Abstract


The ocean is a natural treasure trove of resources, has a wealth of resources, a strong material foundation for the sustainable development of human society, is also increasing with the rapid social and economic development and the rapid expansion of the population, waters subject to pressure from all sides, however, The coupled with on the people to mistakenly believe that marine resources is inexhaustible supply of, inexhaustible source of, resulting in sea area of ??resources and environment greatly waste and destruction of. In recent years, overfishing, blind development, illegal sewage repeated, sharp drop in marine resources, marine environment and other issues have become increasingly prominent parts of the ocean's assimilative capacity limit has been reached. From the waters of bearing capacity factors and the evaluation index system, to regulate marine resources development and utilization, rational allocation of marine resources, promote coastal areas of population, resources, environment and socio-economic coordinated development of scientific basis. Draw domestic and foreign resources and environment carrying capacity theory and research methods based on the concept and connotation of the waters carrying capacity defined and discussed the influencing factors and the evaluation index system, mainly from natural factors, human factors and socio-economic factors influencing factors are analyzed in detail; and the advantages and disadvantages of the existing index system based on widely recognized around the world \model was constructed the waters carrying capacity evaluation index system, and after the waters bearing capacity evaluation methods were described in detail. To illustrate that the waters carrying capacity evaluation index system created a specific waters carrying capacity to effectively assess, select the Jiaozhou Bay as the research object, and its empirical analysis. Built on the basis of expert opinion and field research in Jiaozhou Bay and the surrounding the Jiaozhou Bay carrying capacity evaluation index system, on the basis of expert opinion is sought, selected 18 representative indicators, taking into account these indicators the interaction between the data can be obtained as well as indicators, we use DEMATEL method to carry out an in-depth analysis of the indicators, derived indicators reasons, found that nine indicators causal factors, the result of factors other nine indicators, thus revealing the interaction relationship between the indicators; nine indicators of the causal factors and Analytic Hierarchy Process empowerment, and a comprehensive index method to calculate the bearing capacity of the composite index of Jiaozhou Bay. The results showed that Jiaozhou Bay belong to the non-sustainable development Level, for the results of the evaluation, to identify the the affect the Jiaozhou Bay the salient aspects of of the of sustainable development and the the existing problems, in the the are put forward in This on the basis of the of sustainable development countermeasures and suggestions in Jiaozhou Bay.
