| 摘要 | Depending on the purpose, Earth & Rock Extraction Projects can be generally classified into the following categories: rock quarry, land aggregates, river sand and gravel, pits for collecting soil rocks for landfill sites, open storage yards and mines. Known as one of the most environmentally sensitive development projects resulting in massive ecosystem and topographical damage, it is fundamentally impossible to be recovered for the earth & rock extraction project from damage due to artificially generated vertical cliffs. In this study, we analyzed the quantitative characteristics of environmental impacts based on the environmental assessment (EA) data of earth & rock extraction projects such as type, size, regional distribution, amount of extraction and period in order to provide a direction for appropriate development. More than 1,800 projects in which EA had been conducted up until 2017 were analyzed. In particular, the current status of earth & rock extraction projects was analyzed in the Capital Area where aggregate demand is the highest and the Chungnam Area where development activity is relatively very high in connection with the adjacent Capital Area. In the case of the Capital Area, a total of 105 EA for earth & rock extraction projects were conducted from 2002 to 2017 including 26 rock quarry development projects. In the case of Chungnam Area, a total of 256 projects were conducted, including 65 rock quarry development projects. For rock quarry development projects, where damages occurred most widely in time and location, the average ratio of the vegetation conservation grade III-IV per project for the Capital Area and Chungnam Area was 56% and 64%, respectively. The ratio of projects where the area of vegetation conservation grade III-IV occupied more than 40% of the total project area was also 72% and 76% in the Capital Area and Chungnam Area, respectively. This indicates that forest damage is very significant in rock quarry development. In addition, as the size of the project increases through the additional EA process, such as partial changes or reprocessing of the EA, species diversity is shown to decrease in all types, indicating that the ecological impact of development continues to get worse. Unlike other development projects, the rock quarry development project is characterized by the fact that the area and amount of rock quarrying approved at the time of initial licensing are constantly expanding over time. Therefore, it may lead to large-scale environmental damage, which requires a careful approach to development. In particular, rock quarry development that causes irreversible damage over a long period should be comprehensively looked at in terms of the necessity and adequacy of the development at metropolitan and provincial levels from the stage of site selection. The necessary minimum capacity should be developed at the supply and demand level. In this respect, the results of this study can be used to establish goals for an aggregate supply and demand plan at a local province level. Based on the overall development status data from local governments on earth & rock extraction projects, it would be possible to conduct an effective EA for the appropriateness of new or expansion projects in relation to supply and demand. |
