Abstract: This paper selected Yicheng City in Huibei Province as research areas to analyze space distribution characteristics of rural settlements. The results show that the scale of rural settlements in Yicheng City is rather small, and the differences between the settlements patches are very large. With the increase of buffer radius of roads and rivers, the settlements decrease gradually. On this basis, this paper provides suggestions for optimization of rural settlements in Yicheng City. Keywords: Rural Settlement, Space Distribution Pattern, Optimization

Abstract: Benefit evaluation plays a very important role in the guiding of feasibility analysis and decision-making of rainwater utilization projects. This paper evaluated the benefits of roofwater reuse project in Jinan city; it is shown that the project has a national economy benefit obviously with a deficit in financial appraisal. The treated roofwater was used directly or injected into karst groundwater with deep well, which has a great ecological and social benefit, especially for the protection of springs in Jinan city.

Abstract: The historical areas are frequently early-developed districts in the city. Due to the urban modernization, the cultural heritages composed the historical area are demolished and then replaced by communal facilities to upgrade the urban faculties. However, the urban context is the outcome of the social transition of the city; therefore, the spatial characteristic of historical area responds to the process of the development of the city. The value of the cultural heritages is not only the its own historical significance but the contemporary living culture of the city. Because of the large spatial scale, the conservation and regeneration of historical area needs a long-term process with interdisciplinary professional issues. As a result, the current problems are that the policy is dominated by government and scholars while local people are difficult to participate, and is more emphasis on the outsiders and tourists than inhabitants. By several years participant observation, this research found out that the participant process of the activities can bring local groups and residents to identify themselves with the historical area; and the participant model with multiple and integrated local organization brings themselves up on professional knowledge and ability in the aspect of the cultural heritages. To present and to interpret autonomously the cultural connotation of the activity by the local people is helpful to continue the development of the dynamic culture. On the other hand, the transformed and multi-used places for the activity can respond to the dilemma of the modernization and the conservation. The cultural heritages related to activities may become supportive environment during the development process of the historical area in the city.

Abstract: San ye House Village are located in Farming-pastoral zone of eastern Inner Mongolia after a hundred years of development history, from mainly nomadic settlements into agricultural and pastoral settlements. The evolution of the settlements' pattern experienced a total of three stages. With the combination of different periods of settlement pattern analysis, the characteristics of San ye House village settlement pattern development is studied and the reasons for its formation and evolution process are presented.

Abstract: The soil water content in a region is closely related to plant growth. The coal Mining has a strong influence on the soil in Mao Wusu sand land. This study investigated the relationship between the soil water content and the collapse Degree Land of Coal Mining. Samples of the collapse land were analyzed for the soil water content in different slope locations in summer. The soil moisture changes are basically same in different slope location regardless whether it is in subsidence area or not when no rain occurs within two weeks in summer, and soil water content is relatively low in slope button, and a relative high in the other slope location, the water content in the control area and subsidence area follows from high to low by: 0a> 3a> 2a> 1a. The soil water content of the control region each layer is significantly higher than that of the subsidence region.The soil volumetric water content of the sample land on both sides of the subsidence cracks is less than that in the control land in the experimental period. The water content of relative subsidence side is higher than in the exposed side, and the water content is shown the law of the control area>light >light-exposed>medium>medium-exposed>heavy>heavy-exposed.

Abstract: In 1987, the Brundtland report defined sustainable development as development that meets the needs of the present without compromising the ability of future generations to meet their own needs. The 30 percentage of the whole world greenhouse gas per year come from buildings. In many situation when architects design tall buildings, they often take into more consideration operational efficiency instead of some influence of environment. The consumption of energy ascend dramatically in developing counties, which leads to air pollutions and increase of greenhouse gas in these countries. In China, the number of tall buildings are increasing and these tall buildings take large proportion of energy consumption. The number of tall buildings was 400 until 2000 and the energy consumption of huge tall buildings is 6 to 8 times more than common buildings. Therefore, how to reduce energy consumption in tall buildings plays a vital role in sustainable development. The holistic sustainability includes three aspects which are economy, society and ecology. The purpose of this essay is critically assessing sustainable tall buildings in China and UK. Then limitation of holistic sustainability of building scale in China would be analyzed and how to enhance it.

Abstract: Green building is being paid more attention at present with the development of resource economizing social, and there are wider development space for water conservation technology. Water conservation evaluation is accordingly becoming an important part in green building study. A green residential area, which including a series of water conservation project is selected as a study case. With evaluating its water conservation of incremental cost, rainwater utilization and comprehensive benefit, the paper aims at consulting on the investment decision in green building’s water conservation technology to reduce the environmental impact on the earth due to water consumption and wastewater discharge.

Abstract: This paper analyzed the three large-scale residential districts by comparing their natural environments, residential types, supporting facilities and economic developments. It concluded that the city residential areas in modern time should follow the requirement of sustainable development of environment, economy as well as society so as to minimize the drawbacks of suburbanization.

Abstract: Urban sustainable development is a compound system (consisted of urban economy, social background, natural environment and urban civilization) whose core lays on the minimalization of environment pollution and the cost of natural resources without impairing urban economy and life quality. It aims to achieve a harmonious development between society, economy, environment and resource, and to keep a virtuous ecological cycle as well. Based on this theory, this paper divided the urban sustainable development system into four sub-systems, namely, economy, society, nature and civilization, with a corresponding evaluation index system set. Further, by applying entropy evaluation method, the actual level of Tianjin sustainable development was evaluated. According to research result, though fast sustainable development has been achieved, Tianjin still has the tendency to slow down, so positive measures should be taken to incent a harmonious and swift development of each sub-systems and to maintain a stable and consistent development of Tianjin.

Abstract: Abstract. On the background of related statistical data of Liaoning Province from 2004 to 2011,this dissertation offered a comprehensive analysis relating construction industry development to resource-environment through a coordination model,which supplied empirical studies for construction industry and resource-environment of Liaoning province.The research result shows that the coordination degree and coordination development degree between construction industry and resource-environment in Liaoning province increased gradually from 2004 to2010,but began to decline after 2010,the coordinated development situation is not optimistic.In the end,it mentioned several solutions and suggestions which can promote to this coordinated development in the field of construction industry.
