Based on some theoretical and empirical research on environmental Kuznets curve (EKC), this paper introduces the environmental technical innovation and environmental investment into Salow growth model to discuss the relationship between GDP per capital and the emission of pollutant By the dynamic simulation and parameters analysis, the results of the model indicate: (1) when "green" technical progress and environmental investment are fixed, the relationship between GDP per capital and the emission shows the linear relationship; (2) "green" technical progress can lead to the positive growth rates with a decreasing level of emission, which is compatible with an EKC; (3) the proportion of the environmental investment can lead the different growth rates and level of emission. These results can explain that developing countries are "too poor to be green".展开更多

The implementation of the Virtual Reality VR used 3D-Games Studio with Lite-C software. The authors also experiment with the use of a VR device, i.e. 3D E-Dimensional wireless goggle to improve the feel of presence for the user of our application. The authors created the original elements of UI campus environment, such as, buildings, trees, campus buses, cars, and bike tracks, as well as obstacle in the pathways into 3D virtual shape that resembles the real UI campus environment. The bicycle movement, camera perceptions, and object collision handling have also been implemented. Our application is subsequently tested by the users in terms of the general object condition, user's respond to the virtual reality environment and the future development. Some result of implementing the same environment using Alice has also been shown.展开更多

At the same time, with the improving quality of people's lives, we must pay attention to production of pollution-free green fruits. This paper, from the point of ecological economics, takes the example of date trees for example, presenting the connotation of ecological economic forest and main construction technologies, in order to provide basis for the industrial development after returning cultivated land into forests.展开更多
