Study on System Coupling Interaction of Large-Scale Construction Companies Programme Contracting and

Feng Guo,Tian Huang

Frontiers of Engineering Management 2015, Volume 2, Issue 2,   Pages 137-140 doi: 10.15302/J-FEM-2015022

Abstract: Constant changes in the construction market have resulted in individual projects being challenged to meet the long-term growth needs of large construction companies. Change should be based on the construction of this new model project group, to achieve better interaction, and to allow for a more rapid enterprise development. This paper is based on the system coupling analysis of large-scale construction enterprises and construction projects. A clear system presents itself and forms the basis of the system construction, institutional change and mechanism of the path between base construction projects and business growth.

INTERCROPPING: FEED MORE PEOPLE AND BUILD MORE SUSTAINABLE AGROECOSYSTEMS

Frontiers of Agricultural Science and Engineering 2021, Volume 8, Issue 3,   Pages 373-386 doi: 10.15302/J-FASE -2021398

Abstract:

Intercropping is a traditional farming system that increases crop diversity to strengthen agroecosystem functions while decreasing chemical inputs and minimizing negative environmental effects of crop production. Intercropping is currently considerable interest because of its importance in sustainable agriculture. Here, we synthesize the factors that make intercropping a sustainable means of food production by integrating biodiversity of natural ecosystems and crop diversity. In addition to well-known yield increases, intercropping can also increase yield stability over the long term and increase systemic resistance to plant diseases, pests and other unfavorable factors (e.g. nutrient deficiencies). The efficient use of resources can save mineral fertilizer inputs, reduce environmental pollution risks and greenhouse gas emissions caused by agriculture, thus mitigating global climate change. Intercropping potentially increases above- and below-ground biodiversity of various taxa at field scale, consequently it enhances ecosystem services. Complementarity and selection effects allow a better understanding the mechanisms behind enhanced ecosystem functioning. The development of mechanization is essential for large-scale application of intercropping. Agroecosystem multifunctionality and soil health should be priority topics in future research on intercropping.
