When major problems caused by the coal industry are explored, such as heavy metal contamination in the soil, suspended matter in the water, and flooding that may affect nearby residents, a more ecological solution is often desired. Therefore, in this design, a landscape focused approach, using phytoremediation, water purification, etc. is proposed.

Based on the analysis of the topography and slope, the sites are divided into three categories. After initial treatment of the site by physical consolidation methods, such as land preparation, slope cutting, and soil restoration, physical consolidation methods are used for initial treatment.

Design should be attempted as a positive solution to environmental problems. At the same time, new future development plans for the site should also be proposed. For example, the development of terraced agriculture based on high technology, or the development of wetland tourism in order to protect the environment. In addition, the design is also expected to achieve the objective of optimising the site's environment and the living conditions of local residents, and to give the site a new lease of life.
