It is very important to develop and utilize land resources in complex terrains such as slopes and valleys. When leveling and developing slopes and valleys, it is necessary to cut high and fill low because of the large terrain fluctuations. Setting up vertical retaining structures at the land red line and then backfilling and leveling the site can effectively improve land utilization.
