Analysis Of Heze City Plant Zhaowang River Park Landscape Construction And Ecological Benefits

This article investigate the Heze city Zhaowang River Park species of landscape plantsand community. Analysis the aero-anion concentration and plant antibacterial function inecological park, the results are as follows:1. The Zhaowang River park has a variety of tree community structure.The seasonalaspect structure is rich and colorful.The landscape effect is good and has great ornamentalvalue. There are un-reasonable aspect in plant disposition and community collocation as also.In the growth stage for most trees, the growth potential has a large space, the state of trees isgood.2. The diurnal and annual variation of air-anion concentration have obviousregularity.The double-peak curve can be clearly seen during the diurnal variation rule.In theday, the maximum appeared at10a.m. and2:00p.m., and the minimum appeared in themorning.There were obvious regularity between annual variation and seasonal variation inair-anion concentration. In august, air-anion concentration is so highest that air quality isbest,winter is opposite.The air-anion concentration and air quality are highest in summer,lowest in winter, Spring and autumn are between them.Woodland air-anion concentration issignificantly negative correlated to the temperature and has significant positive correlationwith air relative humidity. The air-anion concentration and air quality of sunny conditionswere greater than that of cloudy conditions. There are significant differences betweendifferent types of green space.Waterfront green space has the highest air-anion concentrationand air quality.Whereas air-anion concentration and air quality of green space which aremixed with arbor, shrub and grass were greater than that of other simple forest types.3. Take a leaf extract from Southern magnolia, Camphor, Peachblossom, Weeping willow,Purple-leaf plum,Cedar, and Ligustrum lucidum ait. Do bacteriostatic experiment with Coli, Fecal enterobacteriaceae, Staphylococcus aureus, Shigella and Salmonella. Cedar and Ligustrum lucidum ait have an obvious inhibitory effect on Fecal enterobacteriaceae, Staphylococcus aureus,Shigella and Salmonella,but have no obvious effect on coli.Peachblossom,weepingwillow and purple-leaf plum have a slight effect on test bacteria. Southern magnolia and camphor have no obvious effect on test bacteria.
