Study On The Eco-compatibility Between Coastal Wetland Nature Reserve And Port Construction

The Shipping development promoted large-scale port construction, especially on the edge of Coastal Wetland Nature Reserve. What kind of impact the port construction will bring on the Coastal Wetland Nature Reserve, and how to balance economic development and ecological protection when using wetland, so as to create the biggest economic value and not hurt "wetland", are deserved scholar to concern.This paper constructs an eco-compatibility evaluation model between Coastal Wetland Nature Reserve and port construction. The target layer is eco-compatibility between Coastal Wetland Nature Reserve and port construction, in which six aspects are included as following: external pressure, ecological service functions, landscape assessment, ecological health, regional carrying capacity evaluation and ecological system risk evaluation, and 17 middle layer indicators,51 bottom layer indicators; The paper also gives the judgment standard of eco-compatibility. The eco-compatibility model, proposed by this paper, after adjusting the index can also be applied to analysis eco-compatibility between other environmental areas and construction projects.Based on eco-compatibility evaluation model, combined with the judgment standard, using the analytic hierarchy process (AHP) to analysis the weight, chooses a non-polluted cargo port as an example to assign each indicators and calculate the eco-compatibility value; Choosing the Yalu River Coastal Wetland Nature Reserve as a research area, by the use of catastrophe theory evaluation method and the corresponding data collection of research year, it is concluded that the eco-compatibility of research year between the study area and Dandong Port which is already exist, and gives an assessment of the influence degree on the study area from the construction and operation of Dandong Port.
