In order to study the morphological variations among wild Anthocidaris crassispina groups in the southeast coast of China, six groups collected from Daya Bay, Egong Bay, Hailing Island, and Nan'ao Island in Guangzhou Province, Weizhou Island in Guangxi Province and Ningde City in Fujian Province were analyzed in this paper. Six morphometric traits were measured and the degrees of morphological variations among wild Anthocidaris crassispina groups were compared using four multivariate analyses, one-way ANOVA analysis, variation coefficient method, cluster analysis and discriminant analysis. The results of one-way ANOVA analysis showed that there were significant differences in the six morphometric traits between Weizhou Island's population and the other five groups. The variation coefficient analysis showed that the difference between the Weizhou Island's population and Hailing Is- land's population reached the interspecific level. The results of cluster analysis showed that the morphometric characters of Daly Bay's population, Egong Bay's population and Nan'ao's population were more similar, but the groups from Weizhou Island and Ningde City were the most divergent. The discriminant analysis showed that the identification accuracy of A. crassispina was 47.8%-86%, and the total dis- criminant accuracy was 65.3%. All the analysis results above suggest that certain morphological variation has been generated among A. crassispina groups from differ- ent origins due to geographical isolation and different environmental factors. 展开更多

The present study was conducted to determine the green value chain implementations of large and medium size businesses and to investigate the relationships among antecedents, initiatives and results of green value chain implementations. The antecedents of green value chain implementations were considered from four dimensions namely regulations, public concerns, expected competitive advantage and top management commitment; green value chain initiatives were considered from three dimensions namely green primary activities, green internal support activities and green external support activities; the results of green value chain implementations were considered from two dimensions namely economic performance and socio-ecologic performance. A model was created according to the objectives of the study and hypotheses were formed. Multiple regression analyses were performed to investigate the relationships between the antecedents and initiatives of green value chain implementations. A relationship was not observed between green primary activities and economic and socio-ecologic performance. While a positive relationship was observed between green external support activities and economic performance, a positive relationship was observed between green internal support activities and both economic and socio-ecologic performance. 展开更多

In developing countries, the emigration from rural territories to urban areas has brought about some negative impacts strictly associated to a lack of services a drop of ecological sustainability and environment protection with the consequence to worsen the marginalization of these territories. In the world, more than 50% of poverty is located in rural areas and the most incidence of it is in Sub-Saharan African countries; in Latin American nations, instead, the most percentage of poverty is located in urban areas. The aim of this research was to estimate, by a multiple regression model, in 46 countries of Africa and in 23 nations of Souther-Central America, which socio-economic variables were able to play a fundamental role on the rural population and on the development of rural areas in 2000 and 2010 using some statistical data published in the FAO Statistic book. In analysed African countries there has been an increase of people living in the rural space and a growth by 21% of agricultural Gross Domestic Product (GDP). In Southern and Central American nations, there has been a meaningful emigration from rural territories due to an expansion of commercial flows and per capita income in rich areas, thus people have decided to move from the rural territories to the urban territories, worsening the poverty and living conditions in the countryside. 展开更多

Payments for Ecosystem Services: Market Mechanism or Diversified Modes?

Payment for ecosystem services is a concept of environmental protection and method of environmental management that has "purchasing conservation" as a major feature and has grown around the world since the 1990 s. It is stressed by the school of environmental economics that as a voluntary mechanism of exchange between ecological service providers and demanders, payments for ecosystem services can help to increase inputs and improve efficiency. Ecological economics holds that the ecological system and the complexity of the policy environment restrict the functional space of market mechanisms. The negative influence of the objective of giving priority to efficiency on environmental protection and social fairness cannot be neglected; therefore, the exchange mechanism is just one type of eco-compensation models. Here, we posit that payments for ecosystem services is a good tool for environmental protection and increases inputs and efficiency. Although payment for ecosystem services is confronted with challenges in application, it is playing an increasingly important role in the field of ecological services with a relatively high degree of commodification. Payments for ecosystem services can also increase the cost effectiveness of publicly managed environmental projects with the cooperation of other policy tools. 展开更多

From the point of growth units, the growth mechanism of hydrotalcite (HT) crystal is investigated in this paper. Results show that the growth morphology of HT is consistent with the model of anion coordination polyhedron growth units. The Raman shift of growth solutions of HT, Cu-HTlc, and Cu-Zn-HTlc are monitored using Raman spectroscopy. In the experiment, the growth units of Mg-Al-hydrotalcite are [Mg-(OH)6]4- and [Al-(OH)6]3-, and the growth units of Cu-Htlc and Cu-Zn-HTlc are [Mg-(OH)6]4- and [Al-(OH)6]3-, respectively. The growth process of hydrotalcite is as follows: growth units first incorpo- rate into metal layers, then metal layers adsorb An- and H2O, and the growth units incorporate into layer compounds according to this rule. Growth units will have different incorporations and growth morphologies caused by different growth surroundings. Furthermore, the reason why Cu-HTlc is difficult to synthesize is also interpreted in this paper. 展开更多
