Reasearch On The Mountain Brook Plant Landscape Of Hangzhou

Mountain brook is most illustrative of rustic charm of forests. Plant is important for mountain brook landscape. Based on researching on plant pandscape of natural mountain brook, it can provide technical support for constructing mountain brook landscape featured indigenous plants, rich species, graceful scenery. This paper analysised and summaried the characteristics of plant community and plant landscape, environmental quality of Nine Creeks and Eighteen Gullies.(1) Characteristics of plant species diversity in Nine Creeks and Eighteen Gullies as follows: the first 5 important value of arbors layer were: Metasequoia glyptostroboides> Pterocarya stenoptera> Liquidambar formosana> Elaeocarpus glabripetalus> Phoebe sheareri; the first 5 important value of shrubs layer were: Osmanthus fragrans> Camellia sinensis> Acer palmatum> Jasminum mesnyi> Phoebe sheareri; the first 5 important value of herb layer were:Reineckia carnea>Fagopyrum dibotrys>Polygonum thunbergii>Reynoutria japonica>Polygonum hydropiper.The species diversity index of vertical structure presented a rule: herb layer > shrub layer>arbors layer. Species amount and species diversity index of middle reaches were higher.(2) This paper analysised and summed up the characteristics of plant landscape of Nine Creeks and Eighteen Gullies from plant component, ornamental, landscape composition. Analysised plant landscape in different locations and scales to selecte mainly three points,two lines,one surface. It showed that the landscape of Nine Creeks and Eighteen Gullies had rich species,clear layer,obvious seasonal aspect.(3) Study on the aero-anion concentration showed that: the aero-anion concentration in Nine Creeks and Eighteen Gullies was 711.75per·cm-3 annual average.The value of CI was 0.78 annual average.The result showed that the plant landscape with good air quality. The summer of aero-anion concentration with the highest was 1039.00per·cm-3 averagely.(4) Based on numerous studies of plant landscape, several conclusions were summarized as follows: utilized the resources of wild local plants, enriched plant species; dealed with the ecological characteristics, layed stress on scientific planting arrangement; constructecd steady plant community; created the featured landscape. Based on the existing problems,This paper pointed out some optimization measures for plant landscape of Nine Creeks and Eighteen Gullies: appropriately increased local aquatic plants; energized the maintenance of local plant; limited to the farmhouse, protected the special plant habitat.
