The Study On Interaction Mechanism And Coordinated Development Of Population And Environment

The population and environment question ,which are two major challenges to the sustainable development in the world today , have played an important influence in restraining the fast and healthy development of economy and society in China.Whether the population and environment subsystems can develop harmoniously is significant and affects profoundly to our country.The implementation of scientific development concept which is humanist ,comprehensive, coordinated and sustainable privids us an rare and good opportunity to promoting the coordinated development of the populaition , the resources, the environment and the social economy. How to change the past traditional development model which develops social economy at the expense of the resources and the enveronment,and realize in the coordinated development of the populaition ,resources and enveronment is in front of our country's new duty.As China's second large population and ecnomicially strong province, the pressure of population and the environment in Shandong is especially great.For this reasion ,this thesis has made a systematic research on the interaction mechanism and the coordinated development of the population and the environment in Shandong Province ,based on the domestic and foreign research results.This thesis is divided into five parts.The first part is introduction. Beginning with the study background, meaning ,methods and the present international and national research situation,then this thesis gives analysis and comprehensive comments on related theoris of the coordinated development of the population and the environment systems.The second part is one of the key points of the thesis.This part makes resesaches on the interaction mechanism between the population and the environment from the theoretical and empirical parts, taking Shandong as example.In theoretical research,this part analyzes the interaction mechanism between the population and the environment systems in perspective of population quantity ,quality ,structure,migration and consumption level differences.In empirical research,this part analyzes the interactions between population quantity, quality, structure,migration, consumption and environment systems in Shandong Province,using qualitative and quantitative methods. The result indicates that the population subsystem and the environmet subsystem have obvious interaction ,which involves multi-factors and multi-levels.The third part is the key and difficulty points of this thesis.First the index system and coordination development model reflecting the coordinated development of the population and environment systems is designed,based on the existing research results.Then , the historical evolution of the population and environment systems from 1999 to 2005 in Shandong Province ,and the spatial differentiation of the population and environment systems in the 17 prefectures in Shandong province in 2006 are measured and analyzed.The results indicated that the coordinated development level between the populaition and enveronment systems in Shandong Province assumed the trend of escalation from1991 to 2005,and can be divided into three stages. The coordinated development between the populations and the environment systems in 17 prefectures in Shandong assumed obvious region differences ,and the coordinated development in east is higher than the west.The fouth part puts forward the countermeasures that promote the coordinated developments of the populaiton and the enveriment systems in terms of sustainable development including population,economy,society and enveriment policies.
