Effects of Pigment Indicators on the Color Expression of Leaves of the Colored-leaf Garden Plants

[Objective] In this study, the relationship between the pigments and the color expression of leaves of colored-leaf plants was discussed. [Method] The colors of leaf blades of 6 kinds of plants were analyzed with the Royal Horticultural Soci-ety Colour Chart. The chlorophyl content, carotenoids content and anthocyanin con-tent in leaf blades were determined. In addition, the color types of leaf blades, kinds of pigments, pigment contents and pigment distributions of 6 kinds of plants were compared. [Result] The chlorophyl contents ranked as Populus canadensis Moench （green leaves） 〉 Populus deltoids cv. Zhonghuahongye （purple green leaves） 〉 Populus euramericana cv. Quanhong （red leaves）; Acer palmatum Thunb. （green leaves） 〉 Acer palmatum cv. Atropurpureum （purple red leaves） 〉 Acer pal-matum Thunb. cv. Atropurpureum （red leaves）. The ranking of anthocyanin contents was just opposite. The chlorophyl content was negatively related to the anthocyanin content. The leaf color of plants is determined by various pigments. The more the chlorophyl is, the greener the leaf is. The more the anthocyanin is, the redder the leaf is. In the colored-leaf plants, the chlorophyl content represents about 80% of the content of pigments, the carotenoids content represents about 17%, and the an-thocyanin represents about 3%. There is a difference in the chlorophyl content be-tween colored-leaf plants and green plants. However, the relatively low chlorophyl content wil not hamper the normal life activities of colored-leaf plants. [Conclusion] We hoped to provide reference and basis for the production and landscaping of col-ored-leaf plants.

Three-Dimensional Green Biomass and Environmental and Ecological Benefits of Plants in Yu Yam Ancestral Garden

Yu Yam Ancestral Garden is one of the four famous gardens in Lingnan,China.This study was carried out with the methods of survey and analysis,field measurement and selecting spatial samples methods,dividing Yu Yam Ancestral Garden into 11 plots,for undertaking initial quantitative research on the three-dimensional green biomass(TGB)and environmental ecological benefits(EEB)of the plants.The results showed thatthe arbor played a decisive role in TGB of the Yu Yam Ancestral Garden sample plot,in which the maximum contribution value was evergreen trees.And the Pearson correlation significance analysis was carried out on 11 indicators of the plant morphology and the TGB of the trees-shrubs,drawing a conclusion that the main influencing factor for TGB was the ratio of trees-shrubs,and the simulation equation was Y=2,357.67X3+176.707.EEB of the plants was positively correlated with TGB.A very good way of understanding of the correlation between the TGB of plants and their EEB was proposed,which could provide objective and quantitative theoretical reference data for the plant arrangement of arbor,shrubs and grasses in artificial garden green spaces.It is helpful to understand the importance of artificial garden green spaces ecological value.

Evaluation Indicator System of Low-carbon Landscape in Residential Areas: A Case Study of Garden Plant Landscape

Garden plant landscape is one of the main contents of low-carbon landscape design in residential areas. From the basic theory of garden plant landscaping, we put forth five principles and ideas concerning the building of evaluation indicator system of garden plant landscape, to establish the indicator system with ecological quality, recreational function and aesthetic effect as three layers. According to the characteristics of evaluation system, we use qualitative and quantitative integration method, coupled with analytic hierarchy process (AHP) and expert consulting method, to determine the weight of various factors. And we use fuzzy comprehensive evaluation method to test this indicator system, so as to provide a theoretical basis for the research on evaluation indicator system of low-carbon landscape.

ALPHA SPACE-WHERE PLANTS FLY BEYOND THE VERTICAL GARDEN

In 1996,my interests as a passionate gardener and photo-based artist,that both dated from the 1970s,collided when I made the connection that plants are actually a form of photography;(photography from the Greek-meaning light drawing).Both photography and plants use the magical,mysterious ingredient that is LIGHT and the essential force that drives life on the planet.In fact,the largest photosensitive emulsion we know of is the planet earth.I draw inspiration and endless fascination from the awareness that the earth rotates in space and orbits the sun at a precise distance for the sun’s radiation to affect the elegant process of photosynthesis through the myriad of plants that have evolved and grow on the planet.The earth is a three dimensional living photograph.The atmosphere and biosphere are also key factors that mediate the harshness of radiation bombarding the earth and nurture life on the planet that we know and depend upon.The process is an amazing thing and something we should revere and protect.Imagine the earth as a basket ball,wrapped in the thinnest paper you could find.The thickness of this delicate paper is equivalent to the atmosphere,and the depth of the paper’s texture is thicker than the tallest trees,even thicker than the tallest high rise buildings!Image sequences from NASSA shows how vegetation grows,dies back,changes colour with the seasons,how the“photographic image”that is our planet alters.Increasingly human intervention plays a larger role in transforming the image of the globe we inhabit.Imagine foliated land as a photo-sensor(like in a digital camera).

Research on Arrangement of Urban Garden Plants in the Perspective of Ecological Adaptability

With the increasing deterioration of urban environment, strengthening construction of garden green land was one of the effective ways to ameliorate urban environment. However, as designers only focused on the landscape effect of garden plant arrangement and neglected the relationship between plants and natural environment, it resulted in poor growth of some plant community even the disappearance of some communities. Therefore, good landscaping effect could be achieved only when garden layout requirement was considered and suitable cultivation environment was selected based on plants ecological feature, giving full play to its landscaping and ecological function. The study discussed the arrangement of garden plants mainly in the perspective of temperature, light, water, atmosphere and soil environmental factors which were suitable for garden plants, so as to realize the high unity of scientificity and artistry garden plants arrangement, provide a save, comfortable and healthy living and working environment for residents, achieve virtuous cycling development of urban ecological system and promote sustainable development of the city.
