On the account of the requirements on energy and material flows connection, the construction and development of EIPs are contingent for effective environmental plannings.
During the same period the rapid development of ecology, especially bionics, inspired people to apply the natural ecosystem material cycling principle into industry system to build a circular system.

A mutual benefiting network can be built through the physical materials and energy exchange, so that EIP can ultimately achieve zero waste discharged, and coordination among economic, social and environmental sectors [11].
Additionally, measures and programs of construction in the planning should take into account the major industrial chains design, the spatial industry distribution, the selection of the leading industries and key supporting projects, the relevant industrial policies, and the investment and benefit analysis.

The steel plate works as a mechanical shear key (rib-band).
The rib-bands are expected to be the mechanical shear keys between the steel tubes and infill concrete.
Also, the steel materials in this research are provided by the Okabe Corporation and Asahi Kasei Construction Materials Corporation.

Controllable luminescent properties of phosphors Sr2.97-xCaxMgSi2O8: Eu0.012+, Dy0.023+ by adjusting Sr/Ca ratio Chu Jun Fu, Yi Hua Huaa, Yin Hai Wang and Hao Yi Wu School of Physics and Optoelectronic Engineering, Guangdong University of Technology, Guangzhou 510006, China ahuyh@gdut.edu.cn Key words: phosphor; X-ray diffraction; emission spectra; afterglow duration; Abstract.
In further investigations, they examined luminescence of a series of host materials Viz.
Analytical purity of SrCO3, CaCO3, SiO2, MgO, Eu2O3, Dy2O3 were acted as raw materials. 10M% H3BO3 was added as flux.
Hitachi F-7000 fluorescence spectrophotometer was used to reveal the emission spectra of the materials.
Thus, we can make the conclusion that adjusting the value of x of the phosphors Sr2.97-xCaxMgSi2O8: Eu0.012+, Dy0.023+ (x=0, 0.5, 1, 1.5, 2, 2.5, 2.97）can affect the luminescence properties of the materials.

Introduction to Landslides Landslide disasters occur when a mixture of geological materials (e.g., mud, sand, gravel, and rock) and water generate a flow movement as a result of gravitational force.
When rainwater flows into the ground, it scours and erodes geological materials on the land surface downward to a low-lying position.
In addition, rainwater not only saturates and accumulates geological materials and debris in valleys, but also causes an excessive amount of underground water to surface from the discontinuous side of the valley floor.
However, only using the size of slope angle θ to determine the occurrence of landslides is insufficient, because the material composition and vegetation condition of the accumulation layer are also key factors influencing such landslide occurrences.
