Review Article of Landscape Metrics Based on Remote Sensing Data

This article describes metrics in order to quantify landscape structure. Landscape metrics are offered and designed to be as versatile as possible using several programs. In this paper it is attempted to （a） collect all the metrics found in the literature, （b） classify them, and （c） evaluate them through their use. An extensive investigation of the literature has been performed. Small discussion of each metric is provided to its concept, definition, use, way of calculation and in some cases contribution to the sustainable development. The frequency of used papers per each index has been taken into account. The most used to the least used six metrics have the following order： Area/Density/Edge; Isolation Proximity; Diversity; Contagion Interspersion; Shape; Connectivity. Moreover, the frequency of used papers is divided into five groups, i.e. group A till group E. Concluding, it has been provided an explanation of the results regarding to the four indices of group A and two indices from the group B.

RELATIVITY AND SUSTAINABLE DEVELOPMENT

From the realism of science, and taking the guide of EINSTEIN’s Relativity as guide, this article called in question the present theory of the sustainable development by the rational thinking of philosophy and a close logic inference. It is found that there are many paradoxes to the theory. Through more deepening and meticulous inference, we arrived at philosophic language of science about the sustainable development. The sustainable development is "non-sustainable development", and the non-sustainable development is "the best sustainable development". While carrying out philosophical principle thinking and repeating science demonstration for the sustainable development, this article got further confirmation that the existence of human being at the minimum environment cost may help them obtain motive power of the sustainable development. In fact, this foundation motive power exists in the flow of development in different organization levels, meanwhile it exists in strategy of intuition living of the ancient people. Only in relative lower environment cost to live can we get the support system of science for the sustainable development, and be able really to achieve the basic goal of the sustainable development.

Circular Economy Development Mode Based on System Theory

The paper tries to explore circular economy from the viewpoint of the system theory. Circular economy is a kind of complicated economic activity, and it is a wholly new ecotype economy proposed by Western countries after they had summed up many experiences and lessons from traditional economy. It is an entirety and has many layers. It keeps an open and dynamic balance. Because the system theory is the theoretical foundation of circular economy, we should systemically analyze and study circular economy from the macroscopic view, correctly grasp its operational laws, improve its service functions, and realize human beings' sustainable development. The paper introduces the content and general characteristics of the system theory and the idea of circular economy. Then it analyzes circular economy based on the system theory. The paper concludes that the integration of circular economy and the system theory can promote the functions of circular economy.

From Compact City to Smart City： A Sustainability Science ＆ Synergy Perspective

This brief conceptual paper contributes a sustainability theoretic perspective of an urbanization paradigm known as Compact City. Compact City is an urban planning and development concept which promotes relatively high population density associated with an integrated and mixed-use land district. It is enabled by transit-oriented development and results in low transport-related energy consumption and reduced the GHG （Greenhouse Gases） pollution. Compact City conserves the natural capital of land mass and subscribes to the strong sustainability ethics. ICT （Information and Communications Technology） could be deployed to optimize the Compact City operations by first tackling some of the development problems associated with Compact City and also unleashing new urban innovations and functionalities to achieve sustainable urbanization. The paper suggests and elucidates several general systemic synergies archetypes such as co-benefits, cascading, ICT infrastructure reuse, etc., which could be leveraged to facilitate the emergence of compact green smart and resilient city. These archetypes are solutions to the Compact City paradigm thus conductive to the development ofa Sustainability Science of Compact City.

A fast method to evaluate water eutrophication

Water eutrophication has become a worldwide environmental problem in recent years.Once a water body is eutrophicated,it will lose its primary functions and subsequently influence sustainable development of society and economy.Therefore,analysis of eutrophication becomes one of the most essential issues at present.With the ability to deal with vague and uncertain information,and express knowledge in a rule form,the rough set theory(RST) has been widely applied in diverse domains.The advantage of RST is that it can compress the rule and remove needless features by reduction inference rule.By this way,the rule gets effectively simplified and inference efficiency gets improved.However,if data amount is relatively big,it could be a process with large calculated amount to search rules by looking up tables.Petri nets(PNs) possesses so powerful parallel reasoning ability that inference result could be obtained rapidly merely by simple matrix manipulation with no need for searching rules by looking up tables.In this work,an integrated RPN model combining RST with PN was used to analyze relations between degrees of water eutrophication level and influence factors in the Pengxi River of Three Gorges Reservoir.It was shown that the RPN model could analyze water eutrophicaion accurately and quickly,and yield decision rules for the decision-makers at water purification plants of the water quality and assist them in making more cost-effective decisions.

