Landscape Flower Sea's Spatial Elements Analysis And Its Saving Construction

The paper investigate the main landscape flowers sea in Jiangxi province,during analysis single pattern of Astragalus sinicus flowers sea's spatial pattern and the diversity commercial flowers sea's spatial pattern,the paper choose plaque as a unique to analysis the Astragalus sinicus flowers' individual number,branch,spatial distribution characteristics and spatial orientation to calculate the Astragalus sinicus flowers evenness index and fragmentation index,and then discuss the landscape flowers sea's saving construction.From the result of Astragalus sinicus flowers sea's research found that,in the 40 analysis datas of landscape flowers sea's space in the edge and the middle of the area,the paper used the northern part of the middle data 1.68194 as the parameter of Pmax,which is stand for the maximum evenness index in ideal condition.In the middle and in the edge of the area,the value of Pk(the plants' vertical projection area account for the test plant's sample area ratio)has a prominent difference(Pk<0.01),while in normal conditions,the distribution of landscape pattern which is defined as the value P.In different areas,the P(Pk>0.05)has significantly discrepancy except the northern part(Pk<0.05).The average evenness index of Astragalus sinicus flowers value is beyond 0.84,which has a fairly high evenness index level.While the value of fragmentation index is between 0.09 to 0.37,after the contrast between mean value and standard deviation,the fragmentation index was affected by the orientation of landscape flowers sea.Different orientation of the fragmentation index also influenced by the branch of the flowers,terrains and some other elements,it has even influence the flowers sea's space spatial pattern.The paper used the flowers sea like Helianthus annuus to analysis its CA(area /density),SHDI,geography fluctuation rate)and spatial pattern,finding that the diversity of the landscape flowers sea has a high evenness level,the Pmax are 1.0792,1.5563,1.6021,2.5932 respectively.The diversity of the landscape flowers sea has a significantly difference(Pk<0.05).The flowers' patterns were influenced by the flowers species,terrains and the planting methods.In addition,the paper used the happy sunflower garden in Nan Chang province in the year 2016 as an example to analysis the flowers sea's construction and operation,during discuss the minimun scale of ornament,the choice of landscape flowers species,the design of the terrains,the paper put forward some tips of the landscape flowers space's saving construction.
