On Green Lighting Planning and Design of the City

The energy-conserving environmental protection and the culture characteristic protection are two themes to the sustainable development of modern city,and the green lighting project is an important condition to ensure sustainable development of the city.But now,in some lighting projects the energy consumption and economy power capability were ignored;some design tactics are identical and in the green lighting projects the whole lighting of the city was not considered,which cause the crisis of losing the city characteristic.This paper proposes the green view of city lighting planning,and points out that the energy conservation,environmental protection,economic feasibility and culture characteristic must be considered synthetically in the city green lighting planning and design to guarantee sustainable development of the city.

Exploring Harmonious Protection of Land Resources in City Construction

Urbanization in China is at an essential point in its transformation from the initial stage to accelerating stage. With quick expansion of city scale and large occupation of land for urban construction, the contradiction between land resource shortage and people's living needs becomes more and more prominent. It has great affection on the grand plan of China's sustainable development of economy and society. How to adjust the relations between the development of urban construction and protect the land resource, promote the rational use of urban land, perfect and complete the protection system of land resource for improving the efficiency of urban land use. In order to conserve land resource and find a sustainable way for development of people's living and environment construction, the above mentioned problems are the most important issue for urban construction and important subject of this paper.     

基于能值理论的福州市生态足迹分析

生态足迹是衡量一个国家或地区可持续发展程度的一种方法,定量反映人类活动对生态环境的影响和破坏程度。在对传统生态足迹模型进行简要分析的基础上,提出了基于能值分析理论的生态足迹计算的改进模型,对福州市的生态足迹进行计算及分析。结果表明,2006年福州市人均生态足迹为1.29 hm2,人均生态承载力为0.17 hm2,生态赤字为1.12 hm2,福州市的生态系统处于不可持续状态。与传统生态足迹模型计算结果进行比较研究,结果一致。但改进后的生态足迹模型更具合理性,更真实的反映了区域的生态资源利用状况和可持续发展能力。     

The peri‐urbanisation of Shanghai: Planning,growth pattern and sustainable development

Abstract: With the increase of global integration, the peri‐urban area (PUA) of megacities in Asia has become a favourite destination for foreign direct investment (FDI). This paper uses the PUA of Shanghai as a case study to investigate the impact of global forces on the urban expansion of the city, and the link between urban growth and sustainable development in this mega‐urban context. Shanghai has grown impressively during the past two decades in terms of economic and physical transformation. Much of this transformation has rested on the unbridled exploitation of land and other environmental resources in its peri‐urban area. This is characterised by the designation of development zones and the concentration of manufacturing FDI, resulting in dispersed growth and environmental degradation. The disruption of the physical environment, combined with the concentration of the urban poor in these areas (in particular ‘temporary migrants’), has turned the PUA into a potential crisis point threatening the social and economic development of the city.     

A Study of the Index System for Sustainable Development of a Town

The sustainable development of a town is a comprehensive concept often considered in terms of several aspects such as economical, environmental, ecological, social and cultural.

Empirical Study on the Sustainable Growth of the Public Companies in China

The sustainable growth is the corporation's final object to the maximum of the stock-holder's wealth. To validate the development of the Chinese public companies after Dengxiaoping's Nanxun speech ,this paper tests the sustainable growth status of the Chinese public companies during the period from 1993 to 2000 by using mathematical statistics method and sustainable growth model brought forward by Robert Higgins and James Van Herne. These companies are classified by trade. The test results show that no trade realized sustainable growth except electronic and electric trade. Results also indicate that public companies in light industry and agricultural sectors have a trend of under-investment while those in other sectors have a trend of over investment.     

Main Factor Analysis on the Sustainable Growth of the Public Companies in China

With the sample of Chinese A-stock public companies which appear on Stock Exchange of Shanghai and Shenzhen before 1994,and by using the factor method and regression,this paper finds out and explains the equilibrium relation among sustainable growth of Chinese public companies,profitability and capability of debt-repayment and capability of operation. This paper discover: (1)The sustainable growth rate of a public company is in inverse proportion to asset-debt ratio, but in direct proportion to current debt ratio as well as acid test ration. (2)There is a positive correlation between the sustainable growth rate of a public company and its profitability. That's to say, the higher earning rate, the higher sustainable growth rate.(3)The sustainable growth rate of all public firms other than those of the commerce industry is positively correlated to the growth capacity.(4)Apart from the commerce industry, there is a positive correlation between the sustainable growth and the operation capability of the public companies, regardless of their integral sample, industries sample and scale sample.
