Spatio-temporal Difference and Influencing Factors of Environmental Adaptability Measurement of Human-sea Economic System in Liaoning Coastal Area

Adaptability theory is an important tool to analyze the degree, mechanism and process of interaction between human and environment, which provides a new perspective for the research of sustainability assessment. Based on the entropy weight-TOPSIS method and the panel Tobit model from the perspective of adaptability, spatio-temporal difference and influencing factors of environmental adaptability assessment of human-sea economic system in Liaoning coastal area was measured by using the city panel data from 2000 to 2014. The results indicate that: 1) The environmental adaptability of human-sea economic system in Liaoning coastal area rose slowly from 2000 to 2014, the developing trend of each city was linearly related, and Dalian was in a leading position. 2) The different adaptability elements and adaptability subsystem show polarization phenomenon and completely different regional evolution characteristics. The adaptability of human-sea environment system and human-sea economic system rose slowly and had the characteristics of linear relationship, and the adaptability of human-sea environment system is the main reason for the difference of environmental adaptability of human-sea economic system. 3) Science and technology, environmental management, marine economic development level, port construction are the driving factors of the healthy development of environmental adaptability of urban human-sea economic system.

Dynamic Assessment on Regional Eco-environmental Quality Using AHP-Statistics Model—A Case Study of Chaohu Lake Basin

An indicator system closely connected with eco-environment, in which indicator involves in such fields as society, economy, resources, environment and ecology, is first proposed for eco-environmental quality assessment. Then, a hierarchical model with four levels is established by virtue of these indicators and attributes. In the model, weights of indicators and attributes are determined by combining Delphi method with the Analytic Hierarchy Process (AHP) and a statistic method is used to eliminate the influences arising from the differences in dimension and magnitude of indicators. On these grounds, an AHP-statistics model is provided for regional eco-environmental quality assessment. As a case, such AHP-statistics model is utilized in the dynamic analysis of regional eco-environmental assessment in Chaohu Lake basin. Study results show that natural environmental quality in the watershed was in the declining state while social environmental quality was in a markedly improved situation from 1996, and the synthetic eco-environmental quality was gradually and slowly improved under the common influences of both natural and social environmental factors. Example of application testified the capacities of above methodology to evaluate the real and dynamic state of regional eco-environmental quality.

Comprehensive Measurement for Carrying Capacity of Resources and Environment of City Clusters in Central China

Studying the carrying capacity of resources and environment of city clusters in the central China has important practical guidance significance for promoting the healthy, sustainable and stable development of this region. According to their influencing factors and reciprocity mechanism, using system dynamics approaches, this paper built a SD model for measuring the carrying capacity of resources and environment of the city clusters in the central China, and through setting different development models, the comprehensive measurement analysis on the carrying capacity was carried out. The results show that the model of promoting socio-economic development under the protection of resources and environment is the optimal model for promoting the harmony development of resources, environment, society and economy in the city clusters. According to this model, the optimum population scale of the city clusters in 2020 is 42.80×106 persons, and the moderate economic development scale is 22.055×1012 yuan (RMB). In 1996-2020, the carrying capacity of resources and environment in the city clusters took on obvious phase-change characteristics. During the studied period, it is basically at the initial development stage, and will come through the development process from slow development to speedup development.

Measuring coordination of economy-society and resource-environment based on major function oriented zoning: a case study of Pearl River Delta

A reasonable coordination degree assessment of the social-economic development level and the resource-environment quality level are essential to ident the key factory of the development, and vital to determine the appropriate development strategy and achieve sustainable development. The major function oriented zoning plays a role in spatial coordination mainly＇ by spatial guidance and restriction, so. the proposal of major function oriented zoning gives a new train of thought to generate a coordination evaluation of economy-society and the resource-environment system, From the view of major function oriented zoning that considers resource environmental bearing capacity, existing development density and development potential, this paper constructs an index system and model of coordination evahtation with a case study on Pearl River Delta. The results have shown： （I） It can reveal the conflicts of economic-social development and resource-environment quality to ac- curately consider resource environmental bearing capacity, existing development densio~ and development po- tential; （2） The coordination degree between social-economy system and resource-environment system in Pearl River Delta continued to decline in the past 10 years. The spatial extent of coordination evoh,es.from coordina- tion in the whole Pearl River Delta to imbalance in the core areas, and at present, the uncoordinated areas have already diffused from core areas to the outlying regions： （3） Most regions of the Pearl River Delta are in uncoordinated condition When considering the coordination degree of economic-social development and resollrceenvironment quality, not as coordinated as some scholars considered.

