Abstract: As one of the four landscape elements, the plants were very important to the landscape quality. According to the needs for construction of conservation-oriented landscape, this paper indicated some problems and faults existed in the uses of landscape plants currently, such as the open lawn with less comprehensive effects, pursuing to transplant big trees and exotic plants for feature, etc., based on the introduction to its status and importance. Then, three-point strategy was put forward for proper uses of landscape plants and improvement of the whole landscape construction.

Abstract: In the present trend of pursuing green life and promoting natural purpose that ,as the closet garden landscape to peoples’ living, the house garden has understandably become the most important media for the residents to enjoy the baptism and close to the nature. The thesis discussed about the design theory and method of different kind of house garden, and elaborated the basic concepts of house garden, analyzed the features of the house garden landscape system, and finally pointed out the content and development trend of the house garden design, so as to discuss the future direction of the house garden.

Abstract: Haikou is located in tropic climates in China. The outdoor environment in summer is too harsh to stay here. However, the traditional architecture, namely arcade, still survives in the severe climate. Its indoor and outdoor parameters of arcade are tested in field to research its thermal environments. The heat stress index is used to study the adaptability mechanism of arcade and local human to hot and humid environment. It proves that the metabolic rate and wind velocity are main and adjustable factors to reduce heat stress in such wretched weather. On the condition of metabolic rate below 60met and wind speed above 0.7m/s, the healthy adult can work normally in the arcade or on the corridor. So the human in tropic area should keep their metabolic rate and period staying out in the summer daytime as less as possible, and the architects should make full use of the local wind speed to organize natural ventilation.

Abstract: In the established model of economic evaluation, it considers the impact of construction conserves energy elements of existing buildings and adopts payback period of dynamic energy as the evaluation criteria. It proves that the model has practical value by using DeST-h software to simulate building energy consumption of existing buildings and retrofitting buildings.

Abstract: The soil-cement is applied in hydraulic engineering, construction engineering and highway engineering. It needs take much time and energy to do the experiment of soil-cement design, because the influence factors of soil-cement unconfined compressive strength are many. The study is based on the former experimentations, and quantitative analyzed relationships among soil-cement unconfined compressive strength, earthiness, cement mixing amount and curing time by nonlinear curve fitting. Then, rational experience formula is given in this paper. It is tested in Nantong Building foundation excavation project, and the result proves that formula is practical.

Abstract: The ecological environment of ethnic architecture is a major task facing architecture scholars. By spot investigating of Hani nationality residence in Yuanyang County, Yunnan Province, the article aims to explore and research the residential culture pattern of unique harmony between man and nature which is presented by Hani nationality based on man and nature in harmonious coexistence. It also discusses the significant ecological adaptability of settlement from overall layout and planning of settlements, landscape of settlements, and application of building materials.

Abstract: FA-FGD mortar and concrete were manufactured and tested the main performances. With WFA-FGD taking 80~85% of the total composite binder by mass, mortar used in buildings was provided with good workability, enough mechanical properties specified for masonry in China, low drying shrinkage and strong sulfate corrosion, which was suitable for plastering or coating inside and outside walls. With LFA-FGD more than 30% in proportion, middle-strength concrete showed satisfactory workability with no segregation, no bleeding and low slump loss, stable strength development and low brittleness, about 60% of the domestic standard limit of wear mass loss in the specified test, good impermeability as well as excellent cracking resistance.

Abstract: It introduces small high-rise building concepts, discusses the calculation of solar hot water system, which includes the collection of raw data, the determination of solar collector area, the size of heat storage water tank and hot water system type as well as summarizes it as a reference for engineering design.

Abstract: Based on the view of construction market in towns and villages energy-saving housing in China, combining the theory of information asymmetry, this paper will analyze the reasons of information asymmetry existing in construction market of towns and villages energy-saving housing and investigate the problems of information asymmetry and adverse selection between the real estate developers and residents. Referring to the advanced experience from abroad, it can be argued that establishing an appropriate building energy-saving technology evaluation index system is an effective way to solve market failure in towns and villages housing market.

Abstract: Protection of historical and cultural sites and exploitation of underground space became the two important weights on both ends of the modern Luoyang urban development scales. This essay is about the mode by combining into development of underground space and protection of cultural relics. Three aspects have been analysis by citing examples.
