Abstract:

The eco-geological environment quality shows the overall situation of regional geological action and ecological spatial distribution. In order to provide the basis for the ecological protection and restoration of the southwest coastal areas of Malaysia of the north coast   of Malacca Strait and the investment and construction of “One Belt and One Road”, GIS technology and hierarchical analysis method are combined. Based on the data set of Malaysia basic geology and geological disaster remote sensing geological application and mapping project results, the eco-geological environment quality evaluation index system of the southwest coastal area of Malaysia along the north coast of  Malacca Strait was constructed and comprehensively evaluated. Through the analysis of the results, the eco-geological environment quality of the study area was divided into four grades: excellent, good, medium and poor. The area of excellent and good area was larger, which was 2 753.31 km2 and 2 960.33 km2, respectively, accounting for 34.19% and 36.76% of the total area of the study area, and mainly distributed in the hilly areas of the northern coastal plain. The medium and poor districts are 1 702.72 km2 and 618.57 km2, accounting for 21.37% and 7.68% of the total area of the research area, respectively, and are mainly distributed in southern Sembilan central , Selangor and northern Malacca. According to the evaluation results, the eco-geological environment quality of this area is good on the whole. The  excellent area and good area account for 70.00% of the total area of the study area. The medium  area and poor area are mainly restricted by the stratigraphic structure and ecological conditions, so it is necessary to carry out environmental protection and ecological restoration according to specific problems.
