A Study Of Yellow River Delta Area Sustainability Evaluation And Spatial Types

Since entering the middle of the 20 th century,the advancement of industrialization and urbanization,made continued increase of the intensity of regional development,ecological environment problem is increasingly outstanding,global population,resources,environment and energy crisis began to exposure,the urgency and the necessity of safety research on ecological environment is more and more obvious.Evolution of regional land relationship and state sustainability assessment is helpful to realize the development present situation and development trend,providing theoretical basis for implementing sustainable development strategy.Based on resources and environment and all the elements of the interaction between the elements of human production and living activities and to study the effect of integrated,parsing different stages "person" and "to" interaction strength and their contradiction of the imbalance,discusses the sustainable development of the typical person system evolution process and the space types of general rules,seek the path of regulating the regional sustainable development,finally through geographical discipline construction actively into the transformation of development of earth system science.This article selects the Yellow River delta Area as the study area the anatomy of the typical system type of person,around each stage of development,sustainability evaluation as the main line,based on the analysis of characteristics and spatial difference of each stage,find out the principal contradiction and the unsustainable effects of the synthetic analysis of the characteristics of people to the region system and space differences,regional sustainability in an integrated perspective.This paper will be divided into six parts:The first chapter is the introduction part mainly introduces the research background and meaning,the related research progress,research contents,methods and technical route and the paper innovation points;Theoretical basis and the related conception of chapter 2 introduces the theoretical basis as required by the thesis writing and defines the concept of the key concepts involved.Chapter 3 sustainability integral analysis part,first of all,analysis the regional sustainable development of the overall characteristics,find out the problems and the unsustainable effects of;Chapter4 of the Yellow River delta area sustainability evaluation and space type research partwith sustainability evaluation as the main line,through sustainability assessment method and way to sustainability,quantitative and qualitative assessment,completing the process of the evolution of the Yellow River delta geography research specific studies each phase space difference of Yellow River delta,and then combined with the natural,economic and social aspects in detail analysis of influencing factors;Chapter 5of the Yellow River delta sustainability transformation countermeasure part through the analysis of the system of sustainable development of population and land constraints and judgment and prediction based on the future development goals,put forward to realize the sustainable development of the Yellow River delta people to countermeasures and Suggestions;Chapter 6 part main conclusion and the future prospects are defined from the concept of sustainability and temporal level,regional level analysis paper main conclusions and make outlook for further research in the future.In this paper,chapter 3 and chapter 4 is the main part,on the basis of the above six chapters,the following conclusions:(1)From the current situation of the development of the Yellow River delta area economy continues to grow,increasing economic benefits,the trend of industrial structure is reasonable,the various economic indicators for good,but there are still structure level is low,unbalanced regional economic development and industrial layout problem such as restricting the regional economic integration;Social subsystem with the accelerating urbanization process,people's living standards continue to improve,increasing the coverage of social security,but there is contradiction in population structure,widening gap between urban and rural areas and other issues;Rich in natural resources,ecological environment system protection process is accelerated,but the development and utilization of the resources,ecological environment problems still not been fundamentally solved.(2)The evolution of sustainable development of Yellow River delta can be divided into two stages: slow development stage before in modern society and modern society after the volatility of the stage of development.Modern society after the volatility of the stage of development and can be subdivided into agricultural resource development of agricultural economy stage(1949-1960),industrial resource development of the industrial economy stage(1961-2000),integrated resource development of efficient ecological economy stage(2000-present).(3)Using the triangle model of the sustainability of the Yellow River delta from2001 to 2015 were analyzed,and it can be seen that sustainability present in last decade from the general sustainability to strong sustainability,economic feasibilityindex and social acceptability toward the good direction development,but the resources and environment rationality index fluctuated changes,the risk of ecological environment has deteriorated,the bottleneck of restricting the sustainable development is still not been fundamentally solved,the state still has the potential to improve sustainability.Sustainability from the Yellow River delta area type evolution,19 municipal,district state of sustainability are increased,the space type experienced by the phase difference obvious transition to a relatively balanced,but the space difference is more apparent,sustainability status generally present the spatial pattern of east west high low.(4)If Yellow River delta wants to go the way of sustainable development,should enhance the level of ecological civilization,constructing the system of circular economy;Focus on strengthening scientific and technological innovation and personnel training,strengthening efficient ecological industry development,reduce the pressure of the ecological environment;To form a reasonable space development pattern,coordinate interregional relationship,form the space structure of sustainable development,promote the regional harmonious development.
