Planting understory groundcover plants has apparent ecological and agroforestrial benefits since it can greatly improve the ecological environment. However, this requires that the groundcover plants should have a certain shade tolerance. This study examined the shade tolerance of Glechoma heder acea by examining the light-utilization characteristics of it including the rate and state of its growth under different light conditions. The results showed that, G. hederac ea has the lower light compensation point, the higher light saturation point, the maximum apparent quantum efficiency, and the maximum net photosynthetic rate, which reflected that G. hederacea had a wider use range of effective light radiation and a stronger shade-tolerance ability. In stronger light conditions, G. hederacea grew faster and had longer stems, shorter internodes, also the rooting and branching situations were better compared with that in weaker light. However, this plant grew normally in weaker light, and invasion of weeds was less prominent with well-growth. Thus, G. hederac ea, as a kind of shadeendurance groundcover plant, was also adaptable to the full-light environment and could be used in the plant practice of forest interplanting, playing an important role in ecological diversity and environment protection.

Store buildings usually have distinct characteristics of significant depth, high human density and heat-emitting sources, a high simultaneity usage coefficient for the air conditioning system, etc. The aim of this paper is to develop a rational rating method for green stores. By comparing the commonly used evaluation methods of green buildings, an assessment method for green store buildings in China has been developed. This method references the rating requirements set by the "China Green Building Evaluation Standard" and weighted credits for each category. This method attempts to avoid the effect of "imbalanced performance" when labeling green buildings. The Expert Group Decision AHP method has been used to develop the weighting system for green store buildings. The weight distributions highlight the importance of indoor environmental quality, energy efficiency and operation management within store buildings. © 2014 Elsevier Ltd. Source
