Landscape Design Method of Sustainable Development Based on the Modest Principle

＂Over＂ phenomenon exists in all fields of society, and over thoughts and behaviors not only waste resources, but also destroy the ecological environment.Landscape design is also facing the dilemma of over planning, over design and over construction. Based on the paraphrase and explanation of ＂degree＂, the principle for modest landscape design with the concept of sustainable development was explored through the analysis on the concept of sustainable development, which emphasized the ＂degree＂ standard in landscape design, and the combination of regional features with native features to carry out ecological design, with the aim to facilitate the landscape designers to design the ＂modest＂ landscape with sustainable development.

Behavioral fragmentation of waterfowl habitat and its landscape ecological design in Shuangtai-hekou Reserve,Liaoning,China

Behavioral fragmentation of wildlife habitat is discussed. Using “buffer” module in ARC/INFO, behavioral fragmentation habitat of Red crowned crane, Saunders gull, Oriental white stork and Siberian white crane was calculated in the Shuangtai hekou National Reserve, Liaoning Province, China. The result showed that breeding Red crowned crane, Siberian white crane and breeding Saunders gull are very sensitive to fragmentation factors. Suitable habitat is so little for more than 2000 Saunders gull to breed. The reserve only has a capacity of 38 pairs for breeding Red crowed crane. Two key measures were made. First, dismantles all the abandoned oil wells and recovers the original ecosystem to decrease the fragmentation effect, directly benefit to breeding or migration of Red crowned crane and Oriental white stork. Second, recovers the Suaeda tidal mud flat from artificial shrimp and crab pond in the kernel zone of the reserve to enlarge the habitat area of Saunders gull and Siberian white crane.

Ecological Planning and Design of Urban Green Space System of Sanya City

The construction of International Tourism Island has accelerated the development of Sanya City. The population aggregation and the external extension of urban area have brought a lot of negative effects, such as discontinuities of green space matrix, dysfunction of green wedge permeation, deficiency of eco-corridor, structural imbalance of green space system and so on. The overall layout of Green space system known as "One Belt & Three Bays, One Core & Six Towns, Two Axes & Three Wedges, Two Net Synchronous-construction" strengthens the eco-connection among different groups and green space in central area of the city, and realizes the collaborative construction of both resource corridor and landscape corridor. The eco-layout of green core, green corridor and green patch helps keep the integrity of large vegetation patches, enhances the eco-connection of different types of green space and improves finger-shaped network of urban green space. The most efficient way to promote the circulation of urban ecosystem and the positive development of Sanya City is to plan multilevel and three-dimensional eco-space structure and maximize ecological benefits of green space system.

TOWARDS A FOURTH ECOLOGY: Social and Environmental Sustainability with Architecture and Urban Design

The architect has always been interested in the social and cultural dimensions while creating architecture for people to last,with the help of building science and technology.Science could solve some problems,but is yet to solve many of the problems of urbanization in human history.Perhaps many of the problems can only be solved with careful under­standing of human behavior,social intercourse,and economics in relation to the urban environments and organiza­tions,and the natural environment simultaneously.There seemed to be a divide between the way an engineer and an architect think and practice in making a build­ing and a piece of architecture,where the former is highly mathematical,and the latter deals with cultural poetics and a whole range of social and technical issues of which the physics of the environment is but one dimension(Bay and Ong 2006).It may appear natural in this age of environmental crisis and rapid urban development in many cities that the current Ecologically Sustainable Design(ESD)system,which is mainly based on science of the physical world,would be readily accepted by the architect in practice and education.Many of the current ESD guidelines can contribute to the avoidance of a further decay of the earth,thus pre­venting droughts and floods,etc.,and hope to maintain the status quo of the environment for all the“business as usual”social-economic activities.With more world leaders of the developed world agreeing in principle on the need to address climate change,perhaps a lot more will be done based on the engineering models for ecologi­cally friendly planning,commerce,industry,and design.There could be a cognitive bias3 of overconfidence and systemic error that the predominantly engineering focus to keep climate change at bay will solve the problem of sustainability in various parts of the world.The current limited concept of“ecological”or the“green”design does contribute to sustainability,but is quite limited and not the whole picture of sustainability.The concept of sustainability involves the dynamic and complex balance of environmental(man-made and natural),economic and social dimensions,from many earlier sources including the theory of the Third Ecology(Chermayeff and Tzonis 1971)about social ecology directly related to the man-made urban fabric,and recently,the much accepted pervasive framework of the Brundtland Commission Report 1987:Our Common Future,which included more discussions about the interrelatedness with economic equity and the natural environment.Foremost and ultimately it is about promoting and ensuring social quality of living now and sustaining that into the future,for all nations,the rich and the poor,through solving the matrix of social,economic,and environ­mental problems.From the perspective of the theory and practice of architecture,this paper discusses the following issues:1.Belief in science,disenchantment,symbol of failure of modern architecture-Pruitt Igoe;2.An anti-thesis to Pruitt Igoe-Bedok Court;3.The cultural concerns and preparametric design thinking process of the architect;4.Architecture,social science,cultural value,social capital,behavior,and ESD;5.A Fourth Ecology,multi-disciplinary research by architects,social scientists,and engineers.

