【摘要】：利用2007-2014年辐射沙洲的遥感影像获取陆岸岸段的围填海用海面积信息,结合淤泥质潮滩围填海强度与潜力定量评价模型,对辐射沙洲陆岸及其各分岸段进行了围填海开发状况评价及开发潜力预测。结果表明:在5级为上限的强度评价体系下,在2007—2014年间辐射沙洲陆岸岸段总体,围填海开发强度等级由1级进入3级,开发强度由32.8hm~2/km上升至147.87hm~2/km,围填海压力中等,对岸段的后续开发有一定影响。其各分岸段开发强度差异较大,2014年各分岸段:射阳河口至梁垛河闸岸段开发强度为2级,处于可持续发展状态;梁垛河闸至新北凌口岸段及东灶港至蒿枝港岸段开发强度为4级,开发压力较大,预测可供开发年限仅为12a;新北凌口至东灶港岸段开发强度为3级,预测可供开发年限为8a。该结论可为合理规划淤泥质海岸围填海工程进度与规模,维护海岸带资源环境可持续利用提供参考。
[Abstract]:Using the remote sensing images of radiative sandbanks from 2007 to 2014, the information of reclaimed sea area was obtained, and the quantitative evaluation model of reclamation intensity and potential of muddy tidal flat was combined. The evaluation of reclamation development status and the prediction of development potential are carried out on the land banks of radiative sandbanks and their sub-seacoasts. The results show that under the intensity evaluation system with upper limit of grade 5. From 2007 to 2014, the level of reclamation development intensity increased from level 1 to level 3. The development intensity has increased from 32.8hmmmmmm2km to 147.87hmmnm-2 / km. the reclaimed pressure is moderate, which has a certain influence on the subsequent development of the coastal section, and there is a great difference in the development intensity of each seashore segment. In 2014, the development intensity of each bank segment from Sheyang Estuary to Liangduanghe sluice is 2 grade, which is in the state of sustainable development. The development intensity of the section from Liangduhe Gate to Xinbei Ling Port and the section from Dongzhao Port to Artemisia Port is 4 grade, and the development pressure is high, and the predicted development period is only 12 years. The development intensity of the section from Xinbei Lingkou to Dongzhao Port is grade 3, and the predicted development life is 8 years. This conclusion can be used to reasonably plan the progress and scale of the silty coastal reclamation project. To maintain the sustainable utilization of coastal resources and environment.
