Significance of Implementing ISO9001 and ISO14001 Standards in Tourism Service Enterprises——the Practice at xin Long Tropical Plants Garden

As a China national comprehensive tropical plants garden, the Xin LongTropical Plants Garden undertakes multiple tasks of scientific research, species protection, popularscience education and tourism reception. Same as a global tropical plants garden, it also faces thestrategic tasks of reasonable utilization of biological resources and environmental protection,international exchange and international cooperation and upgrading the level of management. How toupgrade the level of services; how to provide the society with high quality tourism services; how toachieve both re-sources exploitation and environmental protection; how to match with theinternational practice; how to eliminate technical barrier of trade and ensure fair competition etc;all these are the problems of common concern of both domestic and foreign enterprises of tourismservice. The Xin Long Tropical Plants Garden has taken a trial implementation of ISO9001:2000 and18014001:1996 dual standard system since 2001 and passed the certification of CQM (ChinaCertification Center for Quality Mark) in 2002 and gained the certificate of IQNet, so set anexample in implementing standardized management for both domestic and foreign enterprises of tourismservice.

Regulations and Practice on Flue Gas Denitrification for Coal-Fired Power Plants in China

In China, according to the relative up-to-date regulations and standards, the maincontrol measure for NOX emission of coal-fired power plants is, in principle, low NOXcombustion. However, in recent years, more and more newlyapproved coal-fired plantswere required to install flue gas denitrification equipment. This article expounds if fluegas denitrification is necessary from several aspects, including constitution of NOX, itsimpact to environment, operation ofdeNOXequipment in USA, as wellas the differencein ambient air quality standard between China and World Health Organization. It setsforth themes in urgent need of study and areas where deNOX equipment is necessaryfor new projects, besides a recommendation that the emission standards for thermalpowerplants should be revised as soon as possible in China.

Medicinal Plant Use in Ghana: Advancement and Challenges

In Ghana, the use of medicinal plants is a known and an acceptable practice common to all the regions and ethnic groups, with about 60% to 70% of Ghanaians depending on traditional medicine for their healthcare needs. Even though medicinal plants are all over the country and are of great benefits to a lot of Ghanaians, there is little or no proper documentation on medicinal plants use in Ghana;how it all started and where it is today, as well as what is being done to promote its use and some challenges being faced with its use as a country. This paper therefore sought to assess and compile generally, Medicinal plants use in Ghana;focusing on the use of some plant medicine, development and advancement in the herbal medicine practice, as well as associated challenges. Available literature and information on medicinal plants use in Ghana were compiled by searching through electronic database such as Google Scholar, PubMed, Science direct, SciFinder and other relevant websites, as well as books and reports. A brief history, measures taken to develop and advance plant medicine use and some specific challenges facing plant medicine practice and use in the county have been discussed in detail in this write-up. This compilation is believed to bring to book the value of some medicinal plants in Ghana and the efforts being made to promote herbal drugs to complement orthodox medication.

The effect of fertilization on early growth of konara oak and Japanese zelkova seedlings planted in a harvested pitch pine plantation

We determined a suitable amount of fertilizer for konara oak（Quercus serrata） and Japanese zelkova（Zelkova serrata） planted in a harvested pitch pine（Pinus rigida） plantation. Two-year-old bare-root seedlings of konara oak and one-year-old containerized seedlings of Japanese zelkova were planted in April 2011. Three plots were established for each tree species to evaluate each of three fertilization applications. Solid compound fertilizer（N：P：K = 3：4：1） was applied yearly in three amounts（control： no fertilization, F1： 180 kg ha-1, and F2：360 kg ha-1）, every May from 2011 to 2013. We measured the root collar diameter and height, and analyzed the compartmental N and P concentrations. Compartmental N concentrations of konara oak and Japanese zelkova were not consistent based on amount of fertilization. However,the compartmental P concentrations of konara oak and Japanese zelkova were significantly different in the order of F2, F1, and control. Although the differences in growth of konara oak appeared after 3 years of fertilization,Japanese zelkova showed differences after only 2 years of fertilization owing to differences in seedling type. Growth of konara oak was affected by fertilization at F1 and F2 in2013. However, growth of Japanese zelkova was affected only at F2. Nutrient demand of Japanese zelkova appeard to be higher than that of konara oak, at least during the early growing period. Results from this study could be practically used in harvested pitch pine plantations to determine appropriate fertilization regimes.