ECOLOGICAL DESIGN PRINCIPLES AND THEIR IMPLICATIONS ON WATER INFRASTRUCTURE ENGINEERING

Today’s water infrastructures are the outcome of an industrial revolution-based design that are now at odds with the current sustainability paradigm.The goal of this study was to develop a vision for engineering sustainable water infrastructures.A list of 99 ecological design principles was compiled from eleven authors and grouped into three themes:(1)human dimension,(2)learning from nature(biomimicry),and(3)integrating nature.The biomimicry concept was further divided into six sub-themes;(1)complex system properties,(2)energy source,(3)scale,(4)mass and energy flows,(5)structure,and function,and(6)diversity and cooperation.The implications of these concepts on water infrastructure design suggested that water infrastructure should be conceptualized in a more holistic way by not only considering water supply,treatment,and storm water management services,but also integrating into the design problem other provisioning,regulating,cultural,and supporting ecosystem services.A decentralized approach for this integration and innovation in adaptive design are necessary to develop resilient and energy efficient water infrastructures.

The optimization meas- ures had a significant effect for prevention and control of the non-point source pollution in the water source protection area. [ Conclusion] The re- search provided scientific basis for promoting ecological construction of the small green basin in Dahe Reservoir water source protection area of Di- anchi Lake basin.

Using Geospatial Information Systems in Analyzing Urbanization Impacts on Stream Habitats in Southern Mississippi Coastal Ecosystem

The proliferation of urban development with concentration in population and human-environment interaction has intensified around urban environments. This has resulted in the degradation of urban environments, overuse of natural resources and widespread pollution of ecosystems, The patterns of design initiatives continue to follow unsustainable path with impacts on stream ecosystems. Accordingly, the paper adopts geospatial information systems and sustainability principles for the identification and sequential mapping of stressors impeding natural systems in Southern Mississippi. The results not only reveal that the study area experienced some significant changes in its watershed environments, but the stream habitat ecosystem remains under stress. The recommendations for mitigating the problems range from policy considerations to the adoption of ecosystem approach.

Prioritizing Alarms in Real-Time： Intelligent Alarms Advanced System

During the operation of complex process, such as oil production or refming, abnormal situations may occur, leading to an alarm flooding. Alarm flooding is the signalling of a large number of alarms in a few minutes, in such a way that it is impossible for the operator to attend to all alarms. On these occasions, it is usual that the operator leaves the alarm summary list and gets an analysis of the plant through the screens of the DCS （digital control system）, seeking to understand the situation. The alarm summary list ceases to be a useful tool. In such cases, the operator might have the aid of a filter that would present the highest priority alarms and other information associated with them, enabling him to gain a better knowledge of the situation. This paper describes the interface of a system aimed to help the operator to have a more comprehensive knowledge of the process （a better situational awareness） during process upsets that cause alarm flooding, recovering the utility of the alarm layer to the safety of industrial processes.

Ecological Ways to Design the Tropical Coastal Cities

Design with ecology has been a newtrend of design in the world due to the globalenvironmental issues.Tropical coastal cities need to bedesigned according to ecological principles thanks totheir high visual and ecological sensitivity.Ecological de-sign requires designers to respect environmental limita-tion and advantages and to create a diversity of habitat,and hence of opportunities for the coexistence of di-verse organisms (including man himself).This paper ex-pounds the characteristics of the approach,shows sometechniques and suggests the difficulties and some possi-ble ways for designing with ecology in China.