Unit Environmental Property Rights: Efficiency, Responsibility and System

The inexplicit efficiency of environmental property rights lies in its fuzziness. Based on the character of environmental property rights discussed, unit environment shows intra relationship between efficiency and duty of environmental property rights, and constructs a symmetrical system arrangement. Through analyzing the possibility and feasibility of unit environmental property rights, the significance of symmetrical system arrangement to avoid the inexplicit efficiency of environmental property rights is discussed in this dissertation from the aspect of the validity of offering and implementing system.

Environmental protection versus economic growth

This paper presents and analyses the differences in the eco-models implemented worldwide （such as whether and how carbon taxes being ＂recycled＂）, or in their efficiency parameters （inconsistent parameter values that account for different results）. This is the assumption that a real tradeoff exists between the production of environmental goods. The present article empirically proves that something must be given up in order to gain something else, and once equations are specified to trace out the path of the economy over time, the natural economic formulation of such equations will embody the notion of economic and bio-tradeoffs.

Basic Structures and Political Implications of a Sustainable Welfare Model

A synopsis of political welfare concepts, which are currently discussed under labels such as ＂green growth＂, ＂zero growth＂ and ＂degrowth＂, has identified fundamental shortcomings concerning the informational bases of the complex links between ecological, social and economic systems, which were taken into account in the creation of the concept. In the development of a concept for political action, a rationally acting environmental policy cannot neglect reflecting on which economic, ecological and social contexts have to be taken into account and on which normative statements its decisions should be grounded. The proposed sustainable welfare model consists of a positive impact and a normative decision model. The positive model provides a description of the ＂world＂ with which the effects of the various options for action on the environmental, social and the economic systems can be assessed. The normative model is a tool for selecting and assessing the options for action in pursuing the desired goal of sustainable welfare development. Principally the key environmental goals are prearranged to socio-economic goals. The model at hand provides the reference points for the development of a sustainable welfare concept, which can be used as a political action plan in the context of environmental policy.

Development of the eco-community planning studies under the concept of low-carbon

Universality of low-carbon eco- city planning measures, Government regulation, as an important planning means to guide urban development urban; it is an allocation mechanism for land and space resource. Low-carbon eco- city planning is especially important for China as it is in a state of rapid economic growth, urbanization acceleration, carbon emissions increase, ecological environment deterioration and intensifying economic transformation. During the process of low-carbon eco-city planning, we must consider the whole range of temporal and spatial distribution of the city and grasp the overall coordination system of time and space. We should regard it as a system of the entire biosphere and regulate urban according to true features of ecosystems, that is in a basically a three-dimensional, integrative compound patterns. We need consider the natural ecological system factors, technological physics factors, economic assets factors, social and cultural factors as well as various humanitarian factors among the urban system structure; consider the impact of the internal and external urban environmental systems; make them interact and influence each other and restrict each other through the planning of the urban system material flow, energy flow, information flow and capital flow; insists the evaluation basic of the healthy development of urbanization and the of exercise macro -control on the dynamic representation＂ of the city development, the ＂qualityrepresentatiou＂ ofthecity＇ s connotation and the air representation＂ of the city state in order to overcome the ＂ urban disease ＂ by development, to reduce the ＂ urban disease ＂ by planning, to treat the ＂ urban disease ＂ by management. Only by bringing the design and control into the scope of long-term planning and governing can we effectively monitor and guide the development and construction of low-carbon eco- towns.
