Sustainable development potential evaluation
Ecological flood detention pond
The slopeland rural community environment has been deteriorated for human activities and natural hazard area overlapping. The most notorious debris-induced hazards are located at the landslide, channel bed, and torrent areas. The related authorities have devoted themselves to the hazard prevention works by huge expenses. However, the slopeland hazards can not be solved and rural village economics can not be increased efficiently. For the above reasons, some public opinions propose that human have to retreat from slopeland. Recently, the concepts of bio-engineering methods are introduced and used on engineering designs. The disharmony structures are gradually replaced by natural materials. The rural village shows the splendor landscape different with before. Therefore, the rural village evaluation processes need be revised to follow up the new situations. In this study, the upstream rural village at the Da-An River upstream was used to be the study area. Using GIS overlapping analysis and SWOT method, current advantages and disadvantages can be simulated the different strategies by external opportunities and threats. By the quantify evaluation, the potential evaluation model can be established to provide decision-makers. From the results, there are very few differences between traditional hazard prevention measures and zero action. However, combining the ecological concerns and spatial correlations, the evaluation results from the restricted development policies under bearable environmental impacts are easy to identify from derived social, economic, landscape, and safety scores. In the meantime, the riparian and estuary areas may become the hot spots by the human intrusion during the SWOT evaluation processes. From the results, using the ecoturism planning, ecological detention pond placement, and recreational channel bed improvement works to increase developing opportunities will be the rural village development focus.
