Striving for efficiency,harmony and vitality─A human ecological approach to urban sustainable development

Sustainability can only be assured with a human-ecological understanding of the complexinteractions among environmental,economic and social/cultural factors and with careful planningand management grounded in ecological principles. This paper will probe an integrative methodologyfor achieving environmentally sound, economically productive, and ecologically responsibledevelopment in urban and industrial areas of China through ecological regulation. The central objec-tive is to promote highly efficient resource use rather than high speed development,harmonious sys-tem′s relationship rather than inflexible compartmentalization, and robust and vital self-organizationrather than bureaucrstic control. This ecological order is to be regulated through technological inno-vation,institutional reform, and behavioral incentives that promote positive economic dcvelopmentwhile mitigating negative environmental impacts.

An Investigation Into Career Development Contexts of University Russian Language Teachers in China(1949-2019)From the Perspective of Ecological Theory

Although much research has been conducted on the interactions between the career development of foreign language teachers and their contexts around the world,a literature review reveals that there exists scanty research on the relationship between university Russian language teachers’career development and their contexts in China since 1949.Based on relevant studies on the career development of foreign language teachers and the ecological theory,this paper involves research on the impact that different ecological systems(micro-,meso-,macro-and exo-ones)have played in the career development of Russian language teachers in China.Participants are 10 Chinese Russian teachers of different ages from different universities in different parts of China.Via literature review,narration methods and semi-structured(in-depth)interviews with the help of NVivo,this research finds that Russian language teachers’career development results from multi-faceted interactions of the following contexts:ideology,Russian language educational policies and personal factors as well as college contexts.This paper concludes with some suggestions for improving Russian language teachers’career development in China.

Research on the Regional Ecological Environment Evaluation and Application under the Influence of the Severe Earthquake Disaster

To conduct the ecological restoration and reconstruction of disaster areas after the severe earthquake, such as Wenchuan Earthquake and Lushan Earthquake, this article uses region al ecological environment evaluation and ecological footprint to construct a quantitative analysis model on the basis of ecololgical environment indexes in Mianzhu City. Through this model, resource status of the regional environment in Mianzhu is analyzed, as well as the ecological capacity and the ecological security. Based on the evaluation and analysis, this paper provides multi-path development strategies of ecological restoration and sustainable development of human settlements after the earthquake.

A human－ecology approach to environmental design──An integrative human－ecology design derived from Chinese agricultural cultur eexperiences

Based on fundamental principles of ecology ,the ecological philosophy connotation of Feng-Shui(Wind and Water) concept from experiences of Chinese agricultural culture was first discussed , and then hu-man-ecological implications of Feng-Shui environment architecture is analyzed. As a theoretical integrationbetween human ecology and Feng-Shui theory ,“environment” and “environmental design” concepts were re-examined and given new definitions. With holistic principles of human ecological design in the context ofFeng-Shui , essential technical ways of integrative human ecological design were explored in the presentationof a case study of an urban environmental design in east China.

Two-step calculation method to enable the ecological and human health risk assessment of remediated soil treated through thermal curing

The centralized utilization of heavy-metal-contaminated soil has become the main strategy to remediate brownfield-site pollution.However,few studies have evaluated the ecological and human health risks of reusing these remediated soils.Considering Zn as the target metal,systematic pHdependent leaching and the Community Bureau of Reference(BCR)extraction were conducted at six pH values(pH=2,4,6,8,10,12)for the remediated soil treated through thermal curing.The pHdependent leaching results showed that with the formation of ZnCr2O4 spinel phases,the remediated soil exhibited strong inherent resistance to acidic attack over longer leaching periods.Furthermore,the BCR extraction results showed that the leaching agent pH value mainly affected the acid-soluble fraction content.Moreover,a strong complementary relationship was noted between the leaching and acid-soluble fraction contents,indicating that the sum of these two parameters is representative of the remediated soil risk value.Therefore,we proposed a two-step calculation method to determine the sum of the two heavy metal parameters as the risk value of remediated soil.In contrast to the traditional one-step calculation method,which only uses the leaching content as the risk value,this two-step calculation method can effectively avoid underestimating the risk of remediated soil.
