Problems solved by technology

However, the application of these methods is limited by the cause of soil contamination, and the restoration of contaminated soils on a large scale is very expensive.

Embodiment 1

[0078] Embodiment 1: the collection of lichen

[0079] Three kinds of lichens were collected from an abandoned coal mine located 7km away from the northwest of Taebaek City, Gangwon-do, South Korea. Most of these waste coal mines are not covered by plants, and the waste coal is exposed, and some lichens are scattered in small patches. Moss, Liaodong birch (BetulaSchmidt) and white birch (Betulacostata) grow in some small plots. On the other hand, lichens grow from the outer interface to the inner side where mosses and plants grow (see figure 1 ). Collect the grown lichens, entrust Dr.Harada to classify them, and keep them at the Korea Lichen Research Institute (Shuncheon University, Korea), at the National History Museum and Institute in Chiba Prefecture, Japan; CBM) for replication. The collected lichens were found to be red litmus, dwarf litmus (Cladonia humilisJ.R.Laundon), and Ramulosa litmus (C.ramulosa, J.R.Laundon).

[0080] In addition, lichens growing in this are...

Embodiment 2

[0081] Example 2: Composition analysis of collected lichens

[0082] The 3 kinds of lichens collected from the waste coal mine in Example 1 were washed twice with deionized distilled water, and stored at room temperature for 3 days. In order to analyze the concentration of the components (K, Ca, Mg, Fg, Cu, Mn, Ni, As and Cr) of the lichen body, a modified Tahanen et al. [Tarhanen, S., S. Mets, T. Holopainen and J.Okaanen.1999.Me membrane permeability response of lichen Bryoria fluscescens to wet deposited heavy metal sand acid rain.Environ.Pollut.104:121-129. (Tarhanen, S., S.Mets, T.Holopainen and J. Okaanen, 1999; Membrane permeability responses of B. fluscescens to wet-deposited metals and acid rain. Methods of Environmental Pollution 104:121-129). Specifically, the sub-samples (500 mg) of each clothing species were dried at 90°C for 24 hours, passed through a digestion system at 225°C with HNO 3 and HClO 4高纯（superpur） (10:3ml), perform wet decomposition, and filter to ...

Embodiment 3

[0089] Example 3: Comparison of soil properties in lichen habitats

[0090] The soil characteristic difference between the waste coal mine lichens inhabiting the waste coal mine soil in Example 1 and the waste coal mine soil not inhabited by lichens was analyzed. Specifically, 5 soil samples were randomly taken from the LCC soil and the NBC soil at a depth of 3 cm from the ground. The part below the lichen-like soil (carpet) inhabiting the waste coal mine was collected as the LCC soil sample. After the collected soil was filtered through a 2mm mesh sieve, it was stored at 4°C for the next analysis. These soils were tested by standard laboratory methods [Kim, H.1995. Soil Sampling, Preparation, and Analysis. Marcel Dekker Inc., New York (Kim, H., 1995; Soil Sampling, Preparation and Analysis, Marcel Dekker Inc., Kerr Company, New York)] to measure soil pH. Also, in order to detect heavy metals in the soil, the soil was crushed with a mortar and then filtered through a 100-me...

Abstract

The present invention relates to: a method for restoring the ecology of wastelands such as deserts, abandoned coal mines, oil-polluted areas, volcano-affected areas, areas in which harmful minerals or industrial wastes were discarded, rocky lands, and bare mountains, by using algae with which lichens have a symbiotic relationship, cyanobacteria, lichen-forming fungi, or thalli; and a composition for restoring ecology used for the method. Also, the present invention relates to a method for mass-producing thalli needed in restoring the ecology of the wastelands. The present invention can prevent desertification and yellow dust storms, and reform polluted areas such as abandoned coal mines and oil-polluted areas to be more conducive to the growth of plants, thereby preventing ecological and environmental pollution from deserts, abandoned coal mines, and oil-polluted areas.

Description

technical field [0001] The present invention relates to a method for using lichens to carry out ecological restoration on wastelands such as deserts, waste coal mines, and oil-contaminated lands, a composition for ecological restoration used for the above-mentioned ecological restoration, and lichen-like lichens required by the ecological restoration method and composition methods of mass production. Background technique [0002] Generally, desert areas have little precipitation and fast evaporation of water, which is a wasteland where vegetation can hardly grow. The desert area accounts for more than 1 / 3 of the total land area, and the desert area is still expanding. [0003] This desertification is believed to be the result of a combination of man-made destruction and climatic causes. Man-made damage includes irrigation, logging, environmental pollution, etc. Climate reasons include drought and desiccation. Especially from a climatological point of view, areas with les...
