Survey On The Application Of Ground Covers And Evaluation Of Indigenous Resources For Ground Covers In JiAn, Jiangxi

Indigenous groundcover plants have abundant species,good plant resistance and compatibility.And they also have the high ornamental value, the local characteristics and the rich level changes.After planting,they does not need to be replaced frequently,the management to be extensive. Along with the people esthetic idea's changing,the application of indigenous groundcover plants in landscape architecture receive the workers' and researchers' attention day by day.This research has carried on the diagnosis to the present situation of Jian groundcover plants application in landscape architecture.And to investicate the JiAn indigenous groundcover plant resources including their shape characteristics,the habitat characteristics and and the main ornamental characteristics.Integrated assessment to indigenous groundcover plant resources in jiAn was developed by the linearity weighted integrative method of mathematical model.Utilization and conservation items of indigenous groundcover plants resources in JiAn have also been discussed based on the results of the basic characteristics analysis and integrated assessment.The findings analysis indicated:1st,the Jian town center city green space lawn area which were built accounts for the sown area 41.5%,the flowering plant area accounts for the sown area 0.5%,other groundcover plant area accounts for the sown area 8%,in the city green space the application groundcover plant type total 15 kinds,subordinate in 10 branches,the perennial herb class nine kinds,fill a kind of three kind lowly,vine class three kinds,and mainly by formosa grass(Zoysiatenuifolia),bermuda grass(Cynodon dactylon),onion blue(Zephyranthes candida),fragrant-flowered garlic blue(Zephyranthes grandiflora Lindl),dwarf lilyturf(Ophiopogon japonicus),Yunnan Huang Xin (Jasminum mesnyi) primarily.The applications of groundcover plants in the Jian green space which are building show that plant species monotone, ornamental bad,the coverage fraction low,disposes improper.As circumstances permitted,the reasonable development and utilization of indigenous groundcover plant resources would be one way to solve this present situation efficiently.2nd,the basic characteristics of indigenous groundcover plant resources in JiAn were including the aspects as follows:(1) Now in the five sits,there are totally 87 species of indigenous groundcover plants that can be identified,they belong to 8l genera of 54 families.Among them,the dominant families are Composites and Rosales.(2) According to the results of integrated assessment to the 87 species of indigenous groundcover plants in JiAn,there are 12 species have highest integrated value,48 species have higher integrated value,24 species have general integrated value,and 3 species have lower integrated value.The result shows that indigenous groundcover plants in JiAn possessed higher exploitation.(3)On the base of the integrated assessment results,19 species of indigenous groundcover plants which showed outstanding value for landscape application in Jian are especially recommended.3rd,the research on applying and promoting JiAn indigenous groundcover plant resources is at the start stage.Firstly,draws up the vegetative practice and the related laws and regulations to strengthen ecological systems and protecting the ecological environment,at the same time put an end to predatory mining,rural land has been done on the sustainable use of plant resources.Secondly,strengthen the basis of studies on indigenous groundcover plant resources that will build the foundation for development work in the future.Thirdly,ornamental and the high application value spices should be screenedto be domesticated, be propagated and be applied in a plan way step by step.At last, Establishing reproduction bases,constantly summing up experience and promoting good plant varieties have been cultivated management skills and production experience,accelerate the wild plants have been large-scale production.
