Embodiment 1

[0067] This test was carried out in the Tongguanshan Copper Mine Area of ​​Tongling City, which is located in the central part of Anhui Province, on the south bank of the middle and lower reaches of the Yangtze River. The area is rich in mineral resources, with many mines, complete types of minerals and large reserves. It is one of the famous non-ferrous metal bases and one of the six major copper smelting bases in China. The coordinates are located at 30°46"-31°08" north latitude, 117°44"-118°09" east longitude, bordering Fanchang and Nanling counties in the east, adjacent to Qingyang and Guichi counties in the south, and adjacent to the Yangtze River in the northwest , facing Zongyang and Wuwei counties across the river. Tongling City currently governs three districts (Tongguanshan District, Shizishan District, Suburbs) and one county (Tongling County). The region covers an area of ​​1,113 square kilometers, with a total population of 654,000, including 315,000 non-agricult...

Abstract

The invention provides a method for vegetation restoration in copper mine abandoned land, and belongs to the technical field of ecological restoration and ecological engineering of degraded land. Themethod comprises the steps of S1, land consolidation and soil improvement, wherein the land is leveled, and soil improvement is conducted by means of soil fertilizer and chemical treatment; S2, plantconfiguration, wherein plant materials suitable for local growth are selected, and evergreen tree species and deciduous tree species are reasonably matched according to seasonal variation characteristics; S3, vegetation construction, wherein high-quality nursery stocks growing robustly are selected for planting; S4, cultivating management. Through the steps, a complete vegetation restoration and self-sustaining system is formed for the copper mine abandoned land from improvement to vegetation construction, and the ecological environment of the metal mine abandoned land is effectively improved.According to the method, based on the concept of natural restoration, the vegetation coverage is high, the energy is saved, the environment is protected, the operation method is simple, the construction is convenient, and the method has high application and popularization value.

Description

technical field [0001] The invention belongs to the technical field of ecological restoration of degraded land and ecological engineering, and in particular relates to a method for vegetation restoration of abandoned copper mine land. Background technique [0002] The statements in this section merely provide background information related to the present disclosure and do not necessarily constitute prior art. [0003] Mining has been one of the important activities of social and economic development since ancient times. It not only provides a variety of valuable raw materials for economic construction, such as non-ferrous metals, minerals, etc., but the mining process inevitably destroys the original land. There are topography and landforms, which destroy the original vegetation, cause the degradation of the ecological environment, and at the same time intensify the erosion of water and soil, but also bring a huge amount of solid and liquid waste, and finally form mine waste...
