment, primary production, biological control, disturbance regulation, nutrient cycling, cultural uses, scientific value, providing gene resources, material and maintaining the diversity of 14 assessment indicators. Marine ecological value of coastal power plants will be established damage assessment index system used in Dongying in Shandong Datang Power Plant Project, an analytical assessment of the loss in value of the marine ecosystem. (1) the use of market value method to estimate Dongying in Shandong Datang Power Plant construction projects for the loss of value of the living marine resources of 1.64 million, mainly referring to the occupation of fishing waters of marine biological resources damage; market value method, shadow engineering, Robert Costanza et al. the research contingent valuation method, a variety of assessment methods to assess the power plant construction on the marine ecosystem service function value losses, including food production, climate regulation and oxygen, nutrient cycling, including substance Diversity maintain marine ecosystem service functions The loss of value of 3.3224 million yuan. It can be seen, due to the construction of the power plant program, the use of the tunnel, short ditches the intake sea water programs, thus greatly reducing the area of ??land reclamation, thereby reducing the effects on marine ecosystems impact. ② using the market value method to estimate the Shandong the Datang Dongying power plants take drainage engineering value of the loss of the living marine resources of 47.9129 million yuan, mainly referring to the diffusion of thermal discharge within the marine biological resources damage, and loss of entrainment effect on marine life calculations. Which entrainment effect caused by the loss of marine biological resources, the total economic value of 45.7548 million yuan, the total economic value of the loss of living marine resources caused by the thermal discharge of 2.1581 million yuan loss in value brought about by the effects of entrainment, thermal discharge The impact of the second. In marine engineering, power plant operation period its thermal discharge emissions, the special nature of the entrainment effect, a relatively large proportion of the value of marine ecological damage. ③ by the loss of the value of the marine ecosystem assessment calculations, mainly to economic compensation and discharge plan compensation measures.
