Coupling and evolution mechanism of infrastructure mega-projects complex ecosystem: Case study on Hong

Zebin ZHAO, Xiaolong XUE, Xinglin GAO, Gang LIU, Hengqin WU

Frontiers of Engineering Management 2018, Volume 5, Issue 1,   Pages 17-29 doi: 10.15302/J-FEM-2018080

Abstract: This paper proposes a concept—the IMP complex ecosystem—to analyze IMP from a broad perspective of organicbased on complex ecosystem theory.First, the coupling process between IMP complex ecosystem subsystems is analyzed through material flowsSecond, a logistic model of the IMP complex ecosystem is proposed by analyzing the evolution conditionsThird, the evolution pattern of the IMP complex ecosystem is determined.

PLANTS AND ENTOMOPHAGOUS ARTHROPODS IN THE AGRICULTURAL LANDSCAPE: A PRACTISE-ORIENTED SUMMARY OF A COMPLEX

Frontiers of Agricultural Science and Engineering 2022, Volume 9, Issue 1,   Pages 63-74 doi: 10.15302/J-FASE-2021427

Abstract:

There is a growing demand for high-quality agricultural products and more countries have adopted landscape management by sowing flowering plants in agricultural fields as an important branch of conservation biological control. However, there has been less concern over the interactions and trade-offs between floral plants and entomophagous arthropods. This paper review progress in pollen/nectar feeding habits of entomophagous insects including parasitoids and predators which are important natural enemies of crop pests in agricultural fields. Factors that influence the preference of different guilds of natural enemies are reviewed to guide the selection of flowering plants in conservation biological control practices. Most studies find that floral resources have positive effects on both biological traits of natural enemies and their abundance and diversity, and this is believed to contribute greatly to pest control. Furthermore, the potential impacts of floral resources on crop yields are also discussed with an emphasis on a guild of entomophagous insects that provides both pest control and pollination services.

Thinking About Establishing New Medicine

Ma Ainai,Zhao Shaoqui

Strategic Study of CAE 2007, Volume 9, Issue 10,   Pages 19-23

Abstract:

Western medicine is based on demonstration science,  and features returning to the original condition.  The division of work is becoming increasingly fine.  There are many achievements in the medicine and cure of illness.  But it always cures illness by dissevering human body. It emphasizes cure while ignoring hominine.  So Western medicine has puzzled itself about how to stick up for whole human body.  Intraditional Chinese medicine,  diagnosis and treatment is based on an overall analysis of the illness and the patient's condition,  which is dialectical and reasonable. It takes heaven, earth and man as an integral whole. There are also and many achievements in the medicine and cure.  Traditional Chinese medicine relies on numeral,  imaging and feeling,  and lacks scientific logos and demonstration science. Combination of the Western and Chinese medicines has been advocated for more than half century, but determinate effects are limited.  The authors, guided by Dr.  Qian Xuesen's idea on systemic science and in accordance to the concept of "break through reduction theory,  develope integer theory,  and achieve both of them with a uniform to systemic theory" ,  advance to establish a new medicine,  that is "Human Body Ecological Medicine" .

Nitrogen pollution and source identification of urban ecosystem surface water in Beijing

Frontiers of Environmental Science & Engineering 2014, Volume 8, Issue 1,   Pages 106-116 doi: 10.1007/s11783-012-0474-z

Abstract: Nitrogen contamination of surface water is a worldwide environmental problem with intensive agriculture and high population densities. We assessed the spatial and seasonal variation in concentrations of total nitrogen and different nitrogen species present in surface-water in Beijing, China. Also, chemical ( ) and isotopic ( ) indicators were used to identify nitrate sources. The results showed that, during 2009 and 2010, nitrate nitrogen concentrations ranged from 0.7 to 7.6 mg·L , ammonium nitrogen from 0.1 to 3.4 mg·L , and total nitrogen from 2.4 to 17.0 mg·L . Inorganic nitrogen accounted for between 60 and 100% of total nitrogen at the ten monitoring sites. Nitrate nitrogen, ammonium nitrogen, and total nitrogen concentrations at the 2 downstream monitoring sites in south-eastern Beijing were significantly higher than those at the other eight upstream monitoring sites ( <0.01). Examination of seasonal variation showed that there was a significant inverse relationship between nitrate nitrogen concentrations and precipitation, and that nitrate nitrogen concentrations peaked in the dry seasons. The information given by the values and nitrate nitrogen concentrations, combined with the ratio distribution, showed that domestic sewage was the major source of nitrate in Beijing. Methods to control and reduce sewage pollution are urgently needed to help manage surface water quality in Beijing.
