Geological Environment Quality Evaluation with Fuzzy Mathematics

Based on features of the geological environment in Tangshan, this paper selects 14 evaluation factors like earthquake and fissure to conduct comprehensive regionalism and analysis. The result shows that the research area can be divided into four parts, Level-I (excellent) area accounting for 0.74% , Level-II (good) area accounting for 37.5%, Level-III (acceptable) area accounting for 52.26%, Level-IV(poor) area accounting for 9.5%.on one hand, the northern mountain area is characterized by collapse, landslide and debris flow. On the other hand, the southern mountain area is characterized by subsidence and seawater encroachment. On the whole, the overall geological environment is poor. Therefore, reasonable land planning and unban construction is of great importance to a coordinated and stable economy in Tangshan.
