The Applied Research On Landscape Plants Of Heavy Metal Pollution In Lengshuijiang City

With the rapid development of the global industrial, heavy metal contamination of urban land contradiction has become the most intractable problems. Urban vegetation restoration work is an important part of the mineral ecological environment construction, an important guarantee of the mining area of sustainable development, and gradually by a wide range of national concern. Urban green landscape not only to meet people's visual beauty of the landscape, but also to play the ecological benefits of plant communities.(1) Hunan Lengshuijiang City Landscape Plants Applied study, combined with the theory of plant landscaping and other disciplines to study this particular region, Lengshuijiang City green type of plants used in the investigation, the screening a suitable plant species, and the kind of targeted plant configuration mode of Selected10samples of the study area (including roads green3, green residential area of3units of green3green of the Industrial Zone1), involving the Lengshuijiang Jiangnan, Jiangbei two regional representative plant communities. The composition of the sample plant communities, community types, evergreen and deciduous trees, the green plant community structure, the qualitative comprehensive evaluation.(2) By tracking the growth status of Lengshuijiang City samples experimental species observed and recorded, as well as experimental testing of the heavy metal content in soil, experimental species foundation, soil and plants, screening plants suitable for heavy metal contamination of urban cultivation types.(3) Lengshuijiang City plant applications, and explore the different types of green plant configuration mode, the kind of plant configuration program, the plant configuration mode for the towns of similar heavy metal pollution in China can learn from the experience.
