This paper selected 6 typical cape-bay sandy beaches in Wenzhou area to sort out the natural environment. The parabolic plane morphology model (MEPBAY) was used to compare the relative positions of the static simulated shoreline with the recent actual shoreline. The advancing and retreating trend of the coastline of the shaped sandy coast was analyzed. The current stability of the coastal beaches of Cape Bay in Wenzhou area was discussed. The results show that the coastline is in a stable state as a whole, and the profile of sandy beaches is mainly divided into four types: concave downward, upward convex, slope, and slope + upward convex combination. The characteristics of the interannual erosion and deposition changes of the profile are mainly divided into three modes: the upward erosion and the downward siltation, the overall erosion type and the basic stable type.

通过选取温州地区6个典型岬湾型沙质海滩,对温州地区自然环境概况进行梳理,运用抛物线平面形态模型(MEPBAY),通过比较静态模拟岸线与近期实际岸线相对位置,研究了岬湾弧形砂质海岸的岸线进退趋势,探讨了目前温州地区岬湾海岸海滩的稳定性。结果表明,海岸线整体处于稳定状态,沙质海滩剖面形态主要分为下凹型、上凸型、斜坡型、斜坡+上凸组合型四大类;剖面年际冲淤变化特征主要分为上冲下淤型、全面冲刷型、基本稳定型三种模式。

通过选取温州地区6个典型岬湾型沙质海滩,对温州地区自然环境概况进行梳理,运用抛物线平面形态模型(MEPBAY),通过比较静态模拟岸线与近期实际岸线相对位置,研究了岬湾弧形砂质海岸的岸线进退趋势,探讨了目前温州地区岬湾海岸海滩的稳定性。结果表明,海岸线整体处于稳定状态,沙质海滩剖面形态主要分为下凹型、上凸型、斜坡型、斜坡+上凸组合型四大类;剖面年际冲淤变化特征主要分为上冲下淤型、全面冲刷型、基本稳定型三种模式。

This paper selected 6 typical cape-bay sandy beaches in Wenzhou area to sort out the natural environment. The parabolic plane morphology model (MEPBAY) was used to compare the relative positions of the static simulated shoreline with the recent actual shoreline. The advancing and retreating trend of the coastline of the shaped sandy coast was analyzed. The current stability of the coastal beaches of Cape Bay in Wenzhou area was discussed. The results show that the coastline is in a stable state as a whole, and the profile of sandy beaches is mainly divided into four types: concave downward, upward convex, slope, and slope + upward convex combination. The characteristics of the interannual erosion and deposition changes of the profile are mainly divided into three modes: the upward erosion and the downward siltation, the overall erosion type and the basic stable type.
