城市灌木群落小气候效应的时空分布

如何评价城市绿地规划设计的科学性是当前城市生态学、景观生态学和园林生态学的研究热点。现有研究主要着眼于不同类型绿地内部与周围空间小气候的静态分析,而对于绿地对周边环境的生态过程则报道甚少。笔者报道的试验主要以灌木为研究对象,选取太原市几处有代表性的灌木林,利用仪器对植物群落斑块周边温度和湿度在空间和时间的梯度变化进行了测试,以探索城市绿地对其周边环境温湿度的影响的时空分布特征。实验结果表明:植物的叶面蒸腾是绿地产生降温增湿等生态效应的主要原因。绿地对周边空气温湿度的影响随着与绿地距离的增加而递减。其影响力的大小与温度的变化成正相关。该研究揭示了绿地能够有效缓解城市高温的机制和影响格局,丰富了城市小气候环流理论,对城市规划和绿地景观设计都具有一定的指导意义。     

A MODEL SYSTEM OF A LONG-TERM PROGRAM OF EDUSATION DEVELOPMENT AND ITS APPLICATION

This paper studies a long-term program of education development in the light of the theory and method of system engineering.A complete mathematical-Simulant model system is used to describe the internal regularity of an edu-cation system inside a social-economic tystem,and to put forward a set of efficient method for education development programming.The mathematical-simulant model system dis-cussed in the paper is put to practical use in a regional education programming.     

Regional Architecture and Design Practice

Taking a project practice for example,this paper probed into the design methods of regional architecture in such aspects as geographic environment,traditional folk residence style,space environment and construction material etc.In this paper,one of the developing directions of modern architecture,i.e.the regional architecture design is pointed out first,then,the correlation between regional architecture and natural environment as well as historical culture tradition,space environment and material application of regional architecture,etc.were systematically discussed,it also indicated that the regional architecture should be an organic renewal of traditional folk residence style.It is concluded that the regional architecture should be in accordance with the nature.     

The Design Strategies of Modern Industrial Architecture in China

According to the development trends of modem industrial architecture and combining with the situation of China, the essay first proposes the design strategies of modern industrial architecture in China, and then strongly verifies these strategies with deep analysis of advanced design precedents, in the end points out these strategies are very necessary and appropriate in China.     

Memory,Site,City. Rethinking about the City and Architecture in the Perspective of Psychology and Sociology

Each city includes memory elements. As a precious resource, the city memory exists, changes and continues in reality through visual material objects and cultural sub-consciousness. It is the basic context clue for urban people to apperceive, to experience themselves and their existent environment with the lapse and change of time. Beginning with the concept of memory, this article analyzed the relationship of time, space, human being and environment. It tried to use interdisciplinary research methods and rethink about the essence of city and architecture in the perspective of psychology and sociology, so as to explore the dee Pissues of ideology and value conception in urban design and urban conservation of history and culture.     

Parallel Architectures of the ASIC for Walsh-Hadamard Transform

The design of ASIC (Application-specified Integrated Circuit) has been recently paid a lot of attention to by scholars. In this paper,investigation was made in some respects related with the design of the ASIC for Walsh-Hadamard transform (WHT). These respects include the desing of the dedicated algorithma and their SFGs(Signal Flow Graphs),the design of the VLSI array, bit-string computation, and variable-size function. At the end, resonable VLSI array architecture was presented for the WHT ASIC.     

Determination of Liquid Superheat Limit and Vapor Subcooling Limit in Homogeneons Nucleation Using Density Fluctuation Theory

Based on the development of design of skyscrapers by foreign architects in Shanghai, this essay is offered as a brief introduction and an analysis of these designs and helps to study and absorb the advanced conception of foreign architecture design.
