Coastal and offshore regions are regarded as the key zones exposed to marine disasters. Zhejiang province, located on the verge of the East China Sea, is one of the provinces mostly affected by marine disasters that have brought serious economic losses and casualties. The data of marine disasters in Zhejiang province, which occurred during the period from 2000 to 2016, were selected and analyzed. The results indicate that (1) storm surge, wave, and red tide are the main kinds of marine hazards in the coastal region of Zhejiang province. (2) a total of 1,099 marine disasters occurred in the coastal region of Zhejiang province during 2000—2016, and resulted in about 275 deaths or missing with 18.544 billion yuan of direct economic losses. In addition, marine disasters are mainly distributed in Zhoushan City, Ningbo City, Taizhou City, and Wenzhou City of Zhejiang province.

With the rapid development of urbanization, land use change has occurred in most karst mountain regions of North China over the last decade, so studying landscape pattern changes induced by urbanization would have implicational significance to regional planning and sustainability. Based on RS, GIS, and field investigation, land use change induced by urbanization in Jinan city belonging to the karst mountainous area of North China was analyzed over 30 years from 1987 to 2018, and further the landscape response of these changes was explored. The results indicate that (1) the most obvious changes have occurred in both urban/built-up land area and cropland area with rapid urbanization development in Jinan’s karst area, and the former increased by 246.4 km2 but the latter decreased by 343.3 km2 from 1987 to 2018; (2) landscape pattern of land use is profoundly changed by quick urbanization in the period from 2000 to 2018, but does not siginificently from 1987 to 2000; and (3) in the monitoring period, the cropland’s shape inclines to fragmentation and regularization, and the shapes of urban/built-up land and barren land have become increasingly distinct from the patch class level; from patch landscape level, the artificial landscape type (urban/built-up land) is increasingly dominant but the natural landscape type (grassland) is decreasingly dominant, thereby resulting in the disturbance of urban karst environment of Jinan city. Therefore, a protection policy should be taken to achieve strong urban karst sustainable development of North China.