Research on the Knowledge System Framework of Eco-industrial Engineering

With intensified contradiction between the rapid devel- opment of modem industry and the carrying capacity of natural environment, coordinating the relationship between economic benefits and ecological benefits is a significant issue to be solved for modem industrial engineering. This paper firstly conducts the comparative analysis between traditional and ecological industry as well as traditional and modem industrial engineering, and in- dicates that eco-industrial engineering is an inevitable choice for sustainable development of modem industrial engineering; Then, based on industrial ecology, environmental economics and sustain- able development theory, the connotation and definition of eco- industrial engineering are proposed, and the theoretical and practi- cal development of the concepts of eco-industrial engineering are further investigated. Furthermore, the research subject, research content, academic system architecture and evaluation methods of eco-industrial engineering are discussed. Finally, combining the current scientific and technological development, we put forward the important scientific value and practical significance of con- structing eco-industrial engineering for the utilization of these concepts.

Sociology and Degrowth： Visions of Social Change, Entropy and Evolution in a Waydown Era

In the last few years, different sources pointed to a same message： industrial civilization had entered into an overshoot mode; the natural limits to growth had been already surpassed. This frontier does not wait for us in the future; it already belongs to our past. If population and the economy are truly beyond the limits, then current visions and theories of social change would be deeply perturbed. If the development era is approaching its end, then many sociological theories on current societies will share the same destiny： sustainable development doctrines between them. It is worth to examine theories that explicitly look at the social world which at least are not incompatible with it. Four different approaches are discussed in this context： governance of complexity, post-development and alternative local development, utopian sceneries of a prosperous waydown, visions of collapse and the die-off. As a conclusion, the paper accepts an evolutionary perspective supports that there are some potentials for conscious social change, but it does not justify the belief in a particular only line of history. This conclusion does not satisfy the desire of knowing the future; nevertheless it may be the only one possible. The future is not written. Neither in history nor in evolution; not even in the mixture of history and evolution that conforms us as inhabitants of the Earth.

Environmental Analysis of Packaging for Soft Drinks Using the Life Cycle Assessment Methodology

The knowledge of a product＇s life cycle is the first step on the search of sustainable development. The life cycle assessment （LCA） is an important method because it allows an environment accounting, where the extraction of natural resources and energy of the nature are considered and the ＂returns＂ to the same one and allows in evaluating relative potential the environment impacts generated. The present work had as objective to make an analysis of material and energy flows of the life cycle of three types of packaging for soft drinks： glass bottles of 390 mL, aluminum cans of 350 mL, and bottles of PET of 2,000 mL. The study considered processes since the extraction of raw materials for production of the packaging until the stages of recycling, after the consumption of the soft drink. For the research, an inventory analysis followed the LCA methodology. The main critical points of generation of negative environmental impact during the life cycle of each packaging had been the identified and quantified data in this study. The consumption of natural resources like water and other raw materials and energy, the generation of atmospheric emissions, solid wastes and wastewaters had been the analyzed categories. The results showed that, in accordance with the scenes and defined variables, the most important conclusion was that the bottle of glass presented a less favorable scene to the environment in comparison with other packaging.

Sustainable livelihoods in a Coptis-planting based rural community:a case study in Shizhu County,China

Coptis chinensis is a medicinal herb used in traditional Chinese medicine.This research features a case study in Shizhu County,China.Participatory Rural Appraisal(PRA) is used as the main tool for data collection.The study demonstrates that the current method of Coptis planting leads to forest destruction.Even with reforestation measures,it leads to the loss of biodiversity in the forest.It also shows that farmers cannot get satisfactory economic returns from Coptis planting,as the return is unstable and unpredictable.One alternative to the current Coptis planting mode is to incorporate it into the agroforestry system.Water shield planting also serves as a good alternative to Coptis planting itself.Improved methods of management,post-harvest processing,and marketing of Coptis are also proposed and analyzed.The intended contribution of this paper to the theoretical debate of sustainability shall be the provision of an example showing how agricultural production affects forest conservation.It also presents redressable measures to the negative consequences.Besides,one alternative livelihood pathway for the rural community in this case study is suggested.
