Huzhou Municipal Party Committee and Municipal Government attach great importance to ecological environment management. As early as 1995, the Municipal Bureau of Land and Resources ordered the closure of all quarries in Ren Huang Mountain, which protected the natural ecological environment destroyed by human beings to some extent. With the development of economy and the acceleration of urban construction, the urban area of Huzhou City has now expanded to the vicinity of Ren Huang Mountain. It is urgent for Huzhou City to completely eradicate Ren Huang Mountain and create a good living environment for people. After entering the new century, Huzhou took Ren Huang Mountain as the first batch of pilot projects to implement comprehensive improvement of mine ecological environment.
The ecological control project of Ren Huang Mountain consists of two parts: geological disaster control and vegetation restoration. Generally speaking, Huzhou Municipal Government entrusts the Ninth Geological Brigade of Zhejiang Province and the North Zhejiang Geological and Mineral Investigation and Research Institute to be responsible for the design and construction. The prophase geological disaster control was designed and constructed by Zhejiang North Institute of Geology and Mineral Resources, and its main task was to eliminate geological disasters such as collapse, landslide and debris flow induced by human mining activities. Later vegetation restoration is to restore the original ecological features, improve the living environment of the surrounding residents, and provide places for local residents to climb mountains and exercise. After extensive investigation and selection of various enterprises engaged in mine environmental management in China, the Ninth Geological Brigade of Zhejiang Province decided that Zhejiang Fu Huan Ecological Technology Co., Ltd. would undertake the mountain slope protection and vegetation restoration and greening project in Ren Huang. According to the plan, the project will be completed by the end of 65438+February this year. After implementation, more than 200 mu of land resources can be added. After the project is completed, Ren Huang Mountain will be integrated with the surrounding natural landscape after treatment, so as to achieve the purpose of natural harmony and restore the original appearance of Ren Huang Mountain.
Specifically, the ecological control scheme of Ren Huang Mountain is mainly based on ecological greening, blasting slope cutting and unloading, supplemented by supporting retaining wall and drainage ditch. Considering that Ren Huang Mountain is a high and steep rocky slope with poor site conditions and sunny slope, in order to achieve the effect of ecological greening, Zhejiang Fu Huan Ecological Technology Co., Ltd. adopts the second-generation foreign soil blowing and attaching technology independently developed and updated, which can not only ensure the ecological greening effect of greening, but also ensure the combination of evergreen seasons and grass irrigation.
For the vegetation restoration area covered with soil, the vegetation restoration is carried out by using rich stones in the mining area, and the coverage thickness is greater than1m. The coverage area is dominated by drought-tolerant and barren evergreen trees such as Phyllostachys pubescens, Ligustrum lucidum, Mamou, Populus davidiana and Pinus massoniana. In order to maintain soil erosion and achieve greening effect, the inner surface of the area is sprayed with water. For the vegetation restoration area outside the retaining wall, because the stone berm is high, it is a soft and hard landscape, which makes the whole treatment area more harmonious with the surrounding area. Trees and shrubs are planted on the outer side of the berm by "digging a big pit to return the soil". Plant species include Ligustrum lucidum, coral, oleander and other trees and shrubs.
