Resources Survey And Landscape Application Of Wild Perennial Plants In Wenzhou

Perennial plants refer to plants that underground part can be wintering and can continue to grow in next year. Perennial plants are rich in natural resources, a wide range of extensive management and propagation techniques of cultivation.With the people’s living standard has been improving and the environmental pollution is becoming increasingly serious, the landscapes of nature has been destroyed in city greening. So, the urban garden greening has been developing towards the direction of plant landscaping and calculating ecology. With the rapid development of urbanization in Wenzhou, the habitats of biology in city disappear gradually, and urban ecological environment has been further destructed by habitat fragmentation. In recent years, the urban garden afforestation has been getting rapid development, but several issues have been exposed. Firstly, greening has been thought better than beautify. The evergreen plants, most in the urban greening, have more embodiment of green effect instead of beauty of color and flavor. Secondly, the green plant species have not inadequate diversity, the local characteristics aren’t reflected. Thirdly, the green plant species are most introduced form other places, instead of native species, so There are some security and applicability problems.Based on the above issues, combining the rich resources of wild perennial plants in Wenzhou, based on several field investigation, the wild perennial plants of applied prospect were screened, and analysis and application of these plants were made. The main results are following:1、 The edge of mountain path, forest margins and under-forest were investigated in emphasis in several representative areas, such as HongShuang forestry centre of RuiAn, BaiZhangJi of WenCheng, TongLingShan of WenCheng, XianJuQiao of TaiShun, SiHaiShan of YongJia, NanJi islands of Ping Yang.293species of wild perennial plants were total investigated, belonging to68families and203genus. The list and picture information of wild perennial plants of ornamental and utilization prospect were compiled. 2.From three of the appreciation, adaptability, and potential applications, a comprehensive evaluation index system of wild perennial plants was established used by24evaluation parameters and analytic hierarchy process (AHP), combined the characteristics of the perennial root plants. Nineteen kinds of wild perennial plants, belonging to19genera and14families, with ornamental value suitable for garden application were filtered out from150wild perennial plants used this evaluation index system.3.Configuration rules in the garden application were provided according to the perennial plant ecological nature, landscape function, and the characteristics of the surrounding environments. Four configurations were summarized in garden application here, such as, configuration of special perennial plants, hybrid configuration of the perennial plants, configuration perennial plants combined to annual, and biennial flowers, and the configuration between perennial plants and the bush. At last, part of the designs was implemented in Yangfushan Park, and achieved some good results.
