Technical Field

The invention relates to the field of landscaping, in particular to a vegetation planting structure of a regeneration land.

Background

Brown land refers to land left over by industrial economic activities. During the latter half of the 20 th century, developed countries and regions left a large number of early factory sites in urban centers with the upgrading of industrial structures and the suburbization of the center of gravity of the industry, and many of these sites had varying degrees of pollution.

Brown land refers to waste, unused or underutilized industrial or commercial land and facilities, and is often more complicated than other development processes due to objective or unexpected environmental pollution during the re-development and utilization of such land. According to legal regulations, the development of such land is restricted by environmental protection departments, and development activities must be carried out according to procedures permitted by the environmental protection departments, including necessary remediation of pollution and reaching the specified standards.

Therefore, for the special land, how to utilize a new vegetation planting structure to achieve the purpose of treatment is particularly important, and the prior art is applied to planting structures such as districts, river banks and parks, and cannot be directly applied to the special environment.
