A simple new classical growth model is developed to analyze the relationship between economic growth and environmental pollution, which proves the existence of the sustained growth path. This model is then endogenized to study the interaction among environmental pollution, human capital and economic growth in the long run. The similar growth path is shown and potent influences of different variables...
A distributed watershed runoff and sediment production model, reflecting the influences of the spatial inhomogeneity of underlying surfaces and human activities on watershed runoff and sediment production, is constructed. It can simulate the spatial and temporal processes of runoff and sediment production under different kinds of land utilization, and provide technological support and scientific basis...
Environmental management are collection of environmental standards, green technological innovation related to patent protection system, economic instruments, financial instruments, and other measures to limit damage to the environmental quality of human. This issue Analysis environmental management mechanisms from the economics perspective: Additional new targets affect the uncertainty of environment...
This paper applies the analytic approach of the ecological footprint to calculate and compare the ecological footprint and the ecological capacity of Fujian province over the period from 1993 to 2002 and Taiwan province over two periods from 1981 to 1990 and from 1993 to 2002. The results indicate that land demand per capita of both Fujian and Taiwan increased year by year while the ecological capacity...
To manage coalmine maps and handle the safety production information, on the condition that the SCADA system has been completely built, the Coalmine Safety Information System for a southwest county in China is developed using Visual C++ 6.0 and Visual InterDev 6.0 based on MapGIS. To meet different requirement of different level users, the system adopts the mixed architecture with C/S and B/S. This...
This paper analyzed the characteristics and major human driving forces of cultivated land change in Fuzhou, China, using remote sensing (RS) images, geographic information system (GIS) spatial analysis, and socio-economic data. Based on the RS images and GIS spatial analysis, a change matrix was constructed to detect land-use change from 1989 to 2005. The result indicated that paddy fields and dry...
Crop yield estimation models using remote sensing data were developed to forecast crop yield for Hubei province. Firstly, simulated counties were chosen using productivity zoning method, and the fluctuated yield was obtained by analyzing history trend. Secondly, the correlation coefficient between fluctuated yield and remote sensing index was calculated. Then, the index with the highest correlation...
In this study, the gene encoding purine nucleoside phosphorylase (PNPase) from Bacillus subtilis W168 was identified, cloned and expressed in Bacillus subtilis AG208. The gene encodes a polypeptide of 233 amino acids with a calculated molecular weight of 25,018 Da. The enzyme activity of the recombinant protein (AGPNP) was analyzed by temperature and pH perturbation difference spectra. Results showed...
Two treatments (5- and 15-tillage operations) were conducted to assess intensive tillage effects on wheat production in the Sichuan Basin, China. After intensive tillage, wheat grain yields were 55% and 41% in areas of soil loss lower than those in areas of soil accumulation by 5- and 15-tillage operations, respectively. The redistribution pattern in soil depth affected wheat production with a logarithmic...
